Colossal Cave Adventure in Python... in the browser!
summary
Claims a Python interpreter runs the original FORTRAN IV as-is (PDP-10 quirks: 36‑bit words, five‑letter packed ASCII) and shows it executing via Batavia (Python bytecode in JavaScript) in the browser and via a Twilio SMS webhook backed by Flask. Demonstrates the hacks used, parsing and numeric‑if behavior, performance limits, thousands of SMS plays/month, and that it technically works though the JS VM version is slow and required pragmatic shortcuts.
