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

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

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.
