1.2. What is the operating system? Its origins?
The operating system is based on UNIX System V Release 2, with
extensions from BSD 4.1, BSD 4.2, System V Release 3 and Convergent
Technologies. The most recent version is 3.51, with a 3.51m FIXDISK
(2.0) available. The FIXDISK was available from AT&T directly, but is
now only available on the OSU Archives as FIXDISK2.0+IN.
