  • DIY Old Keyboard 5-pin DIN to PS2 converter

    Sorry, I seemed to have vanished from Instructables for so many years and I have seen many messages in inbox. A lot of people seem to be confused regarding the how to determine the function of the pins. Please refer to Step 4. The function of each pin is fixed but the colours would vary so the main logic is finding which colour wire corresponds to which pin (so you dont need to find the function of each). I did a continuity test or a beep test with the multimeter. Dont worry if you dont have a multimeter. Just take a small led/bulb and a 3V battery with wires. That will work too. Do the same with the PS/2 connector and join the wires and it would work as a PS2 keyboard. PS/2 to USB connections are very cheaply available for a £1 or so your old keyboard can be an emergency backup ...see more »Sorry, I seemed to have vanished from Instructables for so many years and I have seen many messages in inbox.

Also as I mentioned it was kind of a late night idea so I just joined up the wires and not soldered them so it looks a bit rough. I know :) Hope this helps.

    Apologies for late reply. As a PS/2 Keyboard. I am glad you like it :)
