If a uP-based design is what seems appropriate, I'm personally in
favor of something more in the 68000-family, but that's because I
used to _make_ 680x0-based Qbus and Unibus boards (and still have
all the old docs). I'd be not in favor of an Intel design
because the CPU chip is _not_ the only important chip on the
motherboard - the mobo chipset is as important as the CPU in how
a modern machine works.
