These space-saving keyboards were the tenkeyless and compact versions of the IBM Enhanced Keyboard. The original IBM Space Saving Keyboard (SSK) was only available as a non-standard option for the IBM Personal System/2 series, resulting in a relative rarity as numeric keypads were viewed more favourably during the late '80s and '90s. The keyboard is also occasionally referred to as a Model M Mini. A modernised variant entered production in Q2 2020 as the Unicomp Tenkeyless, now featuring a USB modular cable and lock-lights.
