The Atari Stacy was launched in 1989.  Atari had been talking about  a portable ST since 1986, but it was fast tracked for launch when the ST became increasingly more popular with musicians, and feedback was such that it was a viable product to launch for this niche market alone.

In late 1988, the first mock-up  units (made from foam) were shown to industry insiders and privileged journalists, the response was very positive.  A truly global project, design work was carried out in the Sunnyvale HQ, Cambridge UK, and with final board layouts produced by Atari in Japan, which is where the fist units were manufactured.

Released with 2 and 4MB versions with a 20 and 40MB hard drive, the unit retailed initially at over $2,299.00, which was still cheaper than Apple's first portable at just under $5,000.00!  The Stacy used a backlit LCD display, running the ST high monochrome resolution.  It came with all the specifications of a standard desktop 1040ST in a luggable, but still transportable package!

The Stacy would be manufactured from 1989 until 1991, when the ST Book was planned as its lightweight, battery saving alternative.
