On a related note, but a separate question, does
anyone actually have
the wiring schedule for a PDP-8/S backplane? A long time ago, I was
willing to start constructing flip chip modules that made up a PDP-8,
but I could never find the wiring schedule for the backplane online so
that I could truly build the computer.
I think if you are building a replica is to design your own Flip/Chips
and build a clean design from scratch. A PDP-8/S does not look that
impressive, I know I seen one in the flesh once,as compared to a
PDP-8/e. If you go with 20 I/O pins, (and sneaky pcb pinout )a simple
GAL (SMT) could make up a generic card and be re-programmed for
what ever logic you want.
