There was a company (forget the name and product
(eagle?)), which was
selling a board with an mc68000 emulated by am2903. Was faster than the
original.
That, in a convoluted way, has reminded me of a couple more 29xx-based
processors
The HP9845 Opt 200 High Speed Language Processor contains 4 2901s and a 2910
The HP98770 colour monitor contains a video processor with, IIRC, 3 2903s
on it.
And the Xerox Daybreak contains 4 2901-like things (maybe 7C901s) and a
custom sequencer chip.
