I obtained the required formulas from a library book, wrote the program, entered it into my HP-25, plugged it into AC power and away I went.

In the early 80's, I too made a program to locate geosynchronous satellites and find their Azimuth And Elevation. But for the 41C. I used the formulas form an old astronomy book.
