If you don't like the 810 (not 850) disk drive, why not just buy a new
one.  It's a h*** of a lot easier than building one, unless you are a
h/w masochist.  (Or so I gather, I don't hack on h/w.)   The new XF551
Atari drive would be a good choice.  Since you have an IBM / other computer
background (it seems), you should understand "true" double-sided floppy
drives.  (Some of us Atarians have gotten so used to flipping floppies,
we flipped out when we saw a drive that deals with the 2nd side of a non-
flipped floppy!  [Try saying that fast, over and over again :-])  But not
me, I have Percoms, and I never got into punching 2nd-side index holes...
