Selected Multics Source Programs
(1999) Here is a small selection of nine Multics PL/I and ALM source files, rescued from a mangled copy of the system source formerly hosted at MIT in 1985, corresponding to MR11. These modules are presented for nostalgia and study, and should not be incorporated into any contemporary operating system without the advice of a trained professional.
