History Platform / AtariST

* The [=STe=] models add a DMA-driven stereo PCM sound codec (called a DSP by Atari marketing materials) to provide for improved speech and sound effects.

* MPU-401 compatible MIDI I/O. This allowed the ST to interface with external MIDI devices, making it a staple in many recording studios. Likewise, the Atari ST became the only other computer of western origin that had games (mostly Creator/{{Sierra}} titles) that supported the Roland MT-32 synthesizer.

* 3 channels square waveforms plus one channel for noise. While this was actually technically inferior to the POKEY chip used by Atari's prior 8-bit line, in practice it was a non-issue, as the AY-3-8912 and its derivatives were far more widespread (thus making it easier to port games to the platform), and anyone who really cared about audio could just use the MIDI ports to hook in vastly more capable devices. And anyone who really, truly cared could also use the PSG to play back multichannel PCM tracker music, made possible by the efficiency of the Motorola 68000 CPU.

Jack wanted a new computer, and fast. A lot of his friends from Commodore had left to follow him, so a combination of Atari and ex-Commodore engineers started working frantically to get something ready for the Winter Consumer Electronics Show coming up in January '85. The Motorola 68000 was chosen to be the UsefulNotes/{{C|entralProcessingUnit}}PU. UsefulNotes/{{R|andomAccessMemory}}AM started at 128K, but was 512K by the time the computer was done. A custom UsefulNotes/{{G|raphicsProcessingUnit}}PU called Shifter allowed three screen modes. Sound would be the General Instrument AY-3-8912. The operating system was to be a port of Digital Research's CP/M, but it proved too primitive and was replaced by a new OS that DR was developing, called GEMDOS. A graphical user interface on top of GEMDOS completed the OS, called TOS ("Total Operating System", or "Tramiel Operating System", but usually just "The Operating System"). Since Jack's computer had similar features to the AppleMacintosh but sold at a far lower price, it was nicknamed the "Jackintosh" by the press.
