It does, and it both helps and hinders.
The part number is a 2Mb x 8 FP DRAM, and 8 of them make up the 16MB of
That part is great news (mainly for you, but it's nice to have a pic)
The bad news is that I had hoped I could simply replace the ICs on my
unit with 4Mb x 16 FP DRAMs, assuming that's how they did the 16MB unit,
but it does not appear that way.
I guess I could replicate the PCB, and try to find 8 of those DRAMs....
At least I have the connector
Are you interested in selling the unit? Do you want someone to test it?
Does anyone else know of a 4Mb x 16 variety that is FP DRAM?
