 I don't rememebr a lunar lander for it (there's a very famous one
 for the
 DEC GT40 terminal...), but anyway.

 Oh, there quite probably was. The HP9830 is not a 'natural' for this
 sort
 of thing because there was no graphical output as standard. I suppose
 you
 could link up an HP1350 graphics translator (HPIB was available for the
 9830 -- in fact I think it was the first desktop machine to have that
 interface), but it wasn't a commonly-done thing. 
 
The thermal line printer was a pretty standard piece of equipment with
the 9830, and it was a quick printer. One could do character-based
graphics with it.
In 1976 my high school had a 9830, it was the first machine I
programmed (still have the exercise program listings). At the same time
I was soldering up boards for a friend assembling an IMSAI. I recall
Lunar Lander from the day, and playing it on one or the other, but
couldn't say for sure which.
  On the otehr hand there were lunar lander games for
many of the HP
 handheld calcualtors with 1-line numeric displays. Something like that
 could certainly run on a 9830.

 I will take a look. I assume it's in BASIC, and given that the
 programming manuals and the manuals for the optional ROMs are available
 it shouldn't be too hard to translate it to a more modern BASIC.
