With a background in creating arcade games such as "Food Fight", GCC designed the new system with a graphics architecture similar to arcade machines of the time. Powering the system is a slightly customized 6502 processor, the Atari SALLY (sometimes described as a "6502C"), running at 1.79 MHz. By some measures the 7800 is more powerful, and by others less, than Nintendo's 1983 NES. It uses the 2600's Television Interface Adaptor chip, with the same restrictions, for generating two-channels of audio.
