the virtual data center
a fully working walkable
1401 3D simulation - for free  

This project is based on the work of the IBM 1401 team at the Computer History Museum,
the videos and information of CuriousMarc, and the documents made available via bitsavers.org

The 1401 simulator is intended solely for educational and informational purposes.
We do not guarantee any usefulness or correctness.
It may be distributed and used freely as a whole; add credits and link to this page.
Use in commercial settings allowed (e.g. training / education), but commercial distribution prohibited (e.g. SW collections).
This SW is not public domain. Any disassembly or extractrion of its parts or assets or algorithms is not allowed.
Any third party rights still apply and remain unaffected.

This program is an enthusiast's project and is not related to or promoted by IBM
All assumptions are based on manuals and other people's videos and websites, so take it with a grain of salt.
If you encounter poblems or have suggestions for improvement, feel free to contact me via email or have a look at the discord server.

There's no kind of user data collection implemented directly into the 1401 simulation,
nevertheless we can't speak for the used framework (Unreal Engine and the PlugIns).
Please turn to Epic Games' website if you wish for further information.
However no network connection needed; you may block any traffic e.g. in the OS firewall.
