Where did I say anything about doing that?  I hav never touched an
FPGA before and a probably the last operson in this group likely to
have the skills and knowledge to do anythingother than play with it.

I'll be happy if I can just get NitrOS9 running on it.

Although, if people think Gary wouldn;t object, I might demo it for
the students in the Physics Course who are going to be working with
FPGA's later this semester.  I might have to take a COCO in with me
so they can see what it is actually emulating.  If they are like me
they will deinitely be impressed.
