Cameron Laird's personal notes on Operating Systems

Operating systems I've used in the last decade: SunOS, OpenVMS (AXP and VAX), Solaris, BSDI, AIX, HP/UX, FreeBSD, ODT (SCO Unix), Ultrix, Digital Unix (formerly OSF/1, ...), System 7+ and other MacOSs, Windows, MS-DOS, OS/2, Pyramid's DC/OSx 79 and 87, ... I used to include more links here, but now I just vector searches through Ronnie Nordvik's index to "Computer and software houses", and the Operating Systems on the Web page.
