Hello Everyone!
I would like to identify some mysterious old SIMMs:
- module P/N appears to be "PS 91/344J"
- 30 pin, single sided, 9 chips "SIEMENS HYB514100BJ-60"
- "MADE IN U.S.A." probably manufactured in 1994
I have failed to find explicit information about these chips,
but I'd guess they are 1Mx4 so 9 of them would make a nice
4MB module with ECC/parity.
What kind of machine could these have been made for?
Thanks,
Sab

No, the HYB514100 is 1x4M. So this would be a simple 4MB FPM DRAM
SIMM with partiy. This would probably fit thousands of different
systems of the time. Very common on 386 and 486 boxes, but even used
on some 286 ones.
