Harris RTX-2000 - Re: High performance coprocessor boards of the 80s and 90s

[dwight]

The RTX-2000 was an of shoot of the NC4000. Even at 10MHz, they could
out compute a 40MHz 80386.
One execution per clock cycle plus possibly using 3 16 bit busses in a single
cycle.
A 4MHz NC4000 could sort 1K 16 bit values in 19.7 milliseconds.

I hadn't even heard of that chip :/

Interestingly: "The RTX 2000 is specifically designed to execute the
Forth language"
