TRS-80 model 16. Like a Model 2, but with a 68K installed
in
addition. The Z80 still does the I/O and boots CP/M 2.2,
then one
boots CP/M 68K.
...but that's only 2 CPUs, albeit different and both used in
their
own right for user tasks.
Bill Godbout marketed a couple of dual Intel CPU boards as
well as
boards for various other processors (68K, etc.) in his
Compupro S-100
line.
