Even on the AT, the protocol works, but you need a cable adapter.
Maybe.
I have one or two detachable Model-M cables that have a DIN-5
connector instead of a MiniDIN-6. Just don't ask me to try and
find them. :)
I have a few IBM 101-key keyboards that have detachable cords, and
the DIN-5 connector, but they're not Model Ms.
They have completely different part numbers and stiffer key feel.
They also have older square IBM logos.
But, the cables fit and work with Model M's.
Thus, you don't need a cable adapter. (The keyboards and cables store
better when the cable is detached from the keyboard anyhow.)
