[HOWTO] - Access CP/M Floppy's created with Teledisk using libdsk & cpmtools

This HOWTO: will explain how to Install libdsk Version 1.3.5 & cpmtools Version 2.18, along with the dependencies, that allow READ ONLY
access to Teledisk (*.TD0) files with your Debian 7.x install.

BEFORE YOU TRY A COMPILE YOU MUST INSTALL SOME REQUIRED SOFTWARE:
Typically you need to install build-essential, and the headers for the kernel you are running.

Debian Wheezy (Ver 7.x) Packages needed for Software Compile:
1. Build-Essential
2. Linux debian 3.2.0-4-amd64 Headers (or the Headers for your Version)

Code: Select all: uname -r

will tell you the kernel you are currently running.

Code: Select all: sudo apt-get install build-essential linux-headers-$(uname -r)

will install the software needed to successfully compile your source code.

Install Additional Required Software to Compile libdsk and cpmtools:
Install libncurses5-dev:

Code: Select all: sudo apt-get install libncurses5-dev

At this point you may have had several directory changes or updates, and your system likely needs updated with:

Code: Select all: sudo updatedb

It's a good idea to execute this command at a regular interval, to keep the database updated for the locate command.

DOWNLOAD THE SOURCE:
Create a new subdirectory of your choice to contain the downloaded source code.
Download both source packages from:

http://www.seasip.info/Unix/LibDsk/libdsk-1.3.5.tar.gz
http://www.moria.de/~michael/cpmtools/c ... .18.tar.gz

Create a subdirectory to contain the source. I used /home/larry/Downloads/cpmtools
Copy both source files to /home/larry/Downloads/cpmtools, then extract the source folders

Code: Select all: tar -zxvf libdsk-1.3.5.tar.gz tar -zxvf cpmtools-2.18.tar.gz

The next step you need to do is to find the "SHELL" and "env" you are using, and how many shells are installed and available.

1. env -- Display the current environment, find what Shell is being used with the following command.....

Code: Select all: env | grep SHELL=

To get a list of available shells on your system, look in the /etc/shells file. This will list the available shells with their complete
path names. You can see the list of available shells by running:

Code: Select all: cat /etc/shells

Additional shells may be available in your distribution's software repositories. Performing a search for the term "shell" in your
package manager should provide you with a list of alternative command line shells.

If you want to experiment with a shell, just for now, you can launch a shell from within the existing shell. For example, if you
ant to run the tcsh shell, you can run:

Code: Select all: tcsh

When you are finished exploring tcsh you can type exit to return to the default shell. Once you have found a shell you want to continue using
you can switch to the default shell by running the chsh command. For example, if you want to switch to using the tcsh shell, you can run

Code: Select all: chsh -s /usr/bin/tcsh

Please note that you must provided the full directory path to the new shell.

2. locate .*rc -- Find the current logged in user's home shell Configuration file (*rc)... use:

Code: Select all: locate .*rc

REF:
http://en.wikipedia.org/wiki/Unix_shell
Bourne shell (sh)
Almquist shell (ash)
Bourne-Again shell (bash)
Debian Almquist shell (dash)
Korn shell (ksh)
Z shell (zsh)
C shell (csh)
TENEX C shell (tcsh)
other shells..............

There may be a .bash_profile file in /home/loginuser along with .bashrc file. You can put configurations in either file,
and you can create either if it doesn’t exist. But, why two different files? What is the difference?

According to the bash man page, .bash_profile is executed for login shells, while .bashrc is executed for interactive non-login shells.

If .bash_profile exists in /home/user with the following information already inserted:

Code: Select all: PATH=$PATH:$HOME/bin export PATH

just append your path modifications here instead of the .bashrc file. (ie. CentOS 6)

You need to list the *rc file to verify the contents and set the PATHS. I'm ASSUMING a Bash shell......Your may be different!

3. cat .bashrc -- List the configuration file, then append the proper search paths for the users shell with edit.

Code: Select all: export LD_LIBRARY_PATH=???????????????????????????????? export LIBRARY_PATH=??????????????????????????????????? export C_INCLUDE_PATH=????????????????????????????????? export CPATH=??????????????????????????????????????????

Mine happens to now be:

Code: Select all: export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib export LIBRARY_PATH=/usr/lib:/usr/local/lib export C_INCLUDE_PATH=.:/usr/include:/usr/local/include export CPATH=.:/usr/include:/usr/local/include

But, your's may vary accordingly. You won't be able to cut & paste mine, unless your system is built exactly like mine. It's up to you to locate
exactly where all the libs and includes are located. That is what all the previous commands should have helped you do. Just because you have
/usr/lib & /usr/local/lib included....doesn't mean your needed lib is in that path.

That is where your detective work comes to play. SEARCH and use grep to locate the libs.

Once you have the env set either reboot or reset the env. Once again, your system command for this can/may be different.

4. source .bashrc -- Reset the environment to what we need for Compiles, assuming the SHELL is bash. This may not be available on your system.....

REF:
http://linux.about.com/library/cmd/blcmdl1_ulimit.htm

source filename [arguments]
Read and execute commands from filename in the current shell environment and return the exit status of the last command executed from filename.v If filename does not contain a slash, file names in PATH are used to find the directory containing filename. vThe file searched for in PATH need not be executable. vWhen bash is not in posix mode, the current directory is searched if no file is found in PATH. vIf the sourcepath option to the shopt builtin command is turned off, the PATH is not searched. vIf any arguments are supplied, they become the positional parameters when filename is executed. vOtherwise the positional parameters are unchanged. vThe return status is the status of the last command exited within the script (0 if no commands are executed), and false if filename is not found or cannot be read.

VERIFY the env is correct:

5. env -- Display the new environment to verify the paths.............PARTIAL DISPLAY of SPECIFIC's I NEEDED...

Code: Select all: LIBRARY_PATH=/usr/lib:/usr/local/lib LD_LIBRARY_PATH=/usr/lib:/usr/local/lib CPATH=.:/usr/include:/usr/local/include C_INCLUDE_PATH=.:/usr/include:/usr/local/include

Append the new CP/M Floppy Disk Definitions for cpmtools to the /usr/local/share/diskdefs file.
Append these sample diskdefs to /usr/local/share/diskdefs & /etc/cpmtools/diskdefs

Additional Definitions for diskdefs:

Code: Select all: diskdef amp1 seclen 512 #= Sectors xx,512 tracks 40 #= (Cylinders * Sides) = 40*1 = 40 sectrk 10 #= Sectors 10,xxx blocksize 2048 #= (128*(BLM+1)) = 2048 maxdir 64 #= (DRM+1) = 64 skew 0 #= SKEW 0 boottrk 2 #= OFS = 2 os 2.2 end # setfdprm /dev/fd0 DS DD ssize=512 cyl=40 sect=10 head=2 diskdef amp2 seclen 512 tracks 80 sectrk 10 blocksize 2048 maxdir 128 skew 0 boottrk 2 os 2.2 end # setfdprm /dev/fd0 zerobased SS DD ssize=512 cyl=40 sect=10 head=1 # Kaypro II diskdef kpii seclen 512 tracks 40 sectrk 10 blocksize 1024 maxdir 64 skew 0 boottrk 1 os 2.2 end # setfdprm /dev/fd0 zerobased DS DD ssize=512 cyl=40 sect=10 head=2 # Kayro IV diskdef kpiv seclen 512 tracks 80 sectrk 10 blocksize 2048 maxdir 64 skew 0 boottrk 1 os 2.2 end diskdef zor1 seclen 512 tracks 80 sectrk 10 blocksize 2048 maxdir 64 skew 0 boottrk 2 os 2.2 end diskdef zor2 seclen 512 tracks 160 sectrk 10 blocksize 4096 maxdir 128 skew 0 boottrk 2 os 2.2 end

UPDATE: 08/13/2014 cpmtools Version 2.19 has been released with additional disk definitions
I've attached my definition file because I've added (and tested) several additional definitions.
CORRECTED SKEW=2 in Radio Shack Model 4 CP/M Definitions.

