[amsat-bb] InstantTrack or similar usable on Win 10

[tjschuessler at verizon.net]

I was wanting to describe to some folks I am doing a satellite demonstration
for next week, about how some satellites have stable sun-synchronous orbits
while others process earlier each day.  The old DOS program, InstantTrack,
that most likely will not work under the Windows 10/64 bit world had a nice
display of this behavior,   Are there any recommendations for a more modern
application that will do the same type of thing?  If you are not familiar
with what I am talking about, look at page SO-3 in the current "Getting
Started." book from AMSAT (As well as on earlier pages) to see what I am
looking for.  A web search shows that it should be in the AMSAT software
archives but the page link for that particular software is broken.  It is a
nice planning utility, especially for birds that do change times each day.
