This video shows the MegaWang with a new user port board design that is planned to add several gigabytes of external memory to the Commodore 64, as well as providing fast DMA to the MegaWang hardware. This expansion board would allow fast screen scrolling, FMV, etc.
This is part of a modular audio and video hardware for retro machines like the Commodore 64. Designed to use 74LS series TTL ICs available back in the 1980s/1990s, something you can solder at home from parts or order ready assembled.
