Hello all,
I asked this question in a different thread but it may have been bogged
down in other discussion so I figured it was worth asking again.
What was the hardware configuration of the 11/45 that Research used to
implement early UNIX? This would be circa late 1972/earlty 1973. I have
found numerous references to it being an early production 11/45, and I
assume that it had an RK05, but I cannot find any details about things like
memory size and other peripherals.
Since the only extant sources are for V1, which was as I understand only
run on a singular 11/20, and V5 by which time UNIX had spread it doesn't
seem possible to infer a hardware configuration from existing code.
