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. If we can get the simulator working, we may be able to run Sketchpad once again.
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.
