Not so classic Compaq keyboard help

Apologies if this is not classic enough :-) Very quick story - I'm a rather eclectic collector and have a range of very nice early Compaq server gear (couple of servers, a KVM and a hub etc) which go back a way and thought it would all look good sitting in a rack. Recently got lucky and picked up a Compaq rack for free. More recently got even luckier and a friend said her work was throwing out some stuff including a keyboard in a tray. I said I'd have it (like any collector, without knowing exactly what it was - better I have it than its find its way into a bin) - turned out to be a Compaq keyboard (158649-001) in a 1U rack mount keyboard tray - bonus. But when they removed it from the rack instead of removing it gracefully they just cut the cable. Grrrrr - how often does that happen when people are "removing" stuff! The keyboard has a single cable coming out of it with a Y piece that's splits into to 2 PS2 plugs. They cut off the Y piece and the plugs so I'm left with a single cable and no ends. Have been scouring the net for quite a while looking for any specific info on this keyboard to see if I can repair it but no joy. Be most grateful if anyone can point me somewhere I may not have covered. Thank you!!! ++++++++++ Kevin Parker ++++++++++
