Abstract
PURPOSE: To allow a home computer equipped with a timer to execute a program at the preset time.
CONSTITUTION: A clock pulse from oscillator 6 is counted by counter 7 and then divided before being inputted to register 2 via OR gate 9. Into register 3, the time at which the program of the computer is to be executed is set previously. On detecting the coincidence between contents of both registers, comparator 8 outpus an interruption signal to the computer. The content of register 3 can be set by ten-key 1 with switch 9 made at the B side.
