Youtuber Rumbledethumps demonstrates the latest iteration of their 6502-based computer. With board manufacturing by PCBWay, only 8 components need to be plugged in without soldering: a 6502, a 6522, a RAM chip, 3 glue logic chips and two Raspberry Pi Pico boards which provide video and USB capabilities, which is uncommon for homebrew computers with such a low parts count.
Clever programming of the Raspberry Pi Pico boards in C provide VGA video, audio and USB connectivity for a keyboard, mouse, and other devices like storage.
See the video below and more on the documentation page and GitHub repo.
