Been slowly making progress on my 6502 homebrew computer, with things like a keyboard I took out of an old Tandy word processor, reading its keyboard matrix with an ATMega, and sending ASCII to the 6502. Writing an OS for it in assembly, with an 8 bit FAT file system (using serial EEPROMs for storage) has also been a very rewarding learning experience.
