TPDD1 or TPDD2? The TPDD1 uses single density disks and TPPD2 I believe
used double density disks (not 100% sure since I only have a TPPD1). But
in the specs the TPPD1 reads/writes 40 tracks, and the TPDD2
reads/writes 80 tracks.

I don't think that's the issue as the drive responds to commands, and
I can see the head move. When trying to format a blank disk, it
actually goes through the motions, and gets to the last track, before
it fails.

I/O Error generally means the drive is not being seen on the
serial port. Does the serial port on the machine work? Can you
check it out make sure it is working? Link to a PC and use TELECOM
to a terminal program or try the new mcomm out.
Could be a bad TPDD cable I had problems with mine it was not
making good contact into the drive, I had to have it just in the
right position to work. I stopped using it after that :)

Well, I have REX, with TS-DOS, and also tried the
installation/bootup procedure from the manual. Didn't work either
way - I/O Error. I looked over the board, and don't see anything
obvious. Everything cleaned, etc.
My "big score" with a DVI, TPDD, and M100 has had an issue with
every single component... At least it came with a ton of cables,
manuals, and disks!
Unless somebody can suggest anything else I can try, I'm giving up
on the TPDD for now, too many things I'm working on, including
getting the drive in the DVI to work.

The "M100SIG" archive contains a few programs just for dealing
with the incompatibility of different dosses. There is at
least one or two programs just for loading and unloading the
dvi dos and a tpdd dos so you can switch between them without
actually wiping and reinstalling each time.
There is (on p. 7 of the TPDD2 Manual) a cryptic related
reference that the utility disk can’t be used with a
computer in conjunction with the DVI, so maybe these can’t
all be used at once,
