Nowadays, the Atari brand belongs to Ex-Infogrames.
Used to build 8 and 64 bits consoles (Atari 2600/5200/7800, Atari Lynx, Atari Jaguar), 8 bits computers, the famous Atari ST (16 bit) and less famous Atari Falcon (32 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, 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 Port : this spawned a generation 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 GUI : easier, really.
- Same Sound Chip : almost.
- Quite powerfull to calculate sweet Data Compression (used in Xyphoes Fantasy)
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 8-bit PCM sound using DMA, with variable rate (50, 25, 12.5 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
