The code from the main project I worked on out in Marlboro (for Digital Equipment Corporation Large Computer Software Engineering) is up on the web!
This proves that I really have been using source control systems since the 1980s (I think this was DEC CMS), and that I wrote BLISS code, and that I wrote many metric fuck-tons of comments.
Possibly the weirdest bit is this floating-point number conversion code. It handles pdp-11/vax 32 and 64 bit floating point, and PDP-10 36 and 72 bit floating point, and can convert anything to anything (within format limitations). It’s at http://pdp-10.trailing-edge.com/bb-r775d-bm_tops20_ks_upd_4/01/sources/dixfp.bli.html
Although the declaration of the character tables for various character sets might be a runner-up. (Bliss had far and away the most powerful macro facilities of any language I’ve ever used.)
