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). *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
