In fact, this discussion has prodded me into doing
something I've put off
for a long time - strip some PCBs I found with 8ns CMOS static RAMs, 128Kx8.
They are surface mount and the small geometries are a real challenge for my
twisted fingers and bifocal eyes. But I have a project that needs fast
memory and the weekend is free.)
I haven't yet tried to salvage any surface-mount chips, yet, though I do
have a board here with a few transistors that are tempting me.
8 ns?! That's _fast_. What if you don't mind my asking are you doing that
needs those kinds of speeds? I'm used to thinking of access times in numbers
that are three digits long. :-) Some cache I snagged out of a defunct 486
board is about the fastest I've managed to salvage yet, and it oughta really
do just fine with a z80 or something, no wait states there!
