Atari ST Internals has pages packed with information for the user who needs to get work done now. Abacus has covered nearly every aspect of the ST. There are chapters covering all the "off-the-shelf" chips inside the computer. GLUE does just that, replacing many separate ICs with a single package for controlling basic system timing. Abacus has even included a section on how to use the "back-door" into the ST--the Line-A interface--along with sample programs.

Learn how and when to remove this template message Atari initially used single-sided 3. Some commercial software, particularly games, shipped by default on single-sided disks, even supplying two kB floppies instead of a single double-sided one, for fear of alienating early adopters. The Atari ST uses that info, so it can operate with floppies formatted either way. Achieving successful data interchange between the two platforms normally meant using floppies formatted by MSDOS, or by third party formatting utilities that were later released for the Atari ST.
Other utilities allowed for transfer with unusual formats, such as the Commodor Amiga. The machine is generally similar to the earlier ST, but moved the power supply and a double-sided floppy drive into the rear of the housing of the computer, as opposed to being external.
This added to the size of the machine, but reduced cable clutter in the back. The choice of model numbers was inherited from the model numbers of the XE series of the Atari 8-bit family of computers. A limited number of STFs shipped with a single-sided floppy drive. To address this growing market segment, Atari came up with the ST1. Debuted at Comdex in , it was received favorably. Renamed the Mega, this new machine includes a high-quality detached keyboard, a stronger case to support the weight of a monitor, and an internal bus expansion connector.
A 20 MB hard drive called the SH could be purchased as an option and stacked below or above the main case of the Mega. The upcoming SLM laser printer would not come with a processor or memory, reducing costs.
Initially equipped with 2 or 4 MB a 1 MB version, the Mega 1 would later follow , the Mega machines would complement the Atari laser printer for a low-cost desktop publishing package, which received acclaim and was featured on the cover of Computer Shopper magazine. A custom blitter co-processor was to be included to speed the performance of some graphics operations on the screen, but due to delays it was eventually released on the Mega 2 and Mega 4 machines.
Developers wanting to use it had to detect for it in their programs because it was not present on all machines. Two enhanced joystick ports were added two normal joysticks can be plugged into each port with an adapter , with the new connectors placed in more easily accessed locations on the side of the case. Furthermore, even having a joystick plugged in would sometimes cause strange behavior with a few applications such as the WYSIWYG word-processor application 1st Word Plus.
It also shipped with TOS 2. It was marketed as more affordable than a TT but more powerful than an ordinary ST. Originally planned with a CPU, the TT included improved graphics and more powerful support chips.
The case was a new design with an integrated hard-drive enclosure. The final ST computer is the multimedia-capable Atari Falcon Although the microprocessor is capable of using bit memory, the Falcon uses a bit bus which affects performance, but also served to reduce its cost. Aftermarket upgrade kits were available that allowed the Falcon to be put in a desktop or rack-mount case, with the keyboard separate.
Released in , the Falcon was discontinued by Atari the following year. Software[ edit ] As with the Atari 8-bit computers,     software publishers attributed their reluctance to produce Atari ST products in part to—as Compute! He stated that he had been warned by competitors that releasing a game like Falcon on the ST would fail because BBSs would widely disseminate it.
Within 30 days of releasing the non- copy protected ST version, the game was available on BBSs with maps and code wheels. He reported that the Amiga version sold in six weeks twice as much as the ST version in nine weeks, and that the Mac and PC versions had four times the sales. Computer Gaming World stated "This is certainly the clearest exposition Another popular and powerful ST music sequencer application, Dr. An innovative music composition program that combines the sample playing abilities of a tracker with conventional music notation which was usually only found in MIDI software is called Quartet after its four-note polyphonic tracker, which displays one monophonic stave at a time on color screens.
Due to the ST having comparatively large amounts of memory for the time, sound sampling packages became a realistic proposition. The Microdeal Replay Professional product features a sound sampler that cleverly uses the ST cartridge port to read in parallel from the cartridge port from the ADC. MID format. GVox bought out Passport, and continues the program for Windows and macOS along with the other Passport product, the notation program Encore , which is as of marketed and maintained by a new iteration, Passport Music Software, LLC.
This software was created by Gene Mosher under the ViewTouch  copyright and trademark. Software development[ edit ] The initial development kit from Atari included a computer and manuals. Included with the kit were a resource kit, C compiler first Alcyon C, then Mark Williams C , debugger, and assembler plus the non-disclosure agreement. The realtime pseudo-3D role-playing video game Dungeon Master , was developed and released first on the ST, and was the best-selling software ever produced for the platform.
The critically acclaimed Another World was originally released for ST and Amiga in with the engine developed on the ST and the rotoscoped animations created on the Amiga. The first version was built for Atari ST with his collaboration in January PC-Ditto came in two versions: software-only, and a hardware version that plugs into the cartridge slot or kludges internally.
