I'll donate for one board and might have you assemble it for me.
I already have too many projects that are not being worked on at the moment and I don't know when I will be able to start working on them.
I think your next project should be a MiniMig3.0 that is a reduced size version, say about 3-1/2" square to fit inside the base of a joystick. Even if it had to be two boards sandwiched together to get it that small, it would be very marketable at that form factor. Or probably better yet, get it reduced enough to fit into a PSP sized form including the LCD screen and a rechargeable battery to power it.
I know that UAE already exists for the PSP, but I don't think it runs Amiga games as well as the MiniMig.
