SectorLISP now fits in one sector

In plain words

SectorLISP is a LISP programming language implementation designed to fit within a single disk sector. Launched in 2021, it demonstrates how a functional programming language can be compressed into minimal storage space. The project is for developers and programming enthusiasts interested in compact code implementations and retro computing. What stands out is the technical achievement of creating a fully functional LISP interpreter with extreme size constraints, making it a novel exploration of language design efficiency.

So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…
