Acorn Computers made an odd machine consisting of a BBC micro with a 32016
second processor in a box. (It didn't run a unix-like OS, I'm afraid.) The
32016 was one of the CPUs that inspired the ARM, because its performance
was so terrible: it was not able to make good use of the available memory
bandwidth. (There wasn't a 68000 second processor because its interrupt
latency was too bad to drive the "tube" interface.)

Malin, Southeast Hebrides: Cyclonic 4 to 6. Slight or moderate in
southeast, moderate or rough in northwest. Showers. Good, occasionally
poor.
National couldn't get it together to produce
bug free chips or maybe
we'd all be running that, pretty nice architecture (in theory).
I've always wondered if a Nat Semi NS32016 based system running in a PC/AT
form factor had appeared that was priced like a PC/AT if that might have
had a chance.
