A fairly familiar joystick design for the IBM PCjr system. The IBM PCjr (read "PC junior") was IBM's first attempt to enter the market for relatively inexpensive educational and home-use personal computers. Two joystick ports were built into the PCjr, evidence of IBM's goal for marketing the PCjr as a home-friendly machine. Other than the Tandy 1000 and Amstrad IBM PC compatible lines a few years later, the dual built-in joystick ports introduced by the PCjr never became standard on IBM PC compatibles, and haven't been seen since. Also, in addition to the joystick ports having a different connector than used on the "game adapter" ISA card for PC compatibles, they required joysticks that had a different electrical resistance range in their X/Y access controllers, necessitating the use of PCjr-specific joysticks (or generic joysticks that had a dual-mode switch).
