In the upcoming days, I'll be able to send you a description of the hardware -- Is there any documentation with the system? The System 80 was the last descendent of the Univac 9000 series, a 360-ish 32 bit architecture. I had a little exposure to a 9300, which was very much like a 360 with the exception of I/O I'm sure all of this evolved as did the 360 to 370 over 20+ years.
