Convert .DSK file to .IMD 8" 77x26x128

[ldkraemer]

Ragnrock,
I Don't know why It keeps defaulting to 300RPM and 300kbps. I kept changing the HxC settings
and trying to force it to 360 RPM and 500kbbs for the 8" image. I think I finally have it nailed
in the *.IMD file.

The *.DSK is really a *.RAW format and it shows the Image as 360 RPM and 500KBPS.

All the other files are TRASH. I wish there was an easy way to go delete them.

This *.IMD file should boot properly.

Larry, that one booted! and it formatted on imagedisk as 500k single density with having to mess with any settings so I think it's a winner.

Tarbell 48K CPM 2.2 auto-select ver of 01-29-82
on my Altair 8800B with Tarbell 2022 double density FDC, and serial ports modified to run at 10H, dual SA800 drives.

I suspect some of your other attempts also worked along with changes in settings I tried because there appears to be some intermittenancy with my hardware which I haven't figured out yet.

Thanks so much for your help and to the others who have helped including my TN friend.

Roger,
GREAT NEWS. Now, I am going to go back and get PNG's of the settings and
create a step by step of how to make one that works for SS/SD & SS/DD,
so anyone who comes across this later will have good information to follow.

I think the HxC software was resetting to it's best guess of 300kbps and 300 RPM,
but that wasn't correct. I should have loaded each *.IMD I created and double checked
vs assuming it was 250kbps & 360 RPM.

If you are reading this at a date later than Nov 6, 2025, DO NOT worry about downloading
any of the previous files that I posted. I assumed the HxC Software would keep the
same settings I had inserted into the LOAD RAW section when writing out a IMD Image.
It's my fault for not double checking the *.IMD IMAGE to make sure it wrote what I wanted.

So, here are step by step directions for creating Images that boot for SS/SD & SS/DD for the
Tarbell FDC.

Roger's Information about his computer:

I have an S100 8800B with UART at 10H, and a Tarbell 2022 DD FDC, with dual Shugart SA800 single-sided drives.

All hardware appears to work, and drive A seeks home and loads head trying to boot. So I need CPM boot media
- 8" 77x26x128 single sided. - normal stuff.

I have a working Imagedisk system with an 8" drive so if I could get a CPM 2.2 .IMD image file with a BIOS that matches
this SIO and FDC I could boot. Want SS/SD, don't care about double density.

I started with the two Tarbell *.DSK Images that are attached.
TARBELLSD-CPM22-SSSD-48K.DSK
TARBELLDD-CPM22-SSDD-48K.DSK

NOTE: These Images are labeled .DSK but are really .RAW Images, which are Sector Dumps.

Next step is to load the .RAW Images into the HxC Software by setting up the .RAW Parameters as shown
in the attached Step-1.png file. This will be a SS/SD IMAGE.

Once the .RAW file is loaded, Double check the settings as shown in Step2.png, Step-3.png, then Step4.png.

Now, the File is ready to be exported as shown in Step-5.png & Step-6.png, so EXPORT a *.IMD file that will boot.

For a SS/DD Image select the settings as shown in Step-7.png.

This should clear up and confusion about why HxC defaulted to the improper setting, which I did not double check.

The .DSK (really .RAW) images can be accessed with cpmtools built with libdsk for directory listings.

I left the exercise of building a SS/DD Image for y'all to follow! It should be easy enough with the above steps.

The TARBELLDD-CPM22-SSDD-48K.IMD file should boot.

Roger and Larry K - I was dealing with the same situation trying to get my CCS 2422 to boot with CompuPro hardware CPU-Z, 4x RAM16's and System Support 1 as the serial terminal plus a bonus 9511 math chip that came with it..
I have an 8" NEC 1165 drive dedicated as an imager via an Adaptec SCSI floppy controller on a DOS machine that can do mixed densities. I use a DOS usb driver to read my usb sticks from MSDOS to get it from my Windows internet box to the MSDOS box then write images with Imagedsk or files with 22DISK. I am working with 8" SSSD 128x26x77 to keep it simple. My goal is to eventually get a pair of 96 TPI 5.25" I have as boot media. I have two Gotek's that sit on a shelf. Emulation is not my interest for now. Hex editing binary images with HxD seems the easiest for now to try different boot code. I use Samdisk to convert IMD to RAW (binary) then Dunfield's BIN2IMD to convert back with these parameters: /1 N=77 SS=128 /U DM=0 SM=1-26. This method is working out good for now. /1 is single sided, N=77 number of tracks, SS=128 sector size, /U uncompressed, DM=0 mode 0, SM 1-26 is sector order.
Oh and I have the most success with writing single density floppies with Imagedisk by converting 250k to 500k. It could be because of the NEC drive or the floppy controller or media I'm using. I think DSK is the same as RAW. Just binary IMG.
I have two CompuPro 8" dual drives one on the CCS and one on my CompuPro 286 mother ship for a total of five 8" drives. I'm in floppy paradise ...

Roger,
While looking on Bitsavers I located some information on the TARBELL Floppy DIsk Controller. In that documentation
I located the Disk Parameter Block (DPB) for SS/SD, DS/SD, SS/DD, DS/DD. I conjured up definitions that should
work with these Floppy Types.

Theses haven't be tested yet, but should work.

#
#According to the printed documentation I have for 22DISK Version 1.39
#
#alt     SIDES specifies that first one side then the other is written/read
#              before the cylinder number is advanced.
#
#outback 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.
#
#outout  EAGLE same as CYLINDERS except both sides start at zero or outermost
#              track.
#
#        COLUMBIA same as CYLINDERS except tracks are sequential from side
#              0 to side 1 ie. 0 - 79 for a 40 track disk.
#
#        EVEN-ODD means side 0 contains even-numbered tracks and side 1
#              contains odd-numbered tracks. 
#
#        SKIP means skip the first Single Density Track
#
#diskdef title
#  seclen xxx        #= Sectors xx,1024
#  tracks xx         #= (Cylinders * Sides) = 80*2 = 160
#  sides alt         #= Order of Cylinders  = alt, outout, outback
#  sectrk xx         #= Sectors 5,xxx
#  blocksize xxxx    #= (128*(BLM+1)) = 1024, 2048, 4096, 8192
