Turn your PC into a PDP-11 running Seventh Edition UNIX. This way you can run UNIX just like Dennis Ritchie and Ken Thompson did back in 1979. This is a sanos port of Bob Supnik’s PDP-11 simulator. I have made an ISO image with sanos, the PDP-11 simulator, and the UNIX V7 kit from The Computer History Simulation Project. Just put the CD-ROM in your PC and boot. Then your PC is turned into a PDP-11 running UNIX V7! This is great fun if you’re a nostalgic UNIX geek.
If your want to try the UNIX V7 demo first download and unzip the ISO image. You can burn this image to a CD-ROM using your favorite CD-burner program and then boot the computer from the CD-ROM. You can also try it out using VMware by setting pdp11.iso as the ISO image for the CD-ROM device. You can get the source I have used to build the image here.
When you boot from the CD-ROM, sanos boots and starts the PDP-11 simulator. The simulator then boots UNIX V7 from the image.
