From article <4820@louie.udel.EDU:, by 24847843%WSUVM1.BITNET@cunyvm.cuny.edu (Shawn Clabough):
: 
: Does anyone know if there is a newer version since revision 3 of the PA?
: I have that revision (3) and I was wondering if the problems might have
: been solved with a newer revision.
: 
	The revision 3 boards are the current boards for the 2000. We found
a layout problem on that board that was causing intermittent problems on
some 2000s when a math chip was installed. The solution was to re-route
that particular trace on the other side of the board, away from some other
traces. 
	The revision 4 boards are what we're currently shipping for the 500.
It has some extra circuitry to handle the differences in the 500s expansion
buss and internal architecture. If you are having seating problems on a 500,
look on the underside of the board and see if maybe there is a lead or two
that stick down too far. If one corner of the board is held up too high, you
could see that symptom. You might also check to see that that electrolytic
cap over by Agnus is laying over enough to give clearance.
	Give me (or Lilliann) a call if you still have problems. (BTW, I
didn't realize it made that much of a difference with Marauder II colors.
Maybe I'll have to give that as a speedup example! :) :) )
