As many know (or not?) the cables between the Duo Tap and Turbo Tap can be swapped to allow a Duo tap to work on a Turbografx 16 and vice versa. I swapped these out so that I could plug multiple controllers like the Avenue 6 into my TG16. Of course I had a Turbo Tap and a Duo Tap cable left over after this, so I created the "Hybrid Tap"! It plugs into your DUO and allows TG16 controllers to work on it. I do not need it, and am looking for $10 plus shipping for anyone that wants it.
I also have two very nice condition (brand new looking) TG16 original controllers, two official 6FT extension cables, and one Turbo Tap (unmodified regular model) for sale. I would like to sell it all off in one shot for about $50, but could break it up if someone wanted some of it.
I accept paypal payments only. PM if interested!
