Recently, after reading Where Wizards Stay Up Late: The Origins Of The Internet, I was struck with the strangest desire. Though I've never been a fan of computer games, I found the burning need to play Adventure, the original computer game, in a version as close to the original by Will Crowther (or the second version by Don Woods) as possible. Now, I was actually able to find the close-to-original source online and download it. However, it was written in the original FORTRAN for the DEC PDP-10. Being that I don't have space for a room-sized computer, or the funds to buy and restore one (there are probably still a few running out there), I decided that there are two possibilities: 1) Get a PDP-10/FORTRAN emulator for Linux, and take the easy way out. 2) Make a real project of it, and port the original FORTRAN source to x86 Linux.
I was able to grap the original source as a .tar.gz archive.
So, here are some links of interest, and when I finally finish, I will publish my results.
PDPplanet.com has an extensive computer history site mostly about PDPs including a user community, photos, restoration stories, and a great links section. To top it off, the site's owner, Paul G. Allen, has a running DEC PDP-10 2065 (PDPplanet DECsystem-10 TOPS-10 v7.04), which you can login to via telnet at DEC-10.PDPplanet.com
 TS10 is a project at SourceForge that emulates PDP-10, PDP-11, and VAX. SIMH, of the Computer History Simulation Project, is capable of simulating a wide variety of historical hardware, from PDPs to Honeywell H316/H516s (the machines that worked as IMPs on the first computer network, ARPANET and many more.
