The Tramiels were now leading the world to the first 16 bit computer. They had introduced the 130ST and the 520ST At the Winter CES show in 1985. These computers were to combat the Macintosh in power and in price and did quite well taking charge of the Computer races. It was a very cheap computer for being such a well built computer. The original 520ST was not able to get the finished version of GEM AND TOS into the 194kb ROM so a disk had to be also sold with it to load the GUI into RAM, this left only about 320kb of RAM left and made many Atari customers a little upset with Atari, this had been corrected within the year though and a new larger ROM chip had replaced the old one.
