Outrageous overkill. What's that, 10ns memory? What's the 8's
memory cycle time?? ;-)

I'd probably do something like what the SBC-6120 does... use some typical 486
motherboard cache SRAM. Cheap, and relatively easy to find. :) If you use 2167's ( 16k x 1 ) ram's
you can have 16k of memory ( 12 chips ) for
about $25 not counting glue logic and other stuff.
Why not use a pair of 62256s?
32Kx16 and ignore 4 bits. It'd even be
easy to use a Dallas DS1210 or something like it to provide battery
backup. You'd end up with one or two chips to do 32k x
12.
