2.9 BSD

Logging into a 2.9BSD system
Type: Multitasking, multiuser
Creator: CSRG
Architecture: PDP-11, theoretically portable
This Version: 2.9 (1983)
Date Released: 1983


2.9 BSD is a full UNIX distribution from CSRG. It is an indirect software port of 4.1 BSD; the kernel uses a complicated series of overlays to fit on a PDP-11. Unlike prior versions from BSD for the PDP-11, it does not rely on a prior V6 or V7 system installation.

How do I get this to run?!

Installation is quite slow on SIMH but there is a guide, Installing 2.9 BSD on SIMH. I'll have install tapes, and a pre-made image later.
