How do I know which SIMM to pull?

which SIMM I needed to replace. Within an hour I started getting
messages back from the gurus of this group. Amazing.
Basically, the answer was right in front of me... the message in the
console tole me that...
> bad module/chip at: U676 <<======== ?
The Uxxx numbers are silk-screened right onto the mother board itself.
More than one of the people listed below went so far as to open their
FE manuals and such, and give me very clear directions on how to find it
(thank you very much). A special thanks to Jens Fischer, who helped
me understand how the banks are arranged, which let me know if this
was a 1 or 4 Mb SIMM.
Since the machine actually panic'd out a few times, I popped the lid,
pulled the SIMM, did the erasor trick to the contacts, dusted things off
in general, and put it back together. No sign of problems since then.
My fingers remain crossed.
Other bits of wisdom worth repeating...