Copy these sample libdskrc definitions to an External file at /home/user/.libdskrc
.libdskrc contains:

Code: Select all: sudo cp diskdefs /usr/local/share/diskdefs sudo cp diskdefs /etc/cpmtools/diskdefs cp .libdskrc /home/user/.libdskrc

TYPICAL COMPILE STEPS: (from within your source directory)

Code: Select all: ./configure make clean make sudo make install

"make clean" won't remove anything on the first compile, but will clean up on a successive compile.

Build libdsk:

Code: Select all: cd ~/Downloads/cpmtools cd libdsk-1.3.5 ./configure make sudo make install sudo make install-man

Build cpmtools:

Code: Select all: cd .. cd cpmtools-2.18 ./configure --with-libdsk=/usr/local make sudo make install

VERIFY cpmls executes properly:

Code: Select all: cd .. cpmls

If you don't get the following cli usage message:

Usage: cpmls [-f format] [-T libdsk-type] [-d|-D|-F|-A|[-l][-c][-i]] image [file ...]

try this command:

Code: Select all: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/usr/local/lib"

Then do:

Code: Select all: cpmls

Open a Teledisk *.TD0 file containing compressed CP/M Files, and view the CP/M Directory with the following commands:

Code: Select all: man cpmls cpmls -f kpii -T tele,kpii -d kii-b282.td0 cpmls -f kpiv -T tele,kpiv -l KAY2SYS.td0 cpmls -f amp1 -T tele,amp1 -i ampro.td0 cpmls -f zor1 -T tele,zor1 -l compat32.td0 cpmls -f zor1 -T tele,zor1 -d compat32.td0 man cpmcp cpmcp -f a1 bb2mon.img 0:*.mac /home/larry/Downloads/cpmtools/xfer1

Now that you need to modify or add CP/M definitions to 22DISK, LIBDSK, and/or CPMTOOLS, this document will assist you
with locating the proper parameters for the three definition files for:

22DISK - CPMDISKS.DEF
LIBDSK - .libdskrc
CPMTOOLS - diskdefs

Code: Select all: ~/path/to/your/22Disk/CPMDISKS.DEF /home/user/.libdskrc /usr/local/share/diskdefs (also located at /etc/cpmtools/diskdefs)

Some Helpful Hints on Developing a Disk Definition from Scratch

If possible, run programs on the CP/M system to help get the necessary information for building a
new definition. The following files may be transferred by RS-232C if a Terminal Program is available,
or by PIPMODEM.COM (PIPMODEM.DOC & PIPMODEM.ASM)

1. CPMADR.COM - Finds addresses used by the CP/M system.

2. DPB.COM - Finds Disk Parameter Block information.
DPB.BAS - Same, but runs under MBASIC. (Located in 22DISK.TXT)

3. PROBE.COM - Probes CP/M System and Drive for information.
Note: The previous four programs may not locate and
display accurate information for some CP/M systems.

4. SKEW.COM - Finds disk SKEW information.

5. Execute the following "STAT" commands on system in question.
Note: "Control P" will allow a hardcopy of the information.

STAT DEV: - Displays current DEVICE information.
STAT VAL: - Displays current STATUS information.
STAT USR: - Displays current USR information.
STAT A*.* $S - Displays detailed file information.
STAT DSK: - Gives some detailed disk information for logged drive.
STAT A: DSK: - Gives some detailed disk information for A:.
STAT B: DSK: - Gives some detailed disk information for B:.

If you have a functional CP/M system, you can use DDT to find the Disk Parameter Block and the
information is stored there for each drive.

1. Log the drive you wish to locate the DPB data for. I will use A; for this example
2. Run DDT and enter the code below:
DDT
-f0100,0200,00
-A0100
0100 mvi c,1f
0102 call 5
0105 rst 7
0106 . #period to exit assembler
-d0100
0100 0e1fcd0500FF
-g0100
*105
-x #display register HL
The contents of register HL is the address of Drive A: DPB. If you display that address
(mine was F5E3) you will see F5E3: 2400040F0154007F00C00020000200.

RPT = 0024 = The number of 128 byte records per track.
BSH = 04 = The block shift count.
BLM = 0F = The block mask.
EXM = 01 = The extent mask.
DSM = 0054 = Disk storage maximum (the largest block number).
DRM = 007F = Directory maximum (the largest directory entry).
DAB = 00C0= Directory Allocation Block AL0: = 00 & AL1: = C0
CKS = 00020 = Directory check size.
OFF = 0002 = Track offset (number of reserved tracks).

SPT: Number of sectors per track. May differ from RPT if physical sectors
are other than 128 bytes in size.

SSZ: Sector size code:
0 = 128 bytes per sector
1 = 256 bytes per sector
2 = 512 bytes per sector
3 = 1024 bytes per sector

NTK: Number of tracks (35, 40, 77, or 80). The number of tracks can be determined by formatting
a Floppy, or with Anadisk. Anadisk will also tell you the sector size and SKEW.

Quite frequently, the only information available when developing a definition for 22DISK is a
diskette with a few files and nothing more.

Here's a guide on what to do if you'd like to try working up a definition yourself:

1. Get a copy of Sydex's ANADISK. This utility will furnish far more information than will any
other program. A typical disk definition follows:

Ampro Little Board Z80 running CP/M 2.21
BEGIN AMP1 Ampro - SSDD 48 tpi 5.25"
DENSITY MFM, LOW
CYLINDERS 40 SIDES 1 SECTORS 10,512 SKEW 2
SIDE1 0 1,2,3,4,5,6,7,8,9,10
BSH 4 BLM 15 EXM 1 DSM 94 DRM 63 AL0 080H AL1 0 OFS 2
END

New 22DISK definitions require the following information:

DENSITY xx,xx
CYLINDERS xx
SIDES xx
SECTORS x,xxxx
SKEW x
SIDE1 0 x,x1,x2,x3, , ,xn
SIDE2 x x,x1,x2,x3, , ,xn
ORDER x
BSH x
BLM x
EXM x
DSM x
DRM x
AL0 x
AL1 x
OFS x (or SOFS x)
COMPLEMENT (unlikely)

New LIBDSK definitions require the following information:

[title]
description = DESC The description of the format as shown by (for example) dskform–help.
sidedness =TREATMENT How a double-sided disk is handled. This can either be alt
(sides alternate – used by most PC-hosted operating systems),
outback (use side 0 tracks 0-79, then side 1 tracks 79-0 – used
by 144FEAT CP/M disks), or outout (use side 0 tracks 0-79, then
side 1 tracks 0-79 – used by some Acorn formats). If the disk is
single-sided, this parameter can be omitted.
cylinders = COUNT Sets the number of cylinders (usually 40 or 80).
heads = COUNT Sets the number of heads (usually 1 or 2 for single- or double- sided).
sectors = COUNT Sets the number of sectors per track.
secbase = NUMBER Sets the first sector number on a track. Usually 1; some Acorn formats use 0.
secsize = COUNT Sets the size of a sector in bytes. This should be a power of 2.
datarate = VALUE Sets the rate at which the disk should be accessed. This is one of: HD, DD, SD or ED.
rwgap = VALUE Sets the read/write gap.
fmtgap = VALUE Sets the format gap.
fm = Y or N Sets the recording mode - Y for FM, N for MFM.
multitrack = Y or N Sets multitrack mode.
skipdeleted = Y or N Sets whether to skip deleted data.

The LIBDSK Data rate will be one of:
RATE_HD, /* Rate for High-density disc - 1.2Mb in 5.25" 96 tpi drive, or 1.44Mb in 3.5" 96 tpi drive */
RATE_DD, /* Rate for Double-density disc - 360k in 5.25" 48 tpi drive, or 720K in 3.5" 48 tpi drive */
RATE_SD, /* Rate for Double-density disc - 180k in 5.25" 48 tpi drive, or 360k in 3.5" 48 tpi drive */
RATE_ED /* Data rate for 2.8Mb 3.5" in 3.5" 96 tpi drive */

New CPMTOOLS definitions require the following information:

diskdef title
seclen xxx #= Sectors xx,1024
tracks xx #= (Cylinders * Sides) = 80*2 = 160
sectrk xx #= Sectors 5,xxx
blocksize xxxx #= (128*(BLM+1)) = 2048
maxdir xxx #= (DRM+1) = 256
skew x #= may be 1 thru 6, or so
boottrk x #= OFS = 2
os x.x #= 2.2, or 2, or 3
end

So, if you know the 22DISK parameters, you can easily fill in the details for LIBDSK & CPMTOOLS. As an
example, here is an AMPRO LITTLE BOARD DSDD 96 tpi 5.25" Definition for all three software packages.

