More about this type of keyboard...
The so-called "unsaver" is the tenkeyless and original version of IBM's Functional Key Keyboards, made available for the IBM 3290 Information Panel and IBM 5080 Graphics System. It comes with both an XT-style 10-key function bank to the left of the alphanumeric block and a 24-key "PFxx" function key block above the alphanumeric block. The term "unsaver" describes the oxymoronic nature of this being a space-efficient design of an ever-larger keyboard despite the fact these are still as large as full-sized keyboards. These also feature two-setting feet, and their ISO-like layout likely played a role in cementing its usage with the later Model M keyboards.
