The release of the first Atari 520ST followed months of work after Atari was bought by Jack Tramiel. The company had been losing money with its consumer products, including video game consoles. In the first year, the Atari ST sold many thousands of units, and in the estimations of many, saved the company.
The Atari 520ST and subsequent 1040ST model pioneered a color GUI and offered internal MIDI ports for music software. Popular software for the Atari ST also included early desktop publishing and database programs.
The development of the Atari ST led to other STF and STFM models, including a model called “Stacy” that shipped with a trackball in the keyboard. Various peripherals including fax machines and printers were also available. These computers also utilized floppy disk drives; in fact, in the initial release, some computers had to be shipped with the operating system on floppy disk, until it was built into ROMs.
