The term “Crayette” was coined by the tech magazine Datamation to describe a wave of 1980s and 1990s startup companies that built minisupercomputers. These systems aimed to deliver a fraction of a true Cray supercomputer’s power—usually using lower-cost, air-cooled CMOS components—at a drastically reduced price point, often maintaining software compatibility with Cray’s instruction set.

John Schmuhl reports on FB: I had the honor of managing the Cray-2 supercomputer site at the US Army Tank Automotive Research, Development and Engineering Center in Warren, Michigan. Ours was Serial Number SN2014. The Cray-2 4 cpu 256 GBytes DRAM was installed in the summer and fall of 1987, went online in January 1988,
The series of Cray systems that went to Sweden started with Cray-1 SN9 later to be replaced by XMP SN206 and others. Unusually the system was shared between The University at Linkoping and Saab-Scania using the Multi Level Security features of Unicos. Work on Jets, cars and trucks was completed. from Auto Week in 1987
