The TurboDuo, the American version of the PC Engine Duo, was released by NEC and Hudson Soft in 1991 and was a rather sleek combination of the TurboGrafx-16 and its CD add-on in a single unit. Despite being able to play both HuCards and CDs the console --probably due to its hefty price-tag-- didn't do particularly well and is nowadays quite the rarity.
Now, provided you know how to fix its CD-drive (I've been told this isn't too difficult to do) this Turbo Duo eBay auction, might just be the thing for you. The console comes complete in its box and with six games including Splatterhouse, Bonk's Adventure and Bloody Wolf.
