I've moved this over to COFF as it's only tangentially related to Unix.
As a undergraduate I found Doug Comer's Xinu book in the library. At the
time, I was learning C but I only had an Apple ][+ clone which didn't
have a C compiler.
Therefore (obviously), I hand-recoded Xinu in assembly, built a 555
timer circuit, connected it to the IRQ line on the 6502 and got Xinu
up and running (with a shell, with my own ls, with redirection etc.)
on my Apple ][+ clone:
ftp://minnie.tuhs.org/pub/apple2/apple2xinu.tar.gz
Yes, crazy I know.
Cheers, Warren
