AFAIK there is nothing electrically or mechanically special about

For those that are considering moving floppy drives from one machine
to another, just remember that there are single and double-sided
versions of the TM-100 (various models from the TM-100-1 through the
TM-100-4). As long as you match up the model numbers (the TM-100-2A
is probably what you want for an ancient PC), the logo on the face
plate has no influence on what the controller does to the drive (i.e.
- there are _no_ electronic differences between an IBM-badged TM-100
and the same drive with a plain faceplate).
I only say that because I've seen single-sided TM-100s (TM-100-1A) in
CP/M machines. They should work with an IBM 5150 PC, but, naturally,
only as single-sided drives, at a nominal 180K under DOS 2.1 and newer
(9 sectors per track vs 8 sector "160K" disks in the earliest
examples).
Yes but then you can notch your diskettes and flip them.
However I did find three IBM marked FH Tandon TM-100 5
1/4" disk
drives last week :-)
Are those special? I think my TRS-80 Model III has two of them.
