Ah, yes... the Oscarlocator. Why I remember back in the day when...
I'll spare you all, except to say that if I recall correctly, once the correct
overlay was
selected, we would take nothing more than two pieces of data, the time of an
ascending equator crossing
(EQX abbreviation comes to mind),
I believe an older (1989-90) edition of the Amateur Satellite Handbook had
the map on the inside back cover, and overlays that could be copied from the
pages.
Of course someone would have to create the overlays for more recent satellites.
