4 unusual facts about Source Code Control System


BitKeeper

BitKeeper uses history files that are based on the idea of the delta tables and interleaved deltas from SCCS but the BitKeeper history files are made intentionally incompatible by using a different magic number (0x01 0x48 instead of 0x01 0x68) at the beginning.

Source Code Control System

Apart from fixing some Year 2000 problems in 1999, there is no active development on the various UNIX vendor specific SCCS versions.

However, its file format is still used internally by a few other revision control programs, including BitKeeper and TeamWare.

It was originally developed in SNOBOL at Bell Labs in 1972 by Marc Rochkind for an IBM System/370 computer running OS/360 MVT.
