The National Museum of Toys and Miniatures is a smallish museum in Kansas City, Missouri on the campus of the University of Missouri – Kansas City. Admission was only $5 [https://toyandminiaturemuseum.org/].
I took photos of all of the game systems they had on display. You can see this at:

The first system they had was the 1972 Odyssey. What I enjoyed seeing was the handheld "Football 2" which I wore the buttons almost off when I was an undergraduate in the early 1980s.
