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
There is a small logo that seems to indicate Hitachi as manufacturer
[1]. Google refused to find anything on these chips. Does anyone know a
few things about them? Pinout and timing would be a fair start...
Thanks
Sebastian
