Thanks mj,
I have tried a pc ps2 into the adapter (using the ps2 to din) and it works so I guess it is the amiga keyboard.
It would seem so, but there have been reported incompatibilities between the PC-Key and earlier Amiga 2000 keyboards
I known it seems obvious due to the process of elimination but I just wanted to see if anyone knew any other reason. I guess I will have to get this resolved with eBay then.
As said, the PC-Key is (probably) incompatible with earlier Amiga 2000 keyboards. By "earlier" I would think the original ones, with a Philips keyboard controller, which also have the smaller F-keys if I'm not mistaken.
Your keyboard however looks like an ordinary, run of the mill, model, so the PC-key shouldn't have any issues with it.
If you want to independently test the keyboard you can connect the GND and +5V pins to ground and power source respectively, and the clock and data pins to the corresponding ones on the A1200's CIA chip (effectively bypassing the keyboard MPU). If it works, you know the keyboard is OK and it's either a partly defective PC key or a new-found incompatibility.
