   Usually
there's a set of jumpers, or sometimes a small DIL switch pack,
 which select one of four disk addresses.  They may be labelled DS0, DS1,
 DS2, DS3 or
 perhaps D1, D2, D3, D4.  D0=A and D1=B.  You just need to switch the jumper
 settings.  Even if they're not labeled, you should find that all but one of
 the jumpers (the drive select jumper) in one drive match the jumpers in the
 other drive (of the ame pair). 
 Unfortunately, Pete, very few of the full high floppy drive makers were
 considerate enough to mark them that way.  That pretty much came about
 when they went to Berg jumpers for selection. 
I dunno, I've got a few full-height CDC and Tandon drives that are marked.
 But, yes, sadly a lot of drives aren't, which is why I suggested comparing
each drive of a pair -- hopefully they're the same model.

Well, maybe. :-)
