The Atari 520ST was introduced at the Winter CES in January 1985, six months before the Commodore Amiga. However, Atari took some precautions, as the operating system didn't yet exist in ROM and had to be loaded from a floppy disk upon power-up (although, of course, the Amiga did too). The 520ST also didn't have an internal floppy disk drive, but later versions included one. | |||
It included an external 3.5-inch, single-sided 360K floppy disk drive, mouse, and monochrome monitor; it was priced at $799. | |||
Both the Amiga and the 520ST were based on the Motorola 68000 CPU, which had a 16-bit external bus and a 32-bit internal bus; hence, the 520 "ST" stands for "sixteen/thirty-two." The operating system is "TOS" or "Tramiel Operating System." | |||
The 520ST (and Amiga) have a graphical operating system, or GUI, similar to that of the Apple Macintosh, which was released a year earlier. The 520ST used Digital Research's GEM GUI, although it's not as good as that of the Macintosh or Amiga. | |||
One thing that IS very good is the built-in VT52 emulation. The 520ST can act as a dumb terminal, communicating through its serial port with another system. | |||
There was a great rivalry between Amiga and Atari users, each convinced that their computer system was superior, or at least hoped it was. | |||
In addition to the 520ST, Atari released the 1040ST, with a built-in floppy disk drive and 1 MB of RAM (the 520ST has 512 KB). | |||
In 1987, the new and improved Mega ST was launched. | |||

A few years later, in 1989, the ST laptop, the Stacy, appeared. | |||
