PDP Planet
Paul Allen (of Microsoft fame) has put up a web site for his collection of Digital Equipment Corporation mainframes and minicomputers. The collection has a real history, some pretty pictures, and the ability to telnet to a DECsystem-10 or an XKL Toad-1 and actually use them. Serious cool nerd factor.


My dad just reminded me that I still have a Compaq luggable 8086 in his attic (as part of my distributed computer collection.)
I dug around on the site and he has a link to Gordon Bell’s stuff (GB was the CTO of Digital for many years). He has a bunch of old manuals, including for the PDP-1 from 1960. Particularly interesting for VCs — Digital was the biggest success of the “founder” of venture capital, Georges Doriot, and the PDP-1 was their first product. (Note that GB is now at MS).
