The APF TV Fun is a series of early Pong clone consoles manufactured by APF Electronics Inc. and built in Japan starting in 1976. The systems were among the first built on the General Instrument 'Pong on a chip', the AY-3-8500, that allowed many manufacturers to compete against the Atari home pong.The TV Fun package is the first excursion of APF into the video game market; APF was formerly a calculator and other small electronics developer. It was sold at Sears under the name Hockey Jockari.
