Ancient Unix
Some hints from the TUHS mailing list Because browsers are weird, here is some of the keycommands... DEL is the interrupt key (^C on modern *nix), Pause the quit key (^\ or ^L) and PrtScr is EOF (^D).

A silly code example (some Scheme I needed at the time I wrote this into another wiki).
(call-with-input-file "code.txt"
(lambda (port)
(do ((i 0 (+ i 1))
(c (read port) (read port)))
((>= i *code-length*))
(display (list i c))
(newline) )))
Note that the leading spaces automatically produce a display in typewriter font.
HMPQS
The Hypercube Multiple Polynomial Quadratic Sieve (HMPQS) is an algorithm for the factorisation of large (up to about 110 digits, where the Number Field Sieve (NFS) algorithms become more efficient) integers. Uli Meyer has written an implementation in Common Lisp.
