As a bit of information me and a friend, if you have not already heard/read, build GCN keyboard adapters and list them on ebay for $29.99.
If you are looking for another solution then please check out:

I am not attepting to advertise and create spam on the site, but would like to point out another solution to people having trouble with Datel.
These adapters are also in U.S. keyboard layout. This means that all they keys type exactly what they say they should. This adapter is compatible with any PS/2 keyboard. I am using a wireless Logitech keyboard with mine here at home. It is nice.
We currently have parts on order, but expect them to be here before the week is over. We should have more listed on there before the week is done.
If you have any questions then you may PM me or contact us through our web site.
