What programs or operating sytems require non volatile core?
Did DEC have any BOOTSTRAP programs in prom for the 8?
A small prom and regular slow mos memory may be the solution.
Ben.
I?m trying to make a look and feel reproduction PDP-8/e.
So the memory characteristics need to be as close as possible.
An original ( and I do have one) and the copy when placed side by side should run in
sync.
When executing he same code ? What code I couldn?t care.
