I've connected it via an adapter based on Stephen Marsden's IBMKEY design.
It's connected to my A600 for testing purposes - I didn't want to risk it on my A1200 until I was confident it wouldn't do anything nasty.
My main reason for wanting to connect a pc keyboard is that I intend to towerise my A1200. It's far easier (and cheaper) to make a ps2 adapter and connect a pc keyboard than source/buy anything Amiga. IMO modern pc keyboards (made by Logitech, Microsoft, etc.) have greater quality, reliability and style than any Amiga.
I've also made a ps2 adapter for the mouse port. Again, modern optical ps2/usb mice are much more accurate, responsive and reliable than any Amiga mouse.
