Didn't the GI CP1600 have an external line that, if
activated, would
inhibit P-counter increment? I don't know if anyone ever used it for
anything.

My, what a remarkable memory you have: pin 40, /PCIT (Program Counter Inhibit),
also used to output a pulse on execution of an SIN (software interrupt) instruction,
apparently used mainly by the control console.
