It was also the first home computer with integral MIDI support.CoolROM.coms Mac emulator information and download page for Stella (Atari 2600). It had an innovative single-chip graphics subsystem (designed by Shiraz Shivji) which shared the full amount of system memory, in alternating clock cycles, with the processor, similar to the earlier BBC Micro and the Unified Memory systems that have become common today. The Atari ST was the first computer with a fully bit-mapped color GUI. Although the Macintosh was the first widely available computer with a graphical user interface (GUI), it was limited to a monochromatic display on a smaller built-in monitor.

Atari prepared several high-end computers for introduction in 1984, but these were cancelled when the Tramiels took over Atari. The design was a combination of custom chips and commonly available parts in a highly integrated single-board design, fully equipped with standard and custom ports.Prior to the introduction of the ST, Atari's computer division developed and sold a line of home computers based on the 6502 CPU with a set of custom VLSI processors - ANTIC (DMA), CTIA/GTIA (Graphics), POKEY (AUDIO) and PIA (I/O)from 1979 through 1982 as the Atari 400 (16K) and Atari 800 (48k), in 1982 Atari introduced the 1200XL which was too closed a design and was replaced with the 600XL/800XL series. In retrospect this proved to be fortunate as a prototype built on the NS32032 benchmarked slower than the 16/32-bit 68000.The project, codenamed "RBP" for 'Rock Bottom Price', began to form between April and July 1984 into a design that was almost identical to the ST that eventually shipped. Clean my mac for os sierraInterested in Atari's overseas manufacturing and world wide distribution network for his new computer, he approached Atari and entered talks. Atari had plans for a 68000 based machine, code named "Mickey", that would have used custom chips, but details are sparse.The following year, Tramiel discovered that Warner Communications wanted to sell Atari, which at that point was losing about $10,000 a day. In return Atari was to get one-year exclusive use of the design. The company which was later renamed Amiga started selling various video game controllers and games while it developed its "Lorraine" computer system.During development, Amiga had run out of capital to complete the development of its Lorraine chipset, and the "Warner owned" Atari had paid Amiga to continue development work. Run mac osx on an emulatorThe Amiga crew, having continuing serious financial problems, had sought more monetary support from investors that Spring (one of which had been Tramiel and his TTL, which ended quickly given his desire to replace nearly everyone at Amiga). It was during this time in late July/early August that Tramiel representatives discovered the original Amiga contract.It turned out that Amiga was supposed to deliver the Amiga chipset to Atari on June 30, 1984. Was to fire most of Atari's remaining staff and cancel almost all ongoing projects in order to review their continued viability. This was intented to in effect, bar Tramiel from releasing his new computer.One of Tramiel's first acts after forming Atari Corp. After the announcement, Commodore followed by filing lawsuits against four former engineers for theft of trade secrets. Seeing a chance to gain some leverage Tramiel immediately used the situation to countersue Commodore through its new (pending) subsidiary, Amiga, which was done on August 13, 1984. So instead of Amiga delivering the chipset, Commodore delivered a check of $500,000 to Atari on Amiga's behalf, in effect returning the funds invested into Amiga for completion of the Lorraine chipset. The discussions ultimately led to Commodore wanting to purchase Amiga outright, which would (from Commodore's viewpoint) cancel any outstanding contracts - including Atari Inc.'s. Another possibility was Digital Research, who were working on a new GUI-based system then known as Crystal, soon to become GEM. Soon after the buyout Microsoft approached Tramiel with the suggestion that they port Windows to the platform, but the delivery date was out by about two years, far too long for their needs. This delay bought Atari several additional months in 1985 to release Atari STs to Atari User Groups in June 1985 and to go into full retail sales of the Atari 520ST in September 1985.So far as the Atari vs Amiga lawsuit - in March 1987 the two companies had settled out of court in a closed decision.This chapter is used on Wikipedia with permission from The operating system With the hardware design nearing completion, the team started looking at solutions for the operating system. Finally in the fall of 1984 Commodore informed the team that the Lorraine project was active again, the chipset to be improved, the OS developed and the hardware design completed. No word on the status of the chipset, the Lorraine computer system or the team's fate was known. The suit tried to render Commodore's new acquisition (and the source for its next generation of computers) useless and do to Commodore what they were trying to do to him.Meanwhile at Commodore, the Amiga team (according to conversations by Curt Vendel of Atarimuseum.com directly with Dave Needles of Amiga and also with Joe Decuir of Amiga) was sitting in limbo for nearly the entire summer because of the lawsuit.
