back of the main circuit board, just in front of where the ribbon

In drive A, there is an empty 16-pin socket beside it, with "2F" written
on the circuit board beside it. Drive B has something IN this socket - a
BLUE 16-pin chip.
Sounds a little like a Tandon drive, although those normally had the
jumper in location 1E (or at least the schematics I have show it there).
I believe it is a Tandon drive.
I am unable to view the main circuit boards of the drives because they're
in a metal box, but if 1E is directly in front of 2E, then yes, I believe
I'll find the jumpers there. I've found labeled photographs of a Tandon
drive in an old issue of 80 Micro.
It does sound like a Tandom TM100 (or of that series, anywy). I've got the
Allen hex - a
true hexagonal tip, which come in inch and metric sizes
This is the one I need. Possibly in metric sizes as none of the imperial
ones I have fit.
Much more likely to be Imperial, on American equipment. Some sets go up in
bigger steps than others, though; perhaps the one you need is just "missing".
I have a few sets like that :-)
