Well the source code for the minimig port is open source and they have a lot of docs on the website to allow third parties
to write for the c-one board. Yes the c-one is bigger but it has a lot more IO.
You can look at the source code on the download page just put up tonight.

The C-one is larger but it fits pretty well in a standard ATX case and Power Supply.

C-One isn't open source and, I suspect, neither will Clone-A be.
And the C-One is also bigger than the Minimig.
