## How You Can Help

The Computer History Simulation Project is a volunteer effort by enthusiasts world-wide. If you are interested in preserving computing's history, you can help with the project by extending the existing simulators or writing new ones. Additional work needed includes:

- Recovering additional software; see the Items Needed list above.
- Debugging simulators. There are always additional software sets to try or debug... OS2/MT on Interdata, for example.
- Writing additional simulators. Is your favorite system languishing in the dustbin of computer history? Bring it back to life by writing a simulator for it.
