Tremendous, thank you so much. I’m out of town on a film shoot, but when I return I’ll download them right away. The computer simulation is kinda cool too!

I also found a publication from the ARRL, "Getting to know Oscar from the ground up" published in 1977.  It describes how to use the Oscarlocator.    All you needed was the EQX, equator-crossing information that was provided by the W1AW bulletins and you could predict AOS and LOS for Oscar 6 or 7.  Pretty neat stuff at the time.