BEGIN AMP4 Ampro - DSDD 96 tpi 5.25"
DENSITY MFM,LOW
CYLINDERS 80 SIDES 2 SECTORS 5,1024 SKEW 2
SIDE1 0 17,18,19,20,21
SIDE2 1 17,18,19,20,21
ORDER SIDES
BSH 4 BLM 15 EXM 0 DSM 394 DRM 255 AL0 0F0H AL1 0 OFS 2
END

[amp4]
description = Ampro - DSDD 96 tpi 5.25"
sides=alt #=/* XXX Provisional depending on 22DISK Definition */
cylinders = 80 #= Cylinders = 80
heads = 2 #= Sides = 2
sectors = 5 #= Sectors 5,xxx
secbase = 17 #= First Sectors from (SIDE1 0 17)
secsize = 1024 #= Sectors xx,1024
datarate = DD #= Data Rate = SD, DD, HD, ED
rwgap = 12 #=/* XXX Provisional */
fmtgap = 23 #=/* XXX Provisional */
fm = N #= FM or MFM (Likely MFM)
multitrack = N #= Most likely N
skipdeleted = Y #= Most likely Y

diskdef AMP4
seclen 1024 #= Sectors xx,1024
tracks 160 #= (Cylinders * Sides) = 80*2 = 160
sectrk 5 #= Sectors 5,xxx
blocksize 2048 #= (128*(BLM+1)) = 2048
maxdir 256 #= (DRM+1) = 256
skew 0 #= may be 1 thru 6, or so
boottrk 2 #= OFS = 2
os 2.2 #= 2.2, or 2, or 3
end

2. Run ANADISK on the diskette in SECTOR EDIT mode with the display set for "HEX".
Note that the interleave (or SKEW) is given, as well as the number, size and addresses of
sectors. You now have data for: DENSITY, CYLINDERS, SIDES, SKEW SIDE1 and SIDE2.

3. Locate the directory on the diskette. Almost invariably, it starts on the first sector of a track.
If for some reason it can't be found on the first sector of a track, try using the SEARCH feature
to find a "FILE" name that exists on the disk. The number of tracks or sectors up the point
where the directory begins will give the figure for OFS or SOFS. The directory stands out
because it shows file names every 32 bytes, or every other line on the ANADISK display.

Directory was located at Cylinder 0, Side 0, Sector 2:

4. Examine the first directory entry. The second 16 bytes (the second line of the entry) gives a list
of allocation unit numbers (AUN) belonging to the file. The first one of these will tell how many
allocation units have been reserved to hold the directory. Thus, if the first allocation byte is 02,
two allocation units have been allocated to the directory. Another thing to note is whether the
allocation unit number appears to be an 8 bit or 16 bit quantity. For example, if an entry has the
following form:

00 50 49 50 20 20 20 20 20 43 4F 4D 00 00 00 10 .PIP COM....
04 00 05 00 06 00 00 00 00 00 00 00 00 00 00 00 ................

the allocation unit designators are 4, 5 and 6 and are 16 bit quantities. On the other hand, the
following item:

00 50 49 50 20 20 20 20 20 43 4F 4D 00 00 00 10 .PIP COM....
04 05 06 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

shows the same allocation units, but as 8 bit quantities. If 16 bit quantities are involved, more
than 255 allocation nits are defined for the diskette, if an 8 bit quantity, less than 256 units.
This serves as a check for later computations. In any case, the first allocation number of the
first directory entry gives the number of bits to be set in AL0 and AL1.

Allocation Unit Number (AUN)
02 AL0 11000000B Al1 0
04 AL0 11110000B Al1 0

The following information shows a detailed breakdown of all the information in the the first and
second directory entries.

00 - Valid file (E5 for Erased File)
32 32 44 49 53 4b 20 20 44 4f 43 - File name 22DISK DOC (11 bytes)
00 - Extent (used for large files)
00 - S1 (Digital Research Reserved)
00 - S2 (Digital Research Reserved)
80 - Number of records in this extent
02 00 03 00 04 00 05 00 06 00 07 00 08 00 09 00 - allocation units

Note: 02 is the first AUN.

00 - (Continuation of above file)
32 32 44 49 53 4b 20 20 44 4f 43 - File name 22DISK DOC (11 bytes)
01 - Extent (used for large files)
00 - S1 (Digital Research Reserved)
00 - S2 (Digital Research Reserved)
80 - Number of records used
0a 00 0b 00 0c 00 0d 00 0e 00 0f 00 10 00 11 00 - allocation units

Note: Unused allocation units will be 00.

5. Starting with the first directory sector, advance the sector (and track, if necessary) until you
find the data belonging to the first file. Unused directory entries are almost always filled out
with a pattern of E5's. The number of sectors dedicated to the directory will give an indication
of both the number of directory entries and the allocation unit size.

Suppose that a our hypothetical diskette shows 8 sectors of 512 bytes allocated to the directory.
Since a directory entry is 32 bytes long, the number of directory entries possible for this format is:

16 entries/sector X 8 sectors = 128 entries total
or
((Sector Size in Bytes/32) X Sectors to DIR) -1 = DRM

Thus, DRM is one less than this or 127. Since we know that these 8 sectors represent 2 allocation
units or 4,096 bytes, the Allocation Unit Size (AUS) is:

4,096 / 2 = 2,048 bytes
or
((Sector Size in Bytes) X Sectors to DIR) / AUN = AUS

Given this, we can use the following table to compute the values for BSH and BLM:

+--------------+-------------+------------+
| Unit Size | BSH | BLM |
+--------------+-------------+------------+
| 1,024 | 3 | 7 | +----------+
| 2,048 | 4 | 15 | ------+ This one |
| 4,096 | 5 | 31 | +----------+
| 8,192 | 6 | 63 |
| 16,384 | 7 | 127 |
+--------------+-------------+------------+

7. We still need a value for EXM and DSM. DSM is simply the total number of allocation units
on the diskette, not counting the system OFS area. Let's assume that our diskette has an offset
of 2 tracks and is single-sided with 40 cylinders with 8 sectors per track. The value of DSM
is then:

((40 cylinders X 1 side) - 2 tracks) X 8 sectors X 512 bytes) =
155,648 bytes / 2,048 = 76 Allocation units, total

To get EXM, we then use the following table:

+--------------+-------------+-------------+
| Unit Size | DSM < 256 | DSM > 255 |
+--------------+-------------+-------------+
| 1,024 | 0 | na |
| 2,048 | 1 | 0 |
| 4,096 | 3 | 1 |
| 8,192 | 7 | 3 |
| 16,384 | 15 | 7 |
+--------------+-------------+-------------+

8. That's almost the complete picture, but for the SIDE1 and SIDE2 sector ordering. This is the
hardest to determine of any of the parameters. Find a readable text file on the diskette and
piece the text back together by observing how words break across sector boundaries. After a
bit, a pattern in the ordering will become apparent, such as:

1, 3, 5, 7, 2, 4, 6, 8

9. The ORDER value can be determined on double-sided diskettes by observing whether file
data appears to move from one track to the next on the same side (CYLINDERS), or appears to
go from one side to the other and then advance to the next cylinder (SIDES). It should be
noted here that there are several different CP/M Format layouts possible. For ORDER, there
are five different options in 22DISK: SIDES, CYLINDERS, EAGLE, COLUMBIA, or EVEN-ODD

Here are the 22DISK choices for those Parameters:

ORDER SIDES specifies that first one side then the other is written/read
before the cylinder number is advanced.

ORDER CYLINDERS specifies that all tracks on the first side are recorded
then all tracks on second side. Tracks on side 0 are written
from 0 up and side 1 down to 0.

