Tony, wouldn't one need a (somewhat :) clean room for such
stuff, and (for heads) optical gear and all that??

I still believe (as I just explained in detail to another list
member ;-) that such a QUnibus board design should be based on
a micro only- the "classic" design, where, if we really have
to (read: if the micro is no longer available..) can quickly
redesign it with another micro. I'd base it on an Intel
chip, *simply because* of their availability by scavenging
old PC's.
