I built a 6502 breadboard computer years ago. Yours is so much cleaner than mine was. This is another great resource for 6502 homebrew. wilsonminesco.com/6502primer/

Definitely a great resource. I’ve got it bookmarked to read more of later. From the address decoding chapter, I can now better appreciate Ben’s weird memory layout that leaves half of the RAM inaccessible. It allows you to hook up a ton of peripherals and use the individual address lines to select them. You can even select multiple devices to write to simultaneously, depending on which part of the address space you access.
