I played the graphics lunar lander on a PDP-9 with a
graphics display
 and push buttons (not the sw) in a back room in the Kiewit Computation
 Center at Dartmouth in like 1972 or 1973, the same time I was playing
 it in text on a teletype ASR-33 in Focal.  Hand typed in and punched
 to paper tape.

 Lander, in FOCAL? The only one I know is for the GT40, in assembler.

 Apparently the original version was in FOCAL.

 Interesting.  And amazingly short.
 I flipped through some of those articles.  There's a version from
 around those early times not mentioned, for the CDC 6000 mainframe
 computer.  It used the console display, dual green text displays that
 could also do graphics (clumsily, because the API was a dot drawing
 one, not line vectors).
 What's unusual about that one is that it's a pilot's point of view
 display -- it shows you the lander's instruments and a view out the
 windows, rather than an outside observer view as the GT40 version
 does.  I played it a few times, it was hard -- I never managed to
 land it.  One of the system staff (at University of Illinois PLATO
 project) was rumored to have a fast way to land: flip upside down,
 blast rockets, flip right side up, blast some more for a soft landing.
