Build ITS from scratch
About ITS
ITS, the Incompatible Timesharing System, is an operating system for the PDP-10 computer family. It was written by hackers at MIT in the 1960s. The MIT site was shut down in 1990, but enthusiasts continue to operate ITS systems to this day.
Building it from scratch
This repository contains source code, tools, and scripts to build ITS from scratch.
-
First, magnetic tape images are created from files in
srcandbin. There are two bootable tapes, and one tape with files in DSKDMP backup format. -
Then the tapes are used to create a file system on an RP06 disk and populate it with a minimal system, and also source code.
-
Finally, the system is booted from the disk, and MIDAS is invoked to assemble ITS from source code.
