Atari ST

The Atari ST was the first TOS machine developed by Atari Corporation, being released in 1985. For the time, the ST featured a powerful processor, a large amount of memory, a colourful display, and an easy-to-use GUI operating system, all for a very cheap price. These attributes all contributed to ST representing a significant evolution in the personal computer market, and consequently it was a massive commercial success. Without this success, the TOS Family would not have existed.
