Take a detailed look at the Konami QTa adapter, a very obscure piece of Famicom history

Here's a piece of hardware about the Famicom you've most likely never heard of. Way back in the day, Konami made something called a QTa adapter, which was an accessory for the Famicom to play carts made by Konami and Japanese media giant NHK. There weren't many games made for the accessory, outside of some educational games.

If you're curious to learn more about this odd accessory, the video above is an absolute goldmine of details. Not only does it show off the QTa adapter, but a handful of games as well! The video might be in Russian, but just click over to English subs and you're good to go!
