Here are my goals and rules. I always set out strict rules to make the challenge more difficult.

**** GOALS ****
1) The VIC-20 cannot be altered on the inside in any way. It must remain pristine.
2) Video must be VGA with a minimum of 400x600 or 640x480 resolution.
3) Color palette must be at least 4096 colors on the screen simultaneously.
4) The VIC will be able to access 16 Megabytes of super fast Audio / Video memory.
5) A blitter system will be capable of drawing sprites if any size at 8MHZ minimum bandwidth.
6) Sound will be at least 4 channels of 8 bit sampled sound.

**** RULES ****
1) Only VIC-20 era logic components and static memory may be used.
2) All chips must be DIP format, and all testing will be done on a breadboard.
3) All chips must still be available and produced by more than one company today.
4) No special ICs such as FPGAs, GALs, or even ROMs will be used. Just pure 74 logic.

Yyyy.... Najlepsze podsumowanie https://youtu.be/djIPFMWGk-8?t=5987
