Do you mean a PS/2 connector, or a five pin DIN? Or even one of the earlier connectors; I had an IBM keyboard once that was something I can only imagine predated the 5 pin DIN. PS/2 to five pin DIN (and vice-versa) was easy enough, but I never did get that keyboard connected to anything. I'm typing this on a Model M I picked up from my keyboard corner just now. As I recall, this one doesn't work well; pretty soon, it will stop registering some keypresses. Never have been able to work out why :/
