I was hugely into videogames until around 1983 or 1984. Post-5200, I still paid attention to arcade games, but never had any interest in the SMS or NES and stopped paying attention to home systems for a long time. So I had no idea the 7800 even existed until seeing an index card on a bulletin board at college in 1989. I bought some guy's system, with 9 cartridges for it.

Frankly, I found the 7800 to be a pretty boring system. I did enjoy Xevious on it though.
