That's awesome! I'd love to have that kind of paperwork for my family's original Intellivision but all of that, and the system itself, is long gone. What is amazing to me is just how much we were paying for video game systems even back then. The prices for consoles have barely changed in 40 years, $270-$300 range. The difference is, with inflation, we actually pay far less now for a modern system. Your total from that receipt in today's money is $964!
