The STacy was released shortly after the Mega ST and was Atari's first attempt at creating a portable ST. The STacy shipped with TOS 1.04 and it's hardware very closely followed the ST upon which it was based.
- All in one design incorporating CPU, keyboard and case
- Built-in monochrome LCD screen, meaning ST high resolution was available only
- Integrated track-ball
- Optional internal SCSI hard drive
The STacy shipped in 3 models:
- STacy = 1 MB RAM, 3.5-inch internal floppy.
- STacy 2 = 2 MB RAM, 3.5-inch internal floppy, 40MB SCSI HD.
- STacy 4 = 4 MB RAM, 3.5-inch internal floppy, 40MB SCSI HD.
An extra floppy drive could be installed instead of the internal hard drive.
While the STacy was a competent ST, it was not successful commercially. The STacy suffered mainly from a short battery life and a fairly heavy weight of 15lbs/7kgs. These issues were addressed in its successor, the ST Book
