PDP Unix Preservation Society Home Page

The PDP Unix Preservation Society (PUPS), part of The Unix Heritage Society, is devoted to the preservation of all information related to the versions of Unix that ran on Digital PDPs. If you have something that you think should be preserved, or if you have any experience with PDP Unix, please let us know! Much of the information we are trying to preserve is protected by copyright or by licensing. We strive to abide by these conditions.
