Abstract

PURPOSE:To simply reset a program to its normal state in case the program has a runaway by resetting a CPU for each operation of a changeover switch. CONSTITUTION:In a power supply ON state the output of a shift register 7, i.e., the chip selection signal is set at L, H and H respectively. Thus a 1st memory chip 6a where a program A corresponding to a 1st game is written is selected. Then the output of the register 7 is set at H, L and H with operation of a changeover switch 1. Then a 2nd memory chip 6b where a program corresponding to a 2nd game is written is selected. At the same time, a CPU 2 is reset and carries out the selected program B. Then a 2nd LED 5b is turned on in place of a 1st LED 5a.
