SNKB-M1993-EIN-101

Notes

This was originally a beige keyboard, however, I received the keyboard with a damaged case and thus took the opportunity to place the working assembly inside a new-old-stock 1995 industry grey case (P/N 1394942) sold by Unicomp. I also fitted several blue keycaps vaguely echoing the format of Mopar industrial SSKs.

About this keyboard type

The Enhanced Keyboard was the first home consumer, most common and the definitive Model M keyboard, becoming IBM's choice keyboard for a decade after its release and still in production today as the Unicomp Classic. Labelled as being "enhanced" in regards to its layout that became an industry standard and still used today with the addition of GUI keys, the Model M is perhaps the most well-known keyboard of all time thanks to the success of the Enhanced Keyboard and its main host system - the IBM Personal System/2 series. The Enhanced Keyboard was also made available for IBM's earlier "classic" Personal Computer series in both XT and AT flavours, and several other distinct variants exist for other types of systems and custom orders from third-party companies such Dell, Sabre and General Electric.
