After finding that Unix v1 was out there, and that it can run on the PDP-11, I thought that it was an ideal target for taking my IsoCobbler tool for a spin. So this is how I used IsoCobbler to make a bootable CD containing the first version of Unix, circa 1972:
1) Download a copy of SIMH 3.81 for DOS, from this location: http://sourceforge.net/projects/simh/files/simh%20binaries/3-8.1/
2) Inside the "simh-3.8-1_MS-DOSi386-exe.zip" file, find this path: simh/pdp11/unixv1. Extract the 6 files inside to a folder.
3) With the extracted files, rename unixv1.bat to start.bat. This will then be started automatically by the disk image.
4) Now add the files in the folder to a new zip file called content.zip. This zip file will be inflated automatically when your boot disk starts.
5) Get IsoCobbler and move your content.zip file into the same folder as the IsoCobbler binaries.
6) Run CobblerConsole (as an administrator), and enter these commands:
7) You should now see a file called UNIX1.ISO in the folder containing the IsoCobbler binaries.
That's it! You have made a bootable ISO containing First Edition Unix. When you boot from the ISO and you're prompted, login as root. Oh, here's the one I created:
I've just found this: http://code.google.com/p/unix-jun72/
Whoa! The first version of Unix, back from the dead. What is also cool, is that the manuals are available too: http://man.cat-v.org/unix-1st/
I would imagine I will be posting a boot disk soon, so that anybody can run the first Unix.
