Abstract
An interface circuit for use between a control point equipped with joysticks and switches and a standard serial input port of a personal type computer. The interface circuitry includes an analog to digital converter, a microcontroller operated as a reformatter for signals received from the analog to digital converter and a transistorized converter circuit connected between the output of the microcontroller and the serial input of the computer to convert the voltage level of signals output from the microcontroller in reformatted form.
