I've seen contradictory documentation; GURU specifically mentions PAL 
SIMMs only for the II, but it gives identical part numbers for 4MB 
SIMMS for II, IIx, IIcx, and IIci!

They were released very close to each other; but now that I think 
about it, I seem to remember that the very early IIx machines did 
have a problem with memory; could it be that there is a board rev on 
the IIx which fixed the problem and allowed standard SIMMs?  I'll 
have to rummage through my TechNotes and see if that turns up...
