I believe that almost any of the non-EDO 30 pin SIMMS for older PCs will
work. Don't pay real money for them, though. There have to be boatloads of
them floating around uselesss at present.

You can, btw, use the PROM to locate the bad sim.

IIRC, 

test memory

or, also

setenv diag-mode on
setenv selftest-#megs 64
reset
