Of course. But I meant the source for which he could "win prizes for minimal or beautiful code". AFAIK none of it is legally available to anyone.

I don't know whether it's legal, but http://www.interact-sw.co.uk/altair/index2.html has an annotated disassembly of Altair BASIC. I haven't given it more than the briefest glance myself, but allegedly there's some very nice stuff there. (Of course it's from a different era and no one outside deeply-embedded-land writes that sort of code any more other than for a twisted kind of fun.)
