That reminds me of the "Space Travel" game/sim that Ken Thompson wrote for
the first copy/iteration of Unix.
Did anyone ever actually run/see that? There are some screenshots online

I'm really curious to know how Ken & Dennis approched it, and how far off
from today's crazy graphics interfaces was it.
I was just looking at that graphics system; Multics had a monitor system
called XRAY that could see into memory and display live data on a PDP-8
with a 338 display. Looking at the space war source, it seems that it used
an earlier iteration of the 338, but with the same basic architecture. It
was a vector graphics display, the controller reading a command list from
memory consisting on X/Y/intensity values being fed to ADCs connected an
oscilloscope or monitor.
I have some code that does an X-11 emulation of the Atari Tempest vector
graphics display; I'm thinking of wedging it into the simh PDP8 code to
emulate the 338 and PDP-1 displays.
DECUS has PDP-8 software that runs on the 338, and the spacewar source is
available, so that should be emulatable as well.
