Any technical reason you used Teledisk instead of

Teledisk do something with these disks that ImageDisk cannot?
Imagedisk can't handle mixed sector sizes on a track.
I had forgotten about that. I vaguely remember running into that issue
working with some other HP disks, or .TDO images of HP disks. I
rebuilt a modified version of one of the ImageDisk tools from the
source code to work around the issue at the time. I don't remember the
details now.
Just found some notes on this from 5 years ago. At the time it was an
issue with
TD02IMD.COM. For example
TD02IMD.COM chokes on this disk
image with the "Cannot do mixed sector size within track" error:
http://www.hpmuseum.net/software/WORDSR80.TD0
I solved that at the time by modifying
TD02IMD.COM to allow it to
simply discard the other sized sectors, which after taking a look
didn't appear to be necessary.
