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 :-)

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
manual, too.
At the
back of the main circuit board, just in front of where the ribbon
cable connects to it, there is a 14-pin chip with a label "1F" beside it.
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). 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.
