In 1978 Atari was working on a new chip set for an all new high end video game system. Ray Kassar became the new CEO of Atari and decided that Atari should produce a line of computers to compete against Apple in the home computer field. It was decided that the new chip set was to be "frozen" and used only for the new computer systems. Atari's all new computer division was born. Atari would introduce a new line of personal computers based around the MOS 6502 8 bit Processor. Using the new graphics/audio chip set the computer would come packaged with graphics and sound never before seen in a personal computer system. Capable of producing up to 128 colors using the CTIA chip (Colleen Television Interface Adapter) and later updated to 256 colors using a GTIA chip (General Television Interface Adapter) and with a maximum resolution of 320 X 192 the new line of Atari computer systems would have spectacular graphics for a system released in 1979. The Atari 800 case was designed by Kevin McKinsey of Atari's industrial design group, he wanted to give the Atari computers a warm familiar and friendly look. The new Atari 400 and 800 computers would look very similar to a standard home typewriter. The Atari 400 and 800 got their number designations from their original memory configurations which were 4K for the 400 and 8K for the 800. Also the Atari 400 and 800 were nicknamed after some very well endowed secretaries named Candy and Colleen.
