Looking for HP-65 Moon Rocket Landing Simulator (#00287A)

[David Hayden]

A while back, I wrote a Datafile article describing some bugs in the HP-29C lunar lander program. The article traced the history and legacy of the program.

At the time, I found references to HP-65 versions in the PPC journal. A few days ago, I found reference to the subject program in HP-65 Key Notes Vol. 2 Number 2 on page 4. This Key Note article's description makes it appear nearly identical to the 29C version, except that the 65 version starts with twice as much fuel that burns with half as much force.

Does anyone know where I can find a listing of the HP-65 program? The title is Moon Rocket Landing Simulator and it is #00287A in the HP-65 Users' Library.

Gene has a listing of a HP65 lunar lander game that appeared in PPC Journal vol. 2 number 3 page 34 (March 1975). I don't know if this is the program you are looking for, and maybe you already found this version, but since there is a tiny chance... ;-)

If this is not the desired program: This version is somewhat different from other lunar lander games. It seems to include a random number generator and the user may specify a "professional mode" by setting a flag. Maybe a similar version could go into the 67 fun ROM v2 ?-)

Hey Dieter!

Consider a 67 version of that HP-65 lunar lander a candidate for the 67FUN2 rom. ;-)

It looks like this is a different program, but thanks for the reference!
