Lines: 13 Off the top of my head, which is probably wrong, PWB UNIX (Programmers Workbench) saw the light of day (out side of ATT) around 1978 and was developed by the group that eventually evolved into the people who were responsible for PWBII, System 3, and System V. It's main raison d'etre was the enhanced ability to keep track of programs to be down loaded to other computer environments (like IBM RJE). SCCS has it's roots here. Originally it was a slightly bug fixed V6 kernel with a couple of enhancements (like the empty() system call) and featured a few extra niceties like the PWB shell, which was distinguished from the existing shell by having things like shell variables and a user setable path. -Ron
