Wow, I'm amazed someone still has this. The ad I have, says specify
H-17/37/47 and HDOS or CP/M.

Mine is in a box, not sure of it's entire history, but I need to
inventory a bunch of equipment I just received before I start
experimenting with the board.

I think the only difference is that those are double-sided. I'm pretty
sure I've used a TM100-2A with the H17 and without any changes (unless
the previous owners made a change to it) and it worked as a
single-sided drive. There was also an improved CP/M bios  (bios-80 I
think) that allowed the H17 to work with the H17-4 drives, that bios
would probably also work with your drives and allow you to have 200K
per disk. I have a working copy of the bios-80 and will try to make an
image of it (my 'dos' machine was having some issues, so hopefully
I'll get that one working soon).
