Can static RAM can't cope with these kinds of
speeds? Presumably cache
chips pulled from old PC motherboards would cope happily, even if old
80's parts wouldn't.
Easily and cheaply gotten SRAM should easily be able to cope with speeds
like 1 megabit a second or even 1 megabyte a second or even 10 megabytes
a second, or even more.
It's probably still beyond my abilities to design
something that'd
work :-) But on the surface it doesn't sound *that* complicated for
someone who's used to designing digital circuits.
But don't look at me. I just look at designs, I don't really make them.
