Atari Computers

Welcome to my Atari collection.

This page is a repository for all of the Atari systems, peripherals, and accessories in my collection – it’s currently a work-in-progress, and I’ll continue to add things as and when I have the time.

The Atari 2600 is a home video game console developed and produced by Atari, Inc. It popularized the use of microprocessor-based hardware and of games stored on swappable ROM cartridges, a format first used with the Fairchild Channel F in 1976. The VCS was bundled with two joystick controllers, a pair of paddle controllers, and a game cartridge – initially Combat, and later Pac-Man.

The Atari 800XL (1983) was the third version of the Atari 8-bit line of computers, and was introduced in 1983 to replace the Atari 800. The system featured 64KB RAM and all the standard Atari VLSI chips (Antic, GTIA, Pokey, PIA etc) in a smaller and more compact cost-reduced design. The system also included built-in Atari BASIC programming language, and Atari’s new high speed Parallel Bus Interface (PBI).

CPUMotorola 68000 @ 8 MHz
Memory512 KB (4 MB max.)

The Atari 520ST F was a cut-down version of the 1040ST F, and was intended as a replacement for the earlier 520ST – in comparison, it features an internal power supply and a double-sided floppy drive, as opposed to being external, and the joystick/mouse ports were moved to a niche underneath the keyboard. The later 520ST FM models feature an internal RF modulator, allowing the computer to be used with a television.
