This is a port of "The Valley" game to the HP Prime calculator. It was developed and tested on a "G2" model and I cannot guarantee that it will run correctly on an earlier version.
The original version was printed as a program listing in the April 1982 edition of Computing Today magazine for the Commodore PET.
The game appeared on a number of other systems over the years, such as the VIC-20, C-64, Spectrum, etc and I figured the HP Prime, with its 320x240 display, would be an ideal target.
Here you will find:
- The original back-story from the magazine.
- Installation/upgrade instructions.
- How to play the game.
- An explanation of how the parts of the program work with hints at how it could be extended.