ORDER EAGLE same as CYLINDERS except both sides start at zero or outermost
track.

ORDER COLUMBIA same as CYLINDERS except tracks are sequential from side
0 to side 1 ie. 0 - 79 for a 40 track disk.

ORDER EVEN-ODD means side 0 contains even-numbered tracks and side 1
contains odd-numbered tracks.

Here are the LIBDSK choices for those Parameters:

SIDES_ALT, /* Track n is cylinder C C0H0,C0H1,C1H0,C1H1,......*/
SIDES_OUTBACK, /* Tracks go (head 0) 0,1,2,3,...37,38,39, then
(head 1) 39,38,37,...,2,1,0 */
SIDES_OUTOUT, /* Tracks go (head 0) 0,1,2,3,...37,38,39, then
(head 1) 0,1,2,3,...37,38,39 */

10. COMPLEMENT is rare. Generally, if a diskette appears to be formatted with values of 1A
instead of E5, the data on the diskette is complemented.

11. Last resort for information will require a memory dump from F200 hex through FFFF to
provide all the DBP information as hex bytes. It will be necessary to dig through 3584 (E00)
bytes of data to locate the DPB information. Most systems follow the layout shown below.

(Hex values starting in memory at Fxxx)
RPT: (word) total # of logical 128-byte sectors/track
BSH: (byte) data allocation block shift factor,
determined by data block allocation size
1k=3 2k=4 4k=5 8k=6 16k=7
BLM: (byte) data allocation block mask (2**[BSH-1])
1k=7 2k=15 4k=31 8k=63 16k=127
EXM: (byte) extent mask, determined by the data block
allocation size and the number of disk blocks
1k=0 2k=1 4k=3 8k=7 16k=15 if DSM < 256
1k=n 2k=0 4k=1 8k=3 16k=7 if DSM > 256
DSM: (word) disk size in blocks-1; determines the total
storage capacity of the disk size
DRM: (word) directory size-1; determines the total number
directory entries that can be stored on this
drive. DRM: = ((# dir entries) / 4) -1
AL0: (byte) alloc0 (1100 0000) 2 blocks/dir
(1000 0000) 1 block/dir
AL1: (byte) alloc1 (0000 0000)
Note that AL0: and AL1: are taken together
as a single sixteen-bit mask for the number
of blocks of directory allocation.
(1100 0000 0000 0000) 2 blocks/dir
(1000 0000 0000 0000) 1 block/dir
CKS: (word) directory check vector size
fixed media: CKS = 0
removable media: CKS = (DRM + 1)/4
OFF/SOFF: (word) # of reserved system tracks or sectors (offset)
at the beginning of the (logical) disk.
Usually the directory begins at the first
sector of the track defined by this number.

By formatting a disk the number of tracks can be determined, which will give the first byte to
look for. The SPT will be followed by 00 and the value for BSH and BLM will be the third and
fourth bytes.

BSH and BLM will be one of the following Hex values:

BSH 3 or 4 or 5 or 6 or 7
BLM 7 or 0F or 1F or 3F or 7F

The above information should be fairly easily to locate.

LIBDSK - SUPPORTS

Disk image types supported:

remote : Remote LibDsk instance
...........libdsk server at the far end of a serial connection
...........Remote LibDsk server, most likely at the other end of a serial line.
rcpmfs : Reverse CP/MFS driver
...........Host directory presented as a CP/M filesystem
...........Reverse CP/M filesystem. A directory is made to appear as a CP/M disk. This is an experimental
...........system and should be approached with caution.
floppy : Linux floppy driver
...........Host system's floppy drive (under Linux, DOS, or Windows).
dsk : CPCEMU .DSK driver
...........Disc image in the DSK format used by CPCEMU. The format of a .DSK file is described in the CPCEMU documentation.
edsk : Extended .DSK driver
...........Disc image in the extended CPCEMU DSK format.
apridisk : APRIDISK file driver
...........Disc image in the format used by the ApriDisk utility. The format is described in apridisk.html.
qm : CopyQM file driver
...........Disc images created by Sydex's CopyQM. This is a read-only driver.
tele : TeleDisk file driver
...........Disc images created by Sydex's TeleDisk. This is a read-only driver.
ydsk : YAZE YDSK driver
...........Disc image format used by the yaze and yaze-ag CP/M emulators.
raw : Raw file driver
...........Raw disc image - as produced by "dd if=/dev/fd0 of=image"
...........On systems other than Linux, DOS or Windows, this is also used to access the host system's floppy drive.
myz80 : MYZ80 hard drive driver
...........MYZ80 hard drive image, which is nearly the same as "raw" but has a 256 byte header.
simh : SIMH disc image driver
nanowasp : NanoWasp image file driver
...........Disc image in the 400k Microbee format used by the NanoWasp emulator. This is similar to "raw", but the
...........tracks are stored in a different order. LibDsk also applies a sector skew so that the sectors are
...........read/written in the logical order. Strictly speaking, it should not do this (when libdsk is used
...........with cpmtools, cpmtools is the one that does the skewing) but cpmtools cannot handle the skewing
...........scheme used by the Microbee format.
logical : Raw file logical sector order
...........Raw disc image in logical filesystem order. Previous versions of LibDsk could generate such
...........images (for example, by using the now-deprecated-logical option to dsktrans) but couldn't then write
...........them back or use them in emulators.
cfi : CFI file driver
...........Compressed floppy image, as produced by FDCOPY.COM under DOS. Its format is described in cfi.html.

LibDsk is a library that attempts to create uniform functions for accessing:

* Floppy drives, under Linux, Windows and MSDOS;
* Raw "dd" disc images (including floppy drives under other Unixes);
* .DSK files (as used by CPCEMU, JOYCE, XZX, etc.)
* MYZ80 hard drive images (as used by MYZ80 and JOYCE).
* Various other disc image formats which this margin is too small to enumerate.

LIBDSK has drivers for:
Raw files (including /dev/fdn).
Raw files, rearranged into logical filesystem order.
.DSK files, as used in CPCEMU, JOYCE and other Sinclair/Amstrad emulators.
MYZ80 hard drive image files.
NanoWasp floppy image files.
.CFI (Compressed Floppy Image) files, as created by FDCOPY.COM under DOS.
The Linux floppy drive (supports CPC System and Data formats, which the standard "Raw file" driver does not).
The Windows 3.x/95/98/ME/NT/2000 floppy drive.
The DOS floppy drive (via the PC BIOS).
CopyQM files (read-only)
TeleDisk files (read-only)
APRIDISK image files
The experimental LDBS format
rcpmfs - a backend that makes a Unix/Windows directory appear to be a CP/M disc image.
Another instance of LibDsk over a serial line.

LIBDSK also has the following default CP/M Floppy definitions included.

Code: Select all: pcw180 : PCW / IBM 180k cpcsys : CPC System cpcdata : CPC Data pcw720 : PCW / IBM 720k pcw1440 : PcW16 / IBM 1440k ibm160 : IBM 160k (CP/M-86 / DOSPLUS) ibm320 : IBM 320k (CP/M-86 / DOSPLUS) ibm360 : IBM 360k (CP/M-86 / DOSPLUS) ibm720 : IBM 720k (144FEAT) ibm1200 : IBM 1.2M (144FEAT) ibm1440 : IBM 1.4M (144FEAT) acorn160 : Acorn 160k acorn320 : Acorn 320k acorn640 : Acorn 640k acorn800 : Acorn 800k acorn1600 : Acorn 1600k pcw800 : PCW 800k pcw200 : PCW 200k bbc100 : BBC 100k bbc200 : BBC 200k mbee400 : Microbee 400k mgt800 : MGT 800k trdos640 : TR-DOS 640k ampro200 : Ampro 40 track single-sided ampro400d : Ampro 40 track double-sided ampro400s : Ampro 80 track single-sided ampro800 : Ampro 80 track double-sided myz80 : MYZ80 8Mb pcpm320 : IBM 320k (CP/M-86 / DOSPLUS)

Additional CP/M Disk Definitions can be added in /home/user/.libdskrc

DSKTRANS — Copy from one floppy or image file to another

SYNOPSIS:
dsktrans [-itype TYPE] [-otype TYPE] [-iside SIDE] [-oside SIDE] [-icomp COMP] [-ocomp COMP]
[-idstep] [-odstep] [-retry COUNT] [-format FMT] [-first CYLINDER] [-last CYLINDER]
[-comment TEXT] [-comment @FILE] [-md3] [-logical] [-apricot] [-pcdos] [-noformat] INPUT-IMAGE OUTPUT-IMAGE

dsktrans copies floppy discs or images, optionally converting image types. This is a high-level copy which assumes
that the disc has a straightforward geometry; all the tracks are assumed to have the same layout of sectors, and
interleave is not preserved.

