Front panel

The CONTINUE, STOP, SING INST, and SING STEP switches just pokes the RUN flip-flop. But START, EXAMINE/DEPOSIT (NEXT), and READ IN jumps to microcode. Larsbrinkhoff (talk) 19:07, 23 July 2023 (CEST)

Thanks! I had previously noticed that a lot of the PDP-11 front panels were run by microcode, but wasn't up for working out the details of the PDP-9 front panel. Jnc (talk) 19:33, 23 July 2023 (CEST)
