Hewlett Packard HP-97 Calculator - Playing the Moon Rocket Lander Game 

Thank you for this great series / playlist

These machines were amazingly powerful for the time. Expensive too, but considering they were really Turing-complete computers with scientific functions built in and a whole application ecosystem, they were a bargain compared to your other options.

My very first computer game! 😊

This looks cool!

very cool....i would love to see more of those magnetic strip programs as well...and reading out of the hp book was good too!!

What other games or applications does this calculator had that used magnetic card.
