                <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>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 moz-do-not-send="true"
