COMMODORE 64 · COMPANION SPEC

MUD64

Flip-screen adventures, PETSCII, and silicon — authored in plain .mud. Separate from MUD-SPEC (core MarkUpDown). Inspired by Microtext 2.6.

Archivist spark: Perifractic rediscovered Microtext 2.6 · Weasel's World transcribed the manual · Team DC built MUD64. Peri broke the seal. We built the cathedral.
