We are trying to create a simulator for Lincoln Lab's historic TX-2 computer. Notably, this is the computer on which Ivan Sutherland's Sketchpad program ran.
From the Wikipedia entry for the TX-2:
The MIT Lincoln Laboratory TX-2 computer was the successor to the Lincoln TX-0 and was known for its role in advancing both artificial intelligence and human–computer interaction. Wesley A. Clark was the chief architect of the TX-2.
The OVERVIEW file explains the high-level design of the simulator. More information is available at the TX-2 Project's website.
The simulator doesn't emulate all the features of the original TX-2 yet, but you can still try it out.
You can try it on-line here.
To run the web-based version locally yourself, follow these instructions.
Hardware emulation is much less complete in the command-line version.
You can try out the command-line simulator and tools by following these instructions.
If you are considering contributing, first of all, thanks!
We have quite a lot of documentation about the operation and programming of the TX-2. This is what our implementation is based on.
Please see our Contributor's Guide for information on what we need and how you can help. The Guide also explains what non-coding contributions are needed and how to identify a good "first issue" to pick up.
