<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"

<div>That's a neat story with the Cray YMP. Too bad you
don't still have it. </div>
