Atari STacy

The STacy is a portable computer version of the Atari ST.

The computer was originally designed to operate on 12 standard C cell flashlight batteries for portability. When Atari realized how quickly the machine would use up a set of batteries (especially when rechargeable batteries of the time supplied insufficient power compared to the intended alkalines), they simply glued the lid of the battery compartment shut.

The STacy has features similar to the Macintosh Portable, a version of Apple's Macintosh computer which contained a built in keyboard and monitor.

With built-in MIDI, the STacy enjoyed success for running music-sequencer software and as a controller of musical instruments among both amateurs and well-known musicians.

History
The Stacy was a global project, design work was carried out in the Sunnyvale HQ, Cambridge UK, final PCB layouts were produced by Atari in Japan, which is where the first units were manufactured, with final manufacturing occurring in Taiwan.

The distinctive sculptured charcoal-gray case was designed by Ira Velinsky, Atari's chief Industrial Designer.
