Used to build arcade systems, 8 and 64 bits consoles (Atari 2600/5200/7800, Atari Lynx, Atari Jaguar), [[Atari 8 bits -bit|8-bit computers]], the famous [[Atari ST ]] (16 -bit) and less famous Atari Falcon (32 -bit) == 8 bit == [https://en.wikipedia.org/wiki/Atari_8-bit_family And Atari 8-bit family on the other WIKI] == 16 bit == The [[Atari ST]] was released in 1985, originally with an external PSU and external floppy drive. In 1986, the Atari STF integrated these components inside the machine itself. A version intended for business users was also created in 1987 and named the Mega ST. It featured more RAM, produced a real time clock, a blitter chip for faster rendering and a detached keyboard. These machines were famous for being: *Inferior to the [[Amiga]] yet still better (the war still rages on nowadays). It was easier to do work on Atari, while on Amiga a guru meditation (machine crash) was never far away. Also the TOS was in ROM which mean it could be used immediately and it didn't consume valuable RAM. And as the OS was immutable, less time was spent customizing it and more time was used to do productive work. *A hardware [[MIDI|Midi Port]] : this spawned a generation line of Musician Geeks.  *used widely in Amstrad CPC software developments (mostly games ?). Its use in CPC development (Cross Development) had many advantages : *Quite similar Video Resolutions : 320x200x16.*Possibility of a good [[Graphical User Interface|GUI]] : easier, really.*Same Sound Chip : almost.*Quite powerfull to calculate sweet [[Data Compression]] (used in [[Xyphoes Fantasy]]) [https://en.wikipedia.org/wiki/Atari_ST Atari ST on the other WIKI] The Atari STE followed up in 1989 by adding these new features:* 4096 instead of 512 colour palette* Fine Horizontal and Vertical hardware scrolling* Blitter chip, same as in the Mega ST* Stereo 8IBM-bit PCM sound using DMA, with variable rate (50, 25, 12compatible PCs.5 and 6.25KHz)* 256KB ROM instead of 192KB, containing the TOS* Four 30-pin SIMM-slots, for up to 4 MB RAM* Extended and analogue capable joystick ports
