More about this type of keyboard...
The Functional Key Keyboard Type II was a slight revision over the previous version made only months after the Type I's introduction. Whilst the general appearance remained the same, the dual-setting feet were lost in favour of an elongated version of the standard Enhanced Keyboard feet and DIP switches became an optional feature. The 24-key function key block was still labelled either "Cmdxx" or "PFxx". These are also commonly referred to as the "M122" like the other Model M Functional Key Keyboards, and thus "Type II" is used to help distinguish it from the others (in particular, from its very similar predecessor).
