Variant of a Model F Terminal Keyboard

The so-called "blue switchless" Model F terminal keyboard was a variant of the "blue switch" Model F terminal keyboard specifically for the IBM 3101 ASCII Display Station, lacking the blue switch feature found on its cousins. The internal assembly is largely interchangeable with its cousin, but the layout is more PC-like with the inclusion of a numeric keypad in place of the largest (right-most) function bank.
