Would you actually need them this fast, or is this just based on the 
speed of static RAMs required for Transwarps/Zips at this speed?
I'm asking - I don't know any better.
These boards need to do a lot more than just access memory, and therefore
need really fast RAMs.

That's why I included the VOC. The VOC can put Super Hi-res on a //e.
