ONE MORE KEYBOARD ROUTINE

PIRQQ
65470         FFBE

The "IRQ" in this location's name should tip you off to the fact that this is the interrupt routine for the keyboard. It debounces the keys, checks for CTRL-1 (pause) and sets SSFLAG accordingly (767), stores the key value in CH (764) and CH1 (754), and clears ATRACT (77).
