I recently decided to upgrade my ZIP from 8/0 (that's right, 0)
to an 8/64. I did the modifications (I hope correctly), and bought 4
supposed 32x8 20ns SRAMs...
The board doesn't work now, no matter what mode it's in. I took
out the 64k two chips, and thought it'd work in 32k mode; nope. Same
thing, it didn't work in 32, 8, 16 or whatever. Therefore i'm pretty
tempted to just take the ZIP, find a car crusher, and put the ZIP in
there... but I wanted to ask if anyone knew what exact size the chips
were:
W2464AK-20
9216
Who knows what brand they are; the little logo is a globe w/ a "W" part-
ially in it.
Thanx.
