 I don't recall offhand whether -60
RAM works in a -90. I *do* recall that the
order of installation in a -90
is not obvious (i.e. it is not either of
"every other slot starting at either end"
or "any contiguous block of four slots").

It is ABCD if you actually pay very close
attention to where ABCD actually are
(and can see past the dust).
If you were adding eight identical SIMMs
(e.g. 8 of 16MB) then this cannot have been
your problem. But if you were adding 4 new
SIMMs *or* mixing 4 16MB SIMMs with
4 smaller SIMMs, then it may well have been
what was happening.

 Your problem may have been=20
something completely different
(I missed the start of the thread).
