Due to the volume of responses I've received on the problems of my friend's
flakey floppy drive wierdness, I'm posting this status report on the
latest discoveries.  Just to clear a couple of things up, we have tried
a number of different blank disks and were able to use the original
disks without problem, so we were convinced that the disks we were using
were fine.  We had also verified that the drive itself wasn't the problem
since the same symptoms were observed on a known good 1010 attached to
the A500.  So we were suspicious that the problem was due to the floppy
I/O hardware.   Looks like that was wrong also though due to this weekend's
discovery.

Since my friend was never able to get the expansion memory board's clock
to ever be recognized as existing on bootup, he removed the expansion
board itself.  When he did this, he found that he was then able to use
the floppy drive just fine.  When the board was installed, the system
reported on workbench the full amount of memory, but something must not
be cool with the expansion board or the connection from the A500
motherboard.  In any case, he's trying to convince the dealer to give him
another expansion board to see if that will work this time.

Thanks to all for your replies.
