Atari Stacy 4

The Atari Stacy 4 was the highest-memory production Stacy, pairing 4MB of RAM with an internal floppy drive and a 40MB hard disk. It retained the 640x400 monochrome LCD, integrated trackball, full-size keyboard and ST-compatible interfaces of the other models.

With the maximum practical ST memory and more local storage, the Stacy 4 targeted demanding mobile music, publishing and development users. Its rarity, specialised purpose and substantial original price make it the flagship of Atari’s first portable computer family.

Notable Features

• 4MB of RAM, an internal floppy drive and a 40MB hard disk.
• Maintained desktop ST software and MIDI compatibility in a transportable package.

Historical Significance

• Represented the highest factory specification in the Stacy line.
• Aimed at professional users whose projects needed more memory and storage away from a fixed studio.

Collector’s Notes

• The Stacy 4 is scarce and complete working examples command collector interest.
• Check the internal drive, LCD, power supply and battery area carefully before use.
