One easy solution...  Gentle lift the ST up about 4 inches and drop *sharply*
on the tabletop.  This actually works much better than it sounds.  The chip
sockets for most of the ST's, especially the old ones, were
absolutely the *CHEAPEST* ones that Atari could buy.  My ST used to exhibit many
of these symptoms, and I got fed up with it and brought it in to a de-solder
station and removed all of the sockets and replaced them with new, (and more
expensive ;-() sockets, and have had very little problems with it since.  It's
a little radical, but it sure fixed it up proper.

	Right quote, wrong conclusion...  I have both ACB-4000 and ACB-4000A
and they work *exactly* the same.  In fact, the only difference that I could
find is that the board layout is slightly different, and the mounting holes
in the 4000A match the mounting holes on the bottom of a 5.25 hard disk, where
the older 4000 board does not.  The way I would then read the above quote from
the ACB-4000 manual is that the 4000A is a (newer) replacement for the
4000 *OR* the 4010.  So, buy the 4000 if you "get a deal on it" (Time Line
has the 4000 in their ad for $60, but it's really a 4000A), otherwise buy
an OMTI (its faster ;-)).
