iv'e got several USB keyboards but my IBM ps2 is far superior build wise
i would like to convert it if possible
can we let this thread run a while to see if anyone might have done this
thanks
 
back in the day, yes, lots of times, as we all transitioned from PS/2 to USB devices.
was the adapter you tried one of these type;

and did you reboot the PC after plugging in the keyboard as PS2 ports are only initialised at startup.
from memory, always found those adapters worked for me.
 
i have tried several adapters but none work with my ibm102 keyboard ( plugging then rebooting )
i think these adapters are passive
i have seen it done in the past with a small active adapter circuit
 
See if this helps also read the Warning that is there as well.

 
some ps2 devices require an active ps2->usb connector and do not work correctly with just a wire switchover.
i found a circuit using a microcontroller but its not really presented wih diy in mind
a manufactured version might be an option depending on availabiltity and price
other than that it seems like a lost cause

these adapters dont work with legacy devices
they only work if the device has both usb and ps2 protocol
built in its design . . . they can be useful but not in
this instance
thanks
 
sorry, too deep for me.
I'd simply be getting an equivalent well built mechanical replacement USB keyboard.
let's face it, sentimental value aside, you're going to have to bite the bullet one day.

I gave up when I saw that diagram in post #7 where it had (to my knowledge) the USB pin layout wrong on the left hand side.
below is what I've been using for making USB connections, but maybe that diagram is what's needed to convert to PS/2.
