 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
manual, too.

 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 :-)
