Spacewar was before text Startrek on the DEC PDP's?</div></blockquote><div><br></div><div>Spacewar! dates to 1962 on the DEC PDP-1, which predates even Star Trek: TOS. It was later ported to a few other PDPs, including the PDP-8 (well, the LAB-8, which had a point-plot display, a basic requirement for the game), the PDP-7, PDP-10 and PDP-11, and other non-DEC systems as well. </div><div><br></div><div>The version I'm assembling on a PDP-8/E was written sometime in the early 1970s, I believe. It will be connected to a large oscilloscope display, and I've already constructed period controllers for the game. The goal was to stay with period hardware, which I'm staying pretty true to. I just got through fixing the extended math boards (hardware multiply/divide) last night, as documented here: <a href="http://imgur.com/a/QVRLs">imgur.com/a/QVRLs</a></div><div><br></div><div>That's a neat story with the Cray YMP.
