IBM 6360 8 inch floppy drive

[Al Kossow]

The thread on comp.os.cpm is "Displaywriter and CP/M 86"

-- exerpts

Both of those .TD0 files were created on a HD 3.5" Floppy (Single Sided)
with Teledisk Ver 2.15

01.IMD = 01.TD0
IMageDisk Utility 1.18 / Mar 07 2012
IMD TD 1.5 3.5 HD MFM S-step, 1 sides ADV 30/03/2005 23:48:57

DRI Disk with odd CP/M-86 format

 0/0 500 kbps SD  26x128
 1/0 500 kbps SD  15x256
 6/0 500 kbps DD  8x1024
77 tracks(77/0), 669 sectors (225 Compressed)

21.IMD = 21.TD0
IMageDisk Utility 1.18 / Mar 07 2012
IMD TD 1.5 3.5 HD MFM S-step, 1 sides ADV 31/03/2005 22:50:32

Unknown CP/M-86 disk image

 0/0 500 kbps SD  26x128
 1/0 500 kbps SD  15x256
 6/0 500 kbps DD  8x1024
77 tracks(77/0), 669 sectors (58 Compressed, 1 Bad)

I've conjured up a cpmtools definition for a correct directory listing of both TD0 files.

# COM8X  Compupro (Viasyn) 8/16 - SSDD 8" - 1024 x 8
diskdef com8x
  seclen 1024
  tracks 77
  sectrk 8
  blocksize 2048
  maxdir 128
  skew 3
  offset 22528
  boottrk 0
end

It seems to work correctly.
