CHM has an Amdahl 470 and a Siemens 4004 (RCA Spectra).

There were lots of people who built byte-oriented machines with instruction
sets similar to the 360 and I know there are people who have Interdata, and
Univac 9x00 machines. Memorex built a 16 bit 360 like machine, and I have some
docs and software for that.

The artifacts of these sorts of machines haven't been preserved very well. Same
for Burroughs, Univac and NCR (business as opposed to scientific computers).
