Unix V8
Eigth edition unix v8.png
(none yet)
Type: Multitasking, multiuser
Creator: Bell Labs
Architecture: VAX
Current Version: v8
Year Introduced: 1985


A version of 8th Edition Unix was recently released by Alcatel-Lucent and is available here for download. It is not a complete distribution tape, just a tar file of a running system, made by Dan Cross.

Actually, "released" is too strong a word. They just signed a letter saying that they won't sue for the release of v8-v10 Unix. The letter can be read here (PDF).

Notable features

Unix v8 includes the stream interface (in /usr/include/sys/stream.h), as opposed to the socket interface, for doing network programming.

Also included are PDP-11 cross-compilers and associated tools (assembler, linker, etc) as /usr/bin/{11cc,11as,...}

Getting it to run on SimH

Here are some instructions. Some things must be done slightly different or in a different order though. For example you either need an old(er) version of SimH to run it, like 3.8, or use "set noasync" in your configs, otherwise you will get I/O errors.

Boot messages of a v8 system running in SimH:
