This is a bunch of misc. projects I've randomly done. m6502 is probably the most interesting subdir, it's a small logic-based 6502 emulator that could be used to emulate an Apple I in a small (possibly even AVR) microcontroller. (and it, among many others, could certainly run on a Pi Pico/STM32/RISC-V) ancientARMs is a subproject which I may or may not break out someday with usage notes for old ARM kit. (First up is a NFS boot directory that gets a GUI mostly working on an obscure Pace STB)
