Introduction
4BSD (November 1980) offered a number of enhancements over 3BSD, notably job control in the previously released csh, delivermail (the antecedent of sendmail), "reliable" signals, and the Curses programming library. In a 1985 review of BSD releases, John Quarterman et al., wrote:
4BSD was the operating system of choice for VAXs from the beginning until the release of System III (1979–1982) [...] Most organizations would buy a 32V license and order 4BSD from Berkeley without ever bothering to get a 32V tape. Many installations inside the Bell System ran 4.1BSD (many still do, and many others run 4.2BSD).4.1BSD (June 1981) was a response to criticisms of BSD's performance relative to the dominant VAX operating system, VMS. The 4.1BSD kernel was systematically tuned up by Bill Joy until it could perform as well as VMS on several benchmarks. The release would have been called 5BSD, but after objections from AT&T the name was changed; AT&T feared confusion with AT&T's UNIX System V.

- Install cygwin
- install bzip2 (or 7z) and uudecode
- Install SimH 4.1 from here. This is another fork project from the original emulator.
