Yeah, the Aztec's and Mayan's did it too... Didn't require a computer.
Aztecs, Mayans marveled at eclipses — and predicted them with precision
I wonder if we used any of their knowledge or just re-discovered how to do that in more modern times.
The Babylonians and the Mayans independently discovered the Saros Cycle of 18 years and 10 days. Successive eclipses in each cycle are quite stable with respect to latitude, shape of path and length of totality. Unfortunately the longitude shifts 1/3 of the way around the world west each time. So these civilizations could predict the date of an eclipse but not its precise timing or where it might be total. It required Kepler and Newton's understanding of astrophysics and calculus to improve upon that.

This was my 11th total solar eclipse and Liz O'Mara's 9th. We met online via common interest in skiing and eclipse chasing in July 2010. Unfortunately she lived in NY and was skiing in Chile after seeing the eclipse on Easter Island while I was skiing in New Zealand after viewing from the
Paul Gauguin cruise ship off Tahiti. We met in person when her NYC ski club came to Mammoth in March 2011, and the rest is history. She moved to LA in 2013 and we have seen the last 5 eclipses together.
Before we knew of each other, we independently wanted to see the 2017 eclipse from the top of the Jackson Hole Ski Resort at 10,450 feet. We began pestering the resort in 2014 and they finally developed a plan for the tram a year ago. We organized tram tickets for 57 people and lodging in Teton Village for about half of them.
We did not take our Tesla on this trip due to the lengthened travel time from SoCal and the possibility we might have to drive some distance east or west on short notice if Jackson's weather forecast was unfavorable. As it was, only 40 of us went up the tram because Idaho's forecast was a slam dunk while ours was maybe 75% clear. But the scattered clouds moved through quickly and it was all clear on the mountain from about 9:30AM.
In July Liz and I thought this would be the most appropriate time and place to get married, but it took until August 6 before we found a retired judge to officiate. We were filmed by the Weather Channel.
We were also featured in a write-up for

I did not see this thread until today. I was active on ski forums urging people to get into the totality zone and persuaded perhaps 10 of them to do so. I'm pleased this thread was effective in getting the word out too. We love our Tesla and use it for 3/4 of our driving including most ski trips to Mammoth. But this was a scenario where it could cause delays and complications, not chances we were willing to take.
We were also in Yellowstone for 5 days after the eclipse, spending 4 nights at Canyon Lodge. One night I saw an X75D from Ontario plugged into a 110V outlet near the front desk. There's a more patient traveler than we are! I inquired and found out that Old Faithful and Mammoth Hot Springs are the only locations in the park with 220V charging. The other lodging locations are supposed to get them by next summer. I do think that the West Yellowstone Supercharger makes travel within the park viable, particularly since the speed limit is 45mph.