To convert the imagedisk .imd images back to .img (raw - you can rename .raw to .img) use:

Code: Select all: dsktrans -otype raw -format sin2 ElwroG1.dsk ElwroG1.raw dsktrans -otype raw -format amp1 AmprOrig.dsk AmprOrig.raw cpmls -d -T raw,elwro -f elwro ElwroG1.img cpmls -d -T raw,pcw720 -f elwro ElwroG1.img cpmls -d -T edsk,elwro -f elwro ElwroG1.dsk

libdsk can also be used standalone to convert from a Cylinder/Head/Sector disk image (as used by, for example, VirtualBox)
to a dump in file system order:

dsktrans -itype raw -otype logical -format ibm1440 infile.vfd outfile.cpmfs
and back:
dsktrans -itype logical -otype raw -format ibm1440 infile.cpmfs outfile.vfd

dsktrans -otype floppy 720CPM86.IMG /dev/fd0

dsktrans /dev/fd0 filename.ufi -otype raw
cpmcp -f amstrad filename.ufi 0:filename .

dsktrans -itype qm -otype raw input output
or even
dsktrans -itype qm -otype floppy input /dev/fd0

http://simonowen.com/samdisk/formats/

Is there a utility to convert the imagedisk .imd images back to .img raw?

Found the solution using simon owen's samdisk

Code: Select all: samdisk test.imd test.raw

rename .raw to .img and it even booted !!!

Another solution is to use ImageDisks IMDU

Code: Select all: IMDU file.img file.raw /E /B

If you want more information about the image use the following command:

Code: Select all: IMDU file.img file.raw /E /B /D > file-log.txt

Then read the file-log.txt document.

UPDATE 01-25-2017

The current version of cpmtools is 2.20 and is located at: http://www.moria.de/~michael/cpmtools/f ... .20.tar.gz
The current version of libdsk is 1.4.2 and is located at: http://www.seasip.info/Unix/LibDsk/libdsk-1.4.2.tar.gz
Note that libdsk now requires lyx and lyx-common to be installed.

You may have built cpmtools (without libdsk) or you may have built cpmtools with libdsk, to allow more disk image access possibilities.

In your searches for CP/M images you've likely stumbled on Dave Dunfield's site with several different System Images in .IMD format at:
http://www.classiccmp.org/dunfield/img54306/system.htm

Let's access a few of these IMD files with cpmtools (with libdsk).

I've selected one of the CP/M files at random, to test cpmtools and libdsk:

http://www.classiccmp.org/dunfield/img54306/d/zorba.zip

The first thing to do is download some .ZIP files, extract their contents in separate subdirectories, and read the included README.TXT

The first Windows command I use in XP is:

Code: Select all: IMDU ZORBA1.IMD > ZORBA1.TXT

which gives me a lot of detail about the .IMD image:

IMageDisk Utility 1.18 / Mar 07 2012
IMD 1.01: 3/08/2005 11:16:41

Zorba Personal Computer

System Disk (BIOS version 1.7)A

CP/M 2.2 CP2-865-04553

CBASIC CBA-865-04553

Copyright 1981 by Digital Research, Inc.

0/0 250 kbps DD 10x512
80 tracks(40/40), 800 sectors (465 Compressed)

This information tells me it's a 40 Track Image with 2 Heads, and with 10 Sectors of 512 Bytes. You will need this
information to select the proper definition for cpmtools and libdsk.

ZORBA.ZIP contains:
ZORBA1.IMD, ZORBA2.IMD, ZORBA3.IMD, ZORBA4.IMD, ZORBA5.IMD & README.TXT

Next, you need to create the .RAW image files of all .IMD files in Windows or in DOSBOX. I use IMDU:

Code: Select all: IMDU ZORBA1.IMD ZORBA1.RAW /E /B IMDU ZORBA2.IMD ZORBA2.RAW /E /B IMDU ZORBA3.IMD ZORBA3.RAW /E /B IMDU ZORBA4.IMD ZORBA4.RAW /E /B IMDU ZORBA5.IMD ZORBA5.RAW /E /B

OR

Code: Select all: IMDU ZORBA1.IMD ZORBA1.RAW /E /B /D > ZORBA1.TXT IMDU ZORBA2.IMD ZORBA2.RAW /E /B /D > ZORBA2.TXT IMDU ZORBA3.IMD ZORBA3.RAW /E /B /D > ZORBA3.TXT IMDU ZORBA4.IMD ZORBA4.RAW /E /B /D > ZORBA4.TXT IMDU ZORBA5.IMD ZORBA5.RAW /E /B /D > ZORBA5.TXT

To create the .RAW images for accessing with cpmtools, or cpmtools with libdsk.

The zorba definitions are:

Code: Select all: # ZOR1 Zorba - DSDD 48 tpi 5.25" - 512 x 10 diskdef zor1 seclen 512 tracks 40 sectrk 20 blocksize 2048 maxdir 64 skew 1 offset 10240 boottrk 0 os 2.2 end # libdsk data below [zor1] description = ZOR1 Zorba - DSDD 48 tpi 5.25" - 512 x 10 #sides = extsurface cylinders = 80 heads = 2 secsize = 512 sectors = 10 secbase = 1 datarate = DD # ZOR2 Zorba - DSDD 96 tpi 5.25" - 512 x 10 diskdef zor2 seclen 512 tracks 80 sectrk 20 blocksize 4096 maxdir 128 skew 1 offset 10240 boottrk 0 os 2.2 end # libdsk data below [zor2] description = ZOR2 Zorba - DSDD 96 tpi 5.25" - 512 x 10 #sides = extsurface cylinders = 160 heads = 2 secsize = 512 sectors = 10 secbase = 1 datarate = DD

The ZOR1 definition is the one that fits the IMDU Imagedisk information.

cpmtools (without libdsk) commands

Code: Select all: man cpmls man cpmcp cpmls -f zor1 -d ZORBA1.RAW

ASM COM : DDT COM : ED COM : LOAD COM
MOVCPM COM : PIP COM : STAT COM : SUBMIT COM
XSUB COM : DUMP COM : M80 COM : L80 COM
CREF80 COM : LIB80 COM : CBAS2 COM : CRUN2 COM
XREF COM : SGEN COM : PATCH COM : SETUP COM
FORMAT COM : TRACKRD COM : RELOAD COM : VT52 KEY
TALK COM

Code: Select all: cpmcp -f zor1 ZORBA1.RAW 0:*.COM /home/larry/IMDs/zorba cpmcp -f zor1 ZORBA1.RAW 0:vt52.key /home/larry/IMDs/zorba more vt52.key

cpmtools with libdsk commands

Code: Select all: cpmls -f zor1 -T raw,zor1 -d ZORBA1.RAW cpmcp -f zor1 -T raw,zor1 ZORBA1.RAW 0:*.COM /home/larry/IMDs/zorba cpmcp -f zor1 -T raw,zor1 ZORBA1.RAW 0:vt52.key /home/larry/IMDs/zorba more vt52.key cpmcp -f zor1 -T raw,zor1 ZORBA1.RAW /home/larry/IMDs/zorba/*.COM 0:

So, now you can easily copy files to and from your .RAW Images using cpmtools (or cpmtools with libdsk).

But, maybe you also need to create a new .IMD from the .RAW image.

From DOSBox, the BIN2IMD utility will create an .IMD of a .RAW Image.

