Living Computer Museum is a portal into the past—a Web site that examines the early roots of the computing industry through rare artifacts from the Paul G. Allen collection of Digital Equipment Corporation (DEC) mainframes and minicomputers.

Pride of place is given to three PDP-10 systems: a publicly accessible 2065, a 1090, running the Tops-10 operating system, and a 2020 originally owned by the MIT Artificial Intelligence Lab, which runs their Incompatible Timesharing System. In addition to these, the historic DEC collection houses a number of PDP-11 and PDP-8 minicomputers, and a PDP-10 clone, the XKL Toad-1 System running the TOPS-20 operating system. The collection also contains many image files for DEC computers, and a large library of manuals that will be placed online.

This historic information is available through the Web site with descriptions of the restoration process and recommendations for how others can leverage this work for their own projects.
