[Coco] CoCo 3 FPGA?

[Leonard]

I smell a development board in my future!  Even if it only does 12Mhz,
that's still a lot faster then we now have.  I hate to bring this up, but
does this have the markings of a coco4?  Guess if you're a purist it
doesn't, but it seems like good fun anyway:)!

Remember, I just pulled that number out of thin air, though I don't
think it's wildly unrealistic that an FPGA CoCo could someday run that
fast.  According to Gary's web site, he has it running at 6.25 MHz
which, while far from 50, is still a heck of a lot faster than any
"real" CoCo 3.
