System Clock_ by Gerald McMullon The COP provides a system clock after each interrupt (50 times per second).The COP scans the keyboard and looks after the relays for the cassette motor as well as handling the VF display.Page zero stores 4 bytes, the current status of the clock in location 52H-55H (82-85 decimal). The clock…
