He also bought one for my brother Ernie. This was not as nearly as powerful as an HP-67 (or the TI-59 my brother Neil had), but it was a wonderful first "computer" for me and my brother. Since we both had the same model we had a lot of opportunity to work together on games and other things.
These calculators came with very good instructional books and also a pad of program sheets where you would write down all program steps and explain what the program was for and how to use it. Great stuff.
Some of the sorts of programs we created did things like:
- Compute primes
- Plot curves
- Artillery games
- Lunar lander
- Number guessing games