Code: Select all: BIN2IMD input-file output-image [option-file] [options] BIN2IMD X.RAW X.IMD DM=2 N=80 SS=512 SM=1-8 /2

Where the Options are:
opts: /1 - 1-sided output
/2 - 2-sided output
/C - write Compressed sectors
/U - write Uncompressed sectors
/V[0|1] - Verbose output
C=text | @file - image Comment
N=#cylinders - set Number of output cylinders
DM[s]=0-5 - track Data Mode
SS[s]=128-8192 - track Sector Size
SM[s]=n[,n-n][n.#] - track Sector numbering Map
CM[s]=n[,n-n][n.#] - track/sector Cylinder Map
HM[s]=n[,n-n][n.#] - track/sector Head Map

and

DM= sets the Data Mode, which must be one of:
0 = 500 kbps FM \ Note: kbps indicates transfer
1 = 300 kbps FM > rate, not the data rate,
2 = 250 kbps FM / which is 1/2 for FM
3 = 500 kbps MFM encoding.
4 = 300 kbps MFM
5 = 250 kbps MFM

SS= sets the Sector Size, and must be one of:

128, 256, 512, 1024, 2048, 4096 or 8192.

See: Imagedisk's IMD.TXT for more details.

UPDATE 09-19-2017

GETTING GARBAGE DIRECTORY LISTING??

If you have had trouble getting a directory listing, there are a few things that can be tried to get a valid directory listing.

Here is an example directory listing that is corrupt.

Code: Select all: cpmls -D -f als1 61KCPM3B.RAW

larry@debian:~/IMD-118/Alspa$ cpmls -D -f als1 61KCPM3B.RAW

------------ ------ ------ ---- ----------------- -----------------
'W2D!D.4M+ 0K 0 R

4 Files occupying 2K, 594K Free.

Looking at the output of the the imagedisk utilities, I see that the first track is 26 sectors x 128 bytes (3328 bytes), while the remaining
tracks are 8 sectors x 1024 bytes (622592 bytes). I used hexedit in Debian to locate the CP/M Directory listing. It was at 0x2D00
which is at 11520 decimal. With that information I can try two stanzas in my als1 definition to see if that works.

Code: Select all: imdu 61KCPM3B.IMD 61KCPM3B.RAW /B /E /D >> 61KCPM3B.TXT

Original Definition

Code: Select all: # ALS1 Alspa - SSDD 8" - 1024 x 8 diskdef als1 seclen 1024 tracks 77 sectrk 8 blocksize 2048 maxdir 128 skew 1 boottrk 2 os 2.2 end

Modified Definition:

Code: Select all: # ALS1 Alspa - SSDD 8" - 1024 x 8 diskdef als1 seclen 1024 tracks 77 sectrk 8 blocksize 2048 maxdir 128 skew 1 boottrk 0 #0x2D00 = 11520 offset 11520 os 2.2 end

I still get an error when I try to get a directory listing. So, I change back to my Original Definition.

There has to be another way to get the correct Directory listing, and then get the files extracted.
Maybe I can write the first track so that it matches the remaining 76 tracks and try to get a directory listing.
I know I won't be able to boot a floppy created from this file, but I want the files extracted, and don't need
to boot this created image.

So, I use dd to write a track 0 which will contain 8 sectors of 1024 bytes. This will become the
first track of the output file. The Linux command to do this is:

Code: Select all: dd if=/dev/zero of=test.raw count=8192 bs=1

That creates Track 0 which is now also 8192 bytes long. Then, I simply add the remainder of the data to
the "test.raw" file. That Linux command is:

Code: Select all: dd if=61KCPM3B.RAW skip=3328 count=622592 bs=1 seek=8192 of=test.raw conv=notrunc

I skip the first 3328 bytes of the input file (Track 0), then copy the remaining bytes ((1024 * 8)*76) OR 76 Tracks.
The Directory listing is now sane, and I can copy the files to a folder.

Code: Select all: cpmls -D -f als1 test.raw

OR

Code: Select all: cpmls -f als1 -T raw,als1 test.raw

OR

Code: Select all: cpmls -f als1 -T raw,als1 -D test.raw

UPDATE 05-16-2018

I've just downloaded a *.TD0 or *.IMD file and created a *.RAW file but cpmtool is having problems with the first two tracks
being a mixed variety of single & double density. How I proceed? How do I get a good Directory Listing, and extract good files?

This [HOWTO] assumes you know how to use BOSBox. If you don't know how to use DOSBox, here is a good Tutorial:

http://forums.debian.net/viewtopic.php?f=16&t=61888&p=359786&hilit=HOWTO#p359786

If the Saved file is a .TD0 (TELEDISK) file, run the TD02IMD utility in DOSBox from a Linux Terminal (Command Window).

Code: Select all: C:>td02imd JADEDD.TD0 > JADEDD.TXT

If the Saved file is a .IMD (IMAGEDISK) file, run the IMDA utility in DOSBox from a Linux Terminal.

Code: Select all: C:>imda JADEDD.IMD >> JADEDD.TXT C:>imdu JADEDD.IMD JADEDD.RAW /B /E /D >> JADEDD.TXT

Exit DOSBox.

The TD02IMD utility gave results similar to these:

Which gives you a bit of information on the version of TELEDISK and Image information
such as DS/DD 80 Tracks, Sector Size, and total sectors converted.

The imda and imdu also add information to the log file (JADEDD.TXT)

77 tracks(77/0), 2026 sectors (117 Compressed)

So, now you know the first two tracks are different size, and the remainder of the Image is written at
500 kbps, is SD, and Number of sectors is 26 and they are 128 bytes, with 77 Tracks on side 0.

No information is given for the Floppy definition to be used with cpmtools (or cpmtools w/libdsk).
New CPMTOOLS definitions require the following stanzas:

diskdef title
seclen xxx #= Sectors xx,1024
tracks xx #= (Cylinders * Sides) = 80*2 = 160
sectrk xx #= Sectors 5,xxx
blocksize xxxx #= (128*(BLM+1)) = 2048
maxdir xxx #= (DRM+1) = 256
skew x #= may be 1 thru 6, or so
boottrk x #= SOFS or OFS = 2
#= 2.2, or 2, or 3 - NO COMMENT can be on last stanza
os x.x
end

It could be one of the JADE Definitions or another one, depending on the hardware on the system that wrote the Image.

#cpmtools Definition
# JAD1 Jade - SSDD 8" - 128 x 48
diskdef jad1
seclen 128
tracks 77
sectrk 48[/quote]
blocksize 2048
maxdir 64
skew 1
boottrk 2
os 2.2
end

#libdsk Definition
# libdsk data below

description = JAD1 Jade - SSDD 8" - 128 x 48
cylinders = 77
heads = 1
secsize = 128
sectors = 48
secbase = 1
datarate = ED

It could also be accessed with following Floppy Definition.

#cpmtools Definition
# A1 Generic CP/M - SSSD 8" - 128 x 26
diskdef a1
seclen 128
tracks 77
sectrk 26

end

#libdsk Definition

cylinders = 77
heads = 1
secsize = 128

datarate = HD

Or it may be another 8" - 26 x 128 Definition. More investigation and testing is required.

Using Hexedit in a Linux Terminal (Command Window) we can look at the HEX Data in JADEDD.RAW,
and locate the directory entries. The first entry is located at 0x2600. 0x2600 is 9728 Decimal.

cpmtools sometimes has problems with the first two tracks being a mixed variety of single & double density.
A way to skip the first two tracks is to define where the offset of the Directory is located. We already know
this is 9729. So, the following stanzas can be modified to point cpmtools at the Directory information:

..
..
skew 1
offset 9728
boottrk 0
# boottrk 2
os 2.2
end

After editing the diskdefs file for cpmtools, you have to also copy the updated diskdefs file to
/usr/local/share/diskdefs (in Linux)

Code: Select all: $sudo cp ~/path/to/cpmtools/diskdefs /usr/local/share/diskdefs

Now, you can try to access the directory listing from the Terminal.

Code: Select all: $cpmls -f a1 -D JADEDD.RAW $cpmls -f a1 -li JADEDD.RAW

Code: Select all: $cpmls -f a1 -D JADEDD.RAW

This gives the listing in order of the directory entries, which is nice to have.

