#'''Telstar Arcade''' (1977): Cartridge-based, triangular case includes light gun, steering wheel with gear shift, and paddles, one on each side. Each cartridge includes a customized MOS Technology MPS-7600 chip (one of these chips was the 004 used by the Gemini). The chip contained custom logic circuits driven by a basic processor which ran a very small program stored in ROM.
