To mark the 40th anniversary of the prototype demonstration in Kildall´s backyard tool shed in Pacific Grove in the fall of 1974, the Computer History Museum is pleased to make available, for non-commercial use, the source code of several of the early releases of CP/M.
We are releasing scanned printer listings and/or machine-readable source code for four early versions of CP/M dating from 1975 to 1979. Some versions are incomplete, but please don’t ask us for what is missing because we are releasing everything we have.