The next thing to do is to extract a .TXT, .ASM, .M80, or .SUB file to see if they are SANE.
If the definition isn't correct, there will be all kinds of mixed data in the ASCII extracted file.

More information on the cpmls command can be found with this command:

Code: Select all: $man cpmls $man cpmcp

I chose bioslder.asm to extract with cpmls: (be sure to notice the PERIOD at the end of some commands)

Code: Select all: $pwd $~/IMDs/jadedd $cpmcp -f a1 JADEDD.RAW 0:bioslder.asm .

Which looks SANE. So, now all .asm files need to be extracted.

Code: Select all: $cpmcp -f a1 JADEDD.RAW 0:*.asm .

All the ASCII files also appear SANE.

Code: Select all: $cpmcp -f a1 JADEDD.RAW 0:* . $cpmcp -f a1 JADEDD.RAW 1:*.asm . $cpmcp -f a1 JADEDD.RAW 2:*.asm .

Another way you can access the data is to modify the HEX DATA so it is in a standard
layout. In the HEX bytes below it's easy to see that Track 1, Side 0 is an odd format
for the floppy. Those two tracks are the boot information, and we really don't need
that, because we are after the data on the Images versus the boot information.

0/0 500 kbps SD 26x128
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

2/0 500 kbps SD 26x128
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
D DE5DE5D00D D D DE5DE5D00D D D DE5DE5D00D D D D DE5D00D D D D

Copying the information we need to work with gets:

0/0 500 kbps SD 26x128 = 3328 = 0x0D00 = Track 0, Side 0 = 3328

1/0 500 kbps DD 50x128 = 6400 = 0x1900 = Track 1, Side 0 = 3328 + 6400 = 9728 = 0x2600 for start of Track 2

2/0 500 kbps SD 26x128 = 3328 = 0x0D00 = Track 2, Side 0

What we want to do is remove some of the HEX bytes to get Track 1, Side 0 to be 3328 in size, to match Track 0, Side 0.

3328 + 3328 = 6656 = 0x1A00
0x2600 - 0x1A00 = 0xC00 = 3072 Bytes need to be removed from the Image.

The Linux dd command can easily edit/splice files.
https://www.rationallyparanoid.com/articles/dd-hex-editor.html

Code: Select all: $dd if=JADDED.RAW skip=03072 count=256256 bs=1 of=LKJADEDD.RAW conv=notrunc

Now, LKJADEDD.RAW has Track 0, Side 0 and Track 1, Side 0 the same size, but the file length is reduced.
That isn't a problem as we are after the data files in the Image. We just need to refine the A1 definition
to point at the directory location.

Code: Select all: $hexedit LKJADEDD.RAW shows the Directory at 0x1A00 = 6656

UPDATE 05-18-2018

I've just downloaded some ACORN .DSD ( .SSD) files, and cpmtools is having problems accessing the images. How I proceed?
How do I get a good Directory Listing, and extract good files?

Code: Select all: cpm1.dsd cpm2.dsd cpm3.dsd cpm4.dsd cpm5.dsd cpm6.dsd cpm7.dsd ciscobol.dsd CPM_Utilities_Disc.dsd Basic_Program_Disc.dsd CIS_Cobol_Program_Disc.dsd

The *.DSD (.SSD) images interleaved Cylinders and heads. CHS The proper way to convert these files
is to use OMNIDISK or the ZIP file (CPMUTILS.ZIP) to change the Interleave back to HCS.

I used my DOS Computer and these commands from within Omnidisk:

Code: Select all: *DRIVE 0 *ORDER CHS *IMAGE CPM1.DSD CHS *BACKUP * CPM1.IMG HCS

I did this for all of these *.DSD files.

409600 Apr 1 2006 CIS_Cobol_Program_Disc.dsd (renamed to CISCOBOL.DSD)
409600 Apr 1 2006 Basic_Program_Disc.dsd (renamed to BASICPRG.DSD)
409600 Apr 1 2006 CPM_Utilities_Disc.dsd (renamed to UTILS.DSD)
409600 Apr 1 2006 cpm7.dsd
409600 Apr 1 2006 cpm6.dsd
409600 Apr 1 2006 cpm5.dsd
409600 Apr 1 2006 cpm4.dsd
409600 Apr 1 2006 cpm3.dsd
409600 Apr 1 2006 cpm2.dsd
409600 Apr 1 2006 cpm1.dsd

409600 May 8 05:01 BASICPRG.IMG
409600 May 8 05:00 CISCOBOL.IMG
409600 May 8 04:59 UTILS.IMG
409600 May 8 04:59 CPM7.IMG
409600 May 8 04:58 CPM6.IMG
409600 May 8 04:58 CPM5.IMG
409600 May 8 04:57 CPM4.IMG
409600 May 8 04:56 CPM3.IMG
409600 May 8 04:56 CPM2.IMG
409600 May 8 04:55 CPM1.IMG

Now, the CPM1.IMG compares EXACTLY with the old Acorn CPM1.IMG file I had saved on my Hard drive.

But, I can't get cpmtools to extract a proper file. I've looked at my Definitions and tried lots of
different settings.

Code: Select all: # ACN1 Acorn CP/M on Acorn Z80 second processor. - 256 x 10 diskdef acn1 seclen 256 tracks 160 sectrk 10 secbase 0 blocksize 2048 maxdir 128 skew 1 boottrk 3 os 2.2 end # libdsk data below [acn1] description = ACN1 Acorn CP/M on Acorn Z80 second processor. - 256 x 10 sides = outback cylinders = 160 heads = 2 secsize = 256 sectors = 10 secbase = 0 datarate = SD # ACN2 Acorn CP/M on Acorn Z80 second processor (Alternate). - 256 x 10 diskdef acn2 seclen 256 tracks 160 sectrk 10 secbase 0 blocksize 2048 maxdir 128 skew 1 boottrk 3 os 2.2 end # libdsk data below [acn2] description = ACN2 Acorn CP/M on Acorn Z80 second processor (Alternate). - 256 x 10 sides = outback cylinders = 160 heads = 2 secsize = 256 sectors = 10 secbase = 0 datarate = SD # ACN3 Sloger DDCPM on Acorn Z80 second processor. - 512 x 10 diskdef acn3 seclen 512 tracks 160 sectrk 10 secbase 0 blocksize 4096 maxdir 256 skew 2 boottrk 3 os 2.2 end # libdsk data below [acn3] description = ACN3 Sloger DDCPM on Acorn Z80 second processor. - 512 x 10 sides = outback cylinders = 160 heads = 2 secsize = 512 sectors = 10 secbase = 0 datarate = DD # ACN4 Sloger DDCPM on Acorn Z80 second processor (alternate). - 512 x 10 diskdef acn4 seclen 512 tracks 160 sectrk 10 secbase 0 blocksize 4096 maxdir 256 skew 2 boottrk 3 os 2.2 end # libdsk data below [acn4] description = ACN4 Sloger DDCPM on Acorn Z80 second processor (alternate). - 512 x 10 sides = outback cylinders = 160 heads = 2 secsize = 512 sectors = 10 secbase = 0 datarate = DD

acornsd Definition has to be modified for location of directory:

Code: Select all: diskdef acornsd seclen 256 tracks 160 sides outback #= Order of Cylinders sectrk 10 blocksize 2048 maxdir 128 datarate DD fm YES skewtab 0,1,4,5,8,9,2,3,6,7 secbase 0 #skew 3 #0x1E00 is where directory is located. 7680 offset to directory. offset 7680 boottrk 0 #= 2, 2.2, or 3 (NO comment on next line) os 2.2 end

I can get a good directory listing.

Code: Select all: cpmls -f acornsd -D CISCOBOL.IMG

UPDATE 06-07-2018

I've just located a good URL for TIKI .dsk Images.

