Searching for the Naked Milli from Computer Automation Inc., I found this Mini computer history site with some interesting photos including a Spiras-65 from 1969 (but mainly DEC computers, Interdata and the Kitchen computer).
16 bits. Octal keypad. There was even a 360-Simulator software for that.
I think this is not the complete computer but part of a cabinet set as shown in the brochure.
