On a more serious note: What would you want to do with it?
The I/O seems rather awkward -- a nice, but rather small screen, which neither matches the very limited display of the earliest 6502 computers (KIM-1, AIM-65), nor the larger CRT of the later ones (Apple 1 and 2, Commodore PET...). And no keyboard at all. You could connect a serial terminal, but then you don't need the on-board screen.
If you want to dive into 6502 assembly language programming and the "early days, low level" experience, I would recommend that you start with a real 65(C)02 single-board computer. Many hobby projects are documented online; to name just one example, the author of the AVR emulator which you linked to has started with his own "real" 65C02 computer first:
