PdpVia DiggPaul Allen has donated his collection of ancient DEC computers to this site. Program like its 1972! “PDPplanet.com offers users something unique–the ability to telnet to a DECsystem-10 or an XKL Toad-1, log in to a personal account, create or upload programs, and run them. We encourage enthusiasts at all levels of experience, beginners and old hands alike, to apply for accounts on the 2065 (running Tops-10 v7.04) and the Toad-1 (running Tops-20 v7.1) and to visit the PDP Planet Forums to share ideas and ask questions.” Link.
