This is a 122-key IBM 3180 terminal keyboard.
I obtained this keyboard in March of 2012 as part of a trade.
Nicknamed “super carrier” by another Geekhack member, in the context of 101-key IBM boards commonly being called “battleships” and new-style 122-key boards being “aircraft carriers”, as the old-style 122 has a larger case.
