IBM Model M SSK
The IBM Space Saving Keyboard (SSK) was an optional peripheral for the PS/2 personal computer. Although originally not as popular as the full-size Model M which included a number pad key cluster, the SSK has developed a loyal following among vintage keyboard collectors and enthusiasts. Due to the popularity of the full-size Model M, there are now relatively few SSKs to be found for sale or scrap. Those that do turn up quickly sell for top dollar, even in very poor condition.
This particular SSK, dated December 14, 1987, was rescued from an e-cycler, then fully cleaned and restored. The keycaps (many of which were broken or missing) have been replaced with a replica set produced by Unicomp, Inc.
