Hi all,
I have an old Logitech keyboard I would like to use that was part of a joblot I bought. Unfortunately the PS/2 connector was damaged and the keyboard did not work. I have a cable to use from a tatty HP KB-0316 keyboard, but just to make things difficult the wiring colours are different, as follows:
Logitech keyboard has green, red, white and yellow + a ground.
HP keyboard has yellow, red, brown and grey + a ground.
Unfortunately having searched google numerous times I've not turned up much. I found a wiring diagram for a Dell keyboard, which had the same colours as the Logitech (I'm sure quite alot of Dell keyboards and mice were actually made by Logitech). Red is +5v, white is ground, yellow is +data and green is +clk.
I used a multimeter on the donor cable from the HP and found that the yellow appeared to be +clk, grey is ground, red is +data and brown is +5v. However I'm not sure this is correct and the best I've had so far is the caps lock light on and that's it!
I've swapped a couple of wires, but I don't want to damage the PCB and components. Does anybody have any ideas what should be matched to what, as I may just call it a day on this one. Of course I could convert to USB, but I wanted to keep it old skool!
Thanks
