No doubt capable, but way too big to hide in a cc3 unless the whole coco 
was emulated.

That maybe could be hidden under the keyboard.  With a vga output no less.

Would I have to run the development system on windows?  If yes, no deal.

For about 90 bucks and some time, that looks like a usable gizmo.  IIRC, 
the development stuff for xilinx is nearly free, so that, and custom made 
breakout cables might add a lot of functionality to a coco3.

Thanks John.
