Sorta related,
During the birth of the 16 Bit era, I was reading up on both the TurboGrafx 16 and the Genesis. After a bit of research I decided the one that was coming out with a CD Rom add-on would be the coolest one to get. I was reading about the TG-16, but when I looked at the Genesis I saw the round top and thought that was a CD clamshell. So I asked for that one thinking it would play disks.
It was the wrong system I had in mind but I had a darn good run with it. especially after finding out how much the Turbo CD cost.
