Many thanks to John, Dzung, Mark, and Derrick for their helpful input to my
flex drive problem.  Upon their advice, I checked power, MMU and GLUE chips
and found all were OK.  The computer still won't recognize the floppy drive
during powerup (or any time, for that matter).  I hooked up an external drive
(genuine Atari), which went unrecognized, except for its existence (i.e.,
trying to format drive B did not result in the prompt to insert a disk as if
only one drive existed).  That shoots the cabling theory as well.  I'm left
with the floppy controller chip (WD1772).  I don't want to mess around with my
one working ST, so I need a source for this chip.  Any suggestions?

P.S.  I did listen very carefully and, yes, the drive DOES spin when accessed
and the light DOES come on, but that's all.
