I was watching a video on Hackaday with Bil Herd and he made me interested in the PSOC4 board which is basically a programmable system on a chip and it uses Arduino style shields (daughterboards). Then I got the idea that the 6502 could be on a daughterboard for this platform and what power that could bring to your users.
Think about this. With software, you can add digital, analog or other circuits like a UART to your 6502? It is just a $25 dollar board.
