Sanity's Edge is a preserved voice bulletin board system that ran from 1994 to March 1997 in Tampa, Florida. Instead of a modem and screen, callers dialed a phone line (813-989-1950) and navigated spoken menus and prompts played from a single-line PC running the BigMouth/Talking Technology telephony card. The board used an asylum theme with nine message bases (rooms) where users left voice messages; over its lifetime it answered 26,188 calls and recorded 46,610 messages. The preservation includes a faithful 1994 “museum edition,” a 2026 remake with interactive trivia, scans of the original flyer and hand-drawn menu map, and an audio archive of 2,254 decoded files totaling about 24 hours of preserved audio.
The system began as a father-and-son project: a radio-automation programmer father served as sysop (Dr. Null) and wrote the backend while his ten-year-old son Max (user _Xela_) designed menus, the asylum concept, and outreach. A surviving CD backup contained the proprietary audio and program artifacts; a multi-stage reverse-engineering effort using successive AI tools and the REA project decoded the audio codec, recovered recordings, and reconstructed missing C source from machine code. The 2026 digital preservation by Max Rathbone makes the original voice experience available again and documents the technical and human story behind it.
