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.
