Hello everyone,
I recently got a DEC PRO 350. It suffering from a lack of RAM since two
of its three memory boards are defective (one of the small ones that
plug into the mainboard and one that goes into the extension cage and
seems to carry its own DRAM controller in logic).
I first wanted to take a look at the small one but I can't even find any
info on the ICs used:
JAPAN 8304U
21-18470-01
That's a DEC house number...
Hoe many pins do these chips have? If 16, I'll bet they're a common DRAM.
Do you know the capacity of the board? If so, you should be able to work
out what chips would have been used (e.g. if it's a 64K word board, and
there are 16 chips, I'd guess they were 4164s).
