I could, but the point is to run 1972 Unix on machine
that was around
in 1972, even if I have emulate things like the RF disks.
Except that the MEM11
wasn't around in 1972. going to be, by necessity, some compromises made.
Witness the previous
Remaking the missing hardware following the original designs and using technology
close to the original is one thing. A functional emulator is something quite different.
The 11/20 in 1972 did not (AFAIK) use any programmable logic chips, for example.
discussion on
the IBM 1620 where the core memory has been replaced with a modern
equivalent in order
to allow it to work. I view this in a similar vein.
So do I.
