One of our website goals is to centralize as many old systems’ documentation as possible. A lot of people contact us because they have an old system but don't know how to use it, lacking relevant documentation. Thus, we try here to provide links to all documentation available for each system. When a link is broken and the resource is no longer available, we will host this documentation on our server so the archiving effort is not lost.

You can help us on this task in many ways: sending us links to new documentation, scanning/OCR/archiving new documentation, or reporting to us any broken links. For more info, please contact us.
