SectorLISP is a 512-byte LISP implementation that fits in a boot sector and boots John McCarthy's meta-circular evaluator on bare metal from BIOS. It also includes a readable portable C reference implementation of the same LISP interpreter with a readline-like REPL.

Use cases

  • boot a LISP interpreter from a floppy disk on bare metal
  • study the smallest possible LISP implementation
  • run John McCarthy's meta-circular evaluator
  • learn how LISP can be bootstrapped from scratch
  • experiment with a tiny REPL in a QEMU or emulator environment

When to choose

  • you want the tiniest true LISP implementation for educational or recreational purposes
  • you're interested in bootstrapping programming languages from bare metal
  • you want a readable C reference for a minimal LISP interpreter

When to avoid

  • you need a practical, full-featured LISP or Scheme for real applications
  • you need performance, garbage collection, or standard library support
  • you want a maintained general-purpose interpreter for production use
