it would be remiss to not mention the most excellent ben-eater's 8bit-computer https://eater.net/8bit and ofcourse the nand-to-tetris book + resources (https://www.nand2tetris.org/)

But why is this always the first comment on custom CPU builds? Can't there also be other designs out there?
signa11•17m ago
i look forward to other resources as accessible to those pointed out. by all means, go for it.