These disk images are in the .dsk format and were created with ANADISK for MS-DOS by using the sector dump
feature to dump the sectors. The .dsk files I've downloaded are:

204800 Jan 25 2001 kpm11.dsk
204800 Jan 10 2001 kpm115.dsk
204800 Sep 14 2003 kpm117.dsk

409600 Jan 28 2001 tiko208r-400k.dsk
204800 Jan 28 2001 tiko208r-200k.dsk

I tried RAWRITE and other utilities, but couldn't get the Images written with my DOS 7.1 Computer. So, I tried creating
IMD files with the Imagedisk Utility BIN2IMD from DOSBox on my Linux Laptop.

REF: http://www.vcfed.org/forum/showthread.php?49761-Old-PC-Floppy-images/page2

RAW to .IMD format:
You can convert raw sector images to ImageDisk using the following commands:

160k raw to imd: (163,840 bytes)
BIN2IMD <image.img> <image.imd> DM=5 N=40 SS=512 SM=1-8 /1

180k raw to imd: (184,320 bytes)
BIN2IMD <image.img> <image.imd> DM=5 N=40 SS=512 SM=1-9 /1

320k raw to imd: (327,680 bytes)
BIN2IMD <image.img> <image.imd> DM=5 N=40 SS=512 SM=1-8 /2

360k raw to imd: (368,640 bytes)
BIN2IMD <image.img> <image.imd> DM=5 N=40 SS=512 SM=1-9 /2

1.2mb raw to imd: (1,228,800 bytes)
BIN2IMD <image.img> <image.imd> DM=3 N=80 SS=512 SM=1-15 /2

720k (3.5") raw to imd: (737,280 bytes)
BIN2IMD <image.img> <image.imd> DM=5 N=80 SS=512 SM=1-9 /2

1.44mb raw to imd: (1,474,560 bytes)
BIN2IMD <image.img> <image.imd> DM=3 N=80 SS=512 SM=1-18 /2

Create some test *.IMD files to write with IMD:

Code: Select all: BIN2IMD KPM11.DSK KPM11.IMD DM=5 N=40 SS=512 SM=1-10 /1 BIN2IMD KPM115.DSK KPM115.IMD DM=5 N=40 SS=512 SM=1-10 /1 BIN2IMD KPM117.DSK KPM115.IMD DM=5 N=40 SS=512 SM=1-10 /1 BIN2IMD TIK200.DSK TIK200.IMD DM=5 N=40 SS=512 SM=1-10 /1 BIN2IMD TIK400.DSK TIK400.IMD DM=5 N=40 SS=512 SM=1-10 /2 BIN2IMD TIKOS20.DSK TIKOS20.IMD DM=5 N=40 SS=512 SM=1-10 /2 BIN2IMD TKJER401.DSK TKJER401.IMD DM=5 N=40 SS=512 SM=1-10 /2 BIN2IMD WCSYS.DSK WCSYS.IMD DM=5 N=80 SS=512 SM=1-10 /2

Create .RAW Images with IMDU (to VERIFY with .DSK Images)

Code: Select all: IMDU KPM11.IMD KPM11.RAW /B /E /D > KPM11.TXT IMDU KPM115.IMD KPM115.RAW /B /E /D > KPM115.TXT IMDU KPM117.IMD KPM115.RAW /B /E /D > KPM117.TXT IMDU TIK200.IMD TIK200.RAW /B /E /D > TIK200.TXT IMDU TIK400.IMD TIK400.RAW /B /E /D > TIK400.TXT IMDU TIKOS20.IMD TIKOS20.RAW /B /E /D > TIKOS20.TXT IMDU TKJER401.IMD TKJER401.RAW /B /E /D > TKJER401.TXT IMDU WCSYS.IMD WCSYS.RAW /B /E /D > WCSYS.TXT

The KPM11.TXT file contains information on the Image:

Notice the 40 tracks and 10 Sectors of 512 Bytes.

Code: Select all: $ls -alt *.RAW

Code: Select all: 204800 Jun 1 18:10 KPM11.RAW 204800 Jun 1 18:11 KPM115.RAW 204800 Jun 1 18:10 KPM117.RAW 204800 Jun 1 12:40 TIK200.RAW 409600 Jun 1 12:51 TIK400.RAW 409600 Jun 1 12:51 TIKOS20.RAW 409600 Jun 1 18:11 TKJER401.RAW 819200 Jun 1 18:12 WCSYS.RAW

The .RAW images can be accessed with cpmtools with the proper definitions.

New CPMTOOLS definitions require the following information:
diskdef title
seclen xxx #= Sectors xx,1024
tracks xx #= (Cylinders * Sides) = 80*2 = 160
sectrk xx #= Sectors 5,xxx
blocksize xxxx #= (128*(BLM+1)) = 2048
maxdir xxx #= (DRM+1) = 256
skew x #= may be 1 thru 6, or so
boottrk x #= OFS = 2
os x.x #= 2.2, or 2, or 3
end

New LIBDSK definitions require the following information:
[title]
description = DESC The description of the format as shown by (for example) dskform–help.
sidedness =TREATMENT How a double-sided disk is handled. This can either be alt
(sides alternate – used by most PC-hosted operating systems),
outback (use side 0 tracks 0-79, then side 1 tracks 79-0 – used
by 144FEAT CP/M disks), or outout (use side 0 tracks 0-79, then
side 1 tracks 0-79 – used by some Acorn formats). If the disk is
single-sided, this parameter can be omitted.
cylinders = COUNT Sets the number of cylinders (usually 40 or 80).
heads = COUNT Sets the number of heads (usually 1 or 2 for single- or double- sided).
sectors = COUNT Sets the number of sectors per track.
secbase = NUMBER Sets the first sector number on a track. Usually 1; some Acorn formats use 0.
secsize = COUNT Sets the size of a sector in bytes. This should be a power of 2.
datarate = VALUE Sets the rate at which the disk should be accessed. This is: HD, DD, SD or ED.
rwgap = VALUE Sets the read/write gap.
fmtgap = VALUE Sets the format gap.
fm = Y or N Sets the recording mode - Y for FM, N for MFM.
multitrack = Y or N Sets multitrack mode.
skipdeleted = Y or N Sets whether to skip deleted data.

The LIBDSK Data rate will be one of:
RATE_HD, /* Rate for High-density disc - 1.2Mb in 5.25" 96 tpi drive, or 1.44Mb in 3.5" 96 tpi drive */
RATE_DD, /* Rate for Double-density disc - 360k in 5.25" 48 tpi drive, or 720K in 3.5" 48 tpi drive */
RATE_SD, /* Rate for Double-density disc - 180k in 5.25" 48 tpi drive, or 360k in 3.5" 48 tpi drive */

KOPIERING AV 200K DISKETTER

De fleste programmer leveres p} 200K disketter. Av praktiske grunner
anbefaler vi at disse kopieres over til 400K disketter.
For } kopiere fra 200K disketter til 400K disketter g}r en fram
p} f|lgende m}te:

Med en disketstasjon:

* Formater en ny 400K diskett ved hjelp av NYPLATE (Valg M i menyen).

* Sett inn TIKO KJERNE disketten. Tast A for } avslutte menyen.

* Skriv: Install tikoab.sys Trykk RETUR-tasten.

* Velg G (oppdater hukomelsen) i INSTALL-menyen. Trykk RETUR to ganger.

* Avslutt programmet med X

* N} er stasjonen midlertidig instalert slik at maskinen n}r du har
tegnet a>> venter } finne en 400K diskett, mens den n}r du har tegnet
b>> p} skjermen venter } finne en 200K diskett i diskettstasjonen.

* N}r skjermen viser klartegnet a>> skriver du: Kopi a:=b:*.* -W <RETUR>

* Det er viktig } skrive -w til slutt. Det lar deg stoppe og bytte
mellom 200k og 400K disketten n}r du kopierer.

* Du blir spurt om } sette inn fraplate. Sett inn 200K disketten du
skal kopiere fra og trykk <RETUR>

* Sett inn den formaterte 400K disketten og trykk <RETUR> n}r du blir
spurt om } sette inn tilplate.

* Slik fortsetter du helt til disketten er ferdig kopiert.

Hvis du har to diskettstasjoner kan du bruke oppskriften i APPENDIX A2
i INSTRUKSJONSBOK for TIKI-100. Bytt ut ordet 800K med 400K.

Thanks.
