RE: Programming Handheld Calculators
Well that brings back fond memories. The program that Paul Lutus submitted to Popular Electronics magazine (Space Flight) really fired my imagination with what could be done with a programmable calculator. I had been saving for almost two years and was already planning to buying my HP-25 in June 1977 on my 16th birthday. This article in Popular Electronics (which came out in May) just added to the fever. After I bought my HP-25 I ended up playing with Paul's program for hours plotting the orbits around various sized planets. Looking back it was a magical time in my life.
