I am not calling anyone a liar.
I know. You're cool. I just want to sort this out because there's a lot of confusion regarding release dates as we get older and newcomers repeat hearsay.
Here's another news clipping dating the Duo's release to Fall of '92:
Go to the Turboplay archives and browse by year, read any article from '92 and all they talk about is the upcoming TurboDuo and the founding of TTI.
SCD games didn't even exist in the U.S. until 1992. This can be verified by the copyrights. You won't find any SCD magazine coverage until 1992. Gate of Thunder won the EGM Editor's Choices Gold in the November 1992 issue. The games they reviewed were occasionally a month or two old, but not a year. The first EGM Buyers' Guide to feature the Duo was the 1993 issue. The Duo's box features Air Zonk and Air Zonk wasn't released until 1992. I could go on, but I think you get the idea.
Maybe you're mixed up because school years span calendar years? I don't know.
I do remember looking at the label on the box and thinking it was very odd the serial was dated 92. No idea why though.
It wasn't just the box, the bottom of each system bears a date of manufacture.
