I think that this is an awesome project. I've just made a donation. I'll definitely be buying a Mega 65 when it is released. (I'll probably end up buying two!).
I used to be part of the c64 demoscene and to have just one of these advanced retro/nostalgia machines would make my day.
I hope that there will be extensive documentation for the computer.
Thanks for the regular updates and keep up the good work.
