Hi all,
I just purchased an XT/AT keyboard that can be switched between protocols via a small switch on the underside. However the switch has a third setting, which I have never seen before. Does anyone know what it's for? The three positions are labelled 88, 286 and 30. 88 is of course XT, and 286 is AT, but what is "30"?
Surely it can't mean PS/2 model 30 because that should be the same protocol as the AT.
