The Atari ST is a line of home computers from Atari Corporation and the successor to the Atari 8-bit family. The initial model, the 520ST, saw limited release in April–June 1985 and was widely available in July. The 520ST is the first personal computer to come with a bitmapped color GUI, using a version of Digital Research's GEM released in February 1985. The 1040ST, released in 1986, is the first personal computer to ship with a megabyte of RAM in the base configuration and also the first with a cost-per-kilobyte of less than US$1.

Atari ST character setW
Atari ST character set

The Atari ST character set is the character set of the Atari ST personal computer family including the Atari STE, TT and Falcon. It is based on code page 437, the original character set of the IBM PC, and like that set includes ASCII codes 32–126, extended codes for accented letters (diacritics), and other symbols. It differs from code page 437 in using other dingbats at code points 0–31, in exchanging the box-drawing characters 176–223 for the Hebrew alphabet and other symbols, and exchanging code points 158, 236 and 254–255 with the symbols for sharp S, line integral, cubed and macron.

General Instrument AY-3-8910

The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's Gyruss contains five—and pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge for the TRS-80 Color Computer.

Happy drivesW
Happy drives

Happy drives are series of disk drive enhancements for the Atari 8-bit and Atari ST computer families produced by a small company Happy Computers. Happy Computers is most noted for the add-in boards for the Atari 810 and Atari 1050 disk drives, which achieved a tremendous speed improvement for reading and writing, and for the ability to "back up" floppies. Happy's products were among the most popular Atari computer add-ons. They were still in use and active in the aftermarket as of 2009.

Atari MEGA STEW
Atari MEGA STE

The Atari Mega STE was Atari Corporation's last ST series personal computer, released in 1991. The MEGA STE was essentially a late-model 680x0-based STE mounted in the case of the otherwise unrelated Atari TT computer, although a number of TT features were also blended in. The resulting machine was a more business-like version of the ST line.

ST BOOKW
ST BOOK

The ST BOOK is a portable computer released in 1991 by Atari. It was based on the Atari STE. The ST BOOK was vastly more portable than the previous Atari portable, the STacy, but it sacrificed several features in order to achieve this: notably the backlight, and internal floppy disc drive.

Atari TT030W
Atari TT030

The Atari TT030 is a member of the Atari ST family, released in 1990. It was originally intended to be a high-end Unix workstation, but Atari took two years to release a port of Unix SVR4 for the TT, which prevented the TT from ever being seriously considered in its intended market.
