Can't you just load them into ram and run them from there?Rom is just non
writable memory.

Hi Mark,
It probably does not matter anymore unfortunately. I have a PDP-11 from
a Unimation PUMA robot, which has a 16x EPROM board in it but no power
supply. I was hoping to try running what was on them inside a
simulator. I started dumping them and realised that they have all been
erased before it was sent to me.
Of course I could have tried installing the card in my PDP-11/73 but I
thought there might have been an easier way with the simulator.
Never mind, thanks anyway.
Aaron.
