The Atari 8-bit computers, formally launched as the Atari Home Computer System, [4] are a series of home computers introduced by Atari, Inc., in 1979 with the Atari 400 and Atari 800. [5] The architecture is designed around the 8-bit MOS Technology 6502 CPU and three custom coprocessors which provide support for sprites , smooth ...

The Atari 800 has multiple special purpose co-processors for sound and graphics to take the load off of the 6502 CPU, and it has sprites and collision-detection built into its hardware, so it is an excellent game machine.

They are based on the MOS Technology 6502 CPU running at 1.79 MHz, and were the first home computers designed with custom coprocessor chips. This architecture enabled graphics and sound capabilities more advanced than contemporary machines, …

Nov 5, 2009 · Upon seeing Apple’s success in the early personal computer market, Atari executives ordered their engineers to turn the new hardware into a personal computer system, which became the 800....

Apr 22, 2011 · For 15 years (1978 to 1993), Atari designed and produced four distinct lines of PCs: the 8-bit “Atari 800” line, the 16-bit ST line, the PC compatibles, and the 32-bit series.

Feb 13, 2015 · Both systems use a 1.79 MHz 6502 CPU, along with various co-processors (a rather novel feature for a home computer) that share various computing tasks such as graphics, sprite collision, and sound. The 400 has a 61 key membrane keyboard. The 800 has a standard style 61 key full stroke keyboard.

Despite its label, the XEGS is a true 8-bit Atari computer system. It offers the convenience of a detachable keyboard and built-in Missile Command game, while offering 64K RAM and full compatibility with the 65XE.

The 800 was a full blown 8 bit computer based on the MOS Technology 6502A processor running at 1.70 MHz with up to 48K of user RAM installed. It had a standard QWERTY keyboard with 62 full-travel keys and 4 special keys to the right of the keyboard.

Apr 17, 2003 · See below for specifications and information on this system. Atari daisy-chain cable bus, connects floppy drives, cassette drive, and Atari 850 I/O interface, which includes serial and parallel ports. The Atari 800 was launched simultaneously with its little brother, the Atari 400.

The Atari 8-bit computers are a line of computers that debuted in November 1979 and were discontinued in January 1992. Atari 8-bit computers use the MOS Technology 6502 and, later, the custom Atari "SALLY" variant of the 6502. The Atari 800, along with the reduced-spec Atari 400, were Atari's first two computer systems.
