Oh, did anyone have a Turbo Graphix 16?
A friend of mine's parents bought him one back in 1990 when the thing was state of the art, better than Nintendo. But it was still technically an 8-bit system. The games were fun, but it didn't have mascot recognition (i.e., Mario). It just had the Bonk's Adventure games (which were admittedly OKAY).
It didn't sell well, and my little brother got one for Christmas a couple years later when it got marked down in price. Still a fun system to play.
