This wiki is an experiment to create a means for knowledgeable people to enter their information into some kind of a knowledge base. This is however, not the relatively formalized tone and style imposed by Wikipedia. Sentences starting with "I seem to recall" are perfectly welcome here - and articles do not have to be in the descriptive, encyclopedic style Wikipedia enforces. On the contrary, it is preferred that many of the articles be references, guides, helpful hints, suggestions, tutorials and so on.

If you have any information you want to contribute to this wiki, please, contribute it. We'd much rather remove or modify a dozen potentially unsuited submissions than miss out on a single good one. We hope this wiki grows into a useful resource for everyone interested in classic computing, no matter what their level of knowledge may be; it is meant to be all-encompassing. -- Tore & Lucky

The Software Preservation Group (SPG) of the Computer History Museum is exploring how to collect software in support of the museum's overall mission.

The work of the SPG includes:

   Preserving and collecting software
   Identifying and working with other people preserving and collecting software
   Sponsoring and assisting software preservation and collection activity

This web site is used to:

   communicate and coordinate the activities of the SPG
   display the works-in-progress
   solicit assistance from potential volunteers and collaborators

Use the tabs above to find information about the SPG, our current projects, SPG meetings, and how you can help.
