Abstract

The circuit shown here permits absolute positioning of X and Y counters used in conjunction with a joystick, thumbwheels or other positioning mechanism for a cursor on a graphic display screen. This circuit is a modification to the single-shot control for joystick described in the IBM Technical Disclosure Bulletin 21, 3720-3721 (February 1979).
