The original PDP-1 SpaceWar! had an accurate starfield, termed the Expensive Planetarium. I want to add the same thing to SpaceWar! 7800. So far I've translated the Yale star information into quincunx sampled tile lists. The current annoyance is the X/Y position to DL entry code. It's not hard code, just annoying and tedious, and I don't seem to have the necessary desire & drive.
