The display i/f board... looks like all TTL, some RAM, and one EPROM
The connection to the monitor is an internal DB25 (for power and signals).

Not finding any clear indication of dates from
the boards. Some of the
chips if I'm reading them correct look date coded in 1982.
CPU board has 8085 cpu, a D3242 ? HM4864P-2 (16 of them)
Sort of a yawn so far. the D3242 part is an Intel address
mux/refresh counter and the 4864's are 64x1 DRAMs (128K system).
What does the unit use for a CRTC and FDC?
Cheers,
