PDP-11/35 Original Configuration
Although the system had been modified and upgraded since, the original
configuration was still visible on
this table
on top of the CPU box. The paper has seen better days and some parts were
getting hard to read, so I figured I'd record the information here too.
It would appear that the system originally had a teletype or other 20mA
console as the M7800-YA doesn't support anything else. The MF11-UP would be
a 9-slot backplane for 32 Kbytes of core memory with parity (indicated by
the "P" designation and the M7259 module). I'm not entirely sure what the
MM11-UP means, but I suspect it refers to one individual 16 Kbyte memory
module, of which there'd be two.
