Although headquartered in New York City, Unisonic outsourced its manufacturing operations to various facilities in East Asia (especially in Hong Kong, South Korea, and Japan).

As was the case with most "Pong clones" of the 1970s, Unisonic's Sportsman and Tournament consoles were driven by General Instrument's AY-3-8500-001, an integrated circuit containing seven video games.

The Unisonic consoles models not featuring a light gun offered a subset of these, consisting of four games: Practice, Squash, Hockey, and Tennis.

[4] Like the Mattel Intellivision, which is based on the more powerful General Instrument Gimini "Full Range 8900" reference design, the Champion 2711 is built around the 16-bit CP-1610 CPU.

Three of these cartridges contain additional card games, including variations on Poker, Mastermind and Concentration; the fourth PAC is an edutainment title called Arithmetic Primer.
