Unix's first edition has been restored by the work of Warren Toomey, Tim Newsham and others. The current project homepage is located here.

PDP-7

The first version was to have been written in assembly for a spare PDP-7 in Bell Labs. Originally what started out as a game (spacelander) eventually UNIX started to fill a need for typesetting on 'cheap' minicomputers.

The first version was primarly written in assembler.

Restoration project

On December 2008, the project made it's first relase using scanned printouts as source material, a team was able to re-enter the source files, and using apout they were able to construct a system using various bits from later unix versions into a booting system for SIMH's PDP-11 emulator.

How do I get this to run?!

The current binary build can be downloaded from the google code page here.

You need a version of SIMH 3.8-0 or higher, as they will incorporate certain changes required for v1 unix.

What Runs?

Not very much!
