Writing

A 6809 board that recorded MIDI and spoke SDLC

Five of us built one microprocessor board in 1987 and submitted it for two courses at once. It bridged a synthesiser and a VAX, and it was meant to be where Rubato came out.

Projects

lisp-cc

The C compiler I wrote in LISP for Bruce Ellis's Compiler Techniques subject at Sydney, recovered and grown into a full K&R 1978 compiler that emits arm64 instead of VAX. Ships with a reconstruction of the LISP interpreter it was marked against and the 1979 Seventh Edition C library, so the whole thing still bootstraps itself to a byte-identical fixed point.
