Oldest binary? (Score 1)

I don't know if the code in the application I work on is the OLDEST ... but some of it was last modified in 1993 and has never been recompiled since. Still runs perfectly. Started on a 48bit CISC system and now runs on a 64bit RISC system.

The application runs on a IBM i (formerly System i, formerly iSeries, formerly AS/400).
