3BSD

3 BSD/VM
Logging into a 3 BSD/VM system
Type:	Multitasking, multiuser
Creator:	CSRG
Architecture:	VAX, theoretically portable
This Version:	3.0 (1979)
Date Released:	1979

3BSD (called the Third Berkeley Software Distribution in contemporary documentation, generally given as the acronym) was Unix/32V with a better virtual memory system, that went from 32V's swapping, to a paged system. Additionally all of the BSD tools from 1BSD & 2BSD on the PDP-11 were ported over, including vi. I've poorly transcribed the setup documentation here Setting up the Third Berkeley Software Tape. This was the first full fledged OS from Berkley, as the 1&2 releases were just patches to V7.

How do I get this to run?!

Right now, make sure you have the VAX-11/780 emulator from SIMH 3.8-0 or higher, then you can follow Installing 3 BSD on SIMH. Alternativly you can go to http://zazie.tom-yam.or.jp/starunix/ for more information.

What Runs?

Not very much.... 3 BSD does not provide any modern networking, and the C compiler is far from ANSI. The DZ11 emulation in SIMH is not working.
