Care was taken to make sure that electrical compatibility was 
maintained.  The new units plug up to the same connector and the only 
difference is software.  This has been verified.

Mechanical wise there are some differences but for spare parts we needed 
be able to put a new kbc+touchpad in to older machines.  Various plastic 
parts also have to swap to allow that to happen.

To date all the retrofits involve a good bit of mechanical hacking.   We 
should have new pre-build machines with the new plastics at 1cc in the 
near future and can see how well it works in practice.  I'm not saying 
it works until I see it but thats what we were striving for.
