TurboGrafx-CD / Turbo Duo
The TurboGrafx-CD is the North American version of the PC-Engine CD add-on which was released for the TurboGrafx. The PC Engine CD was originally released in Japan on October 30, 1987. It was the first console system to play CD games.
The North American version was released on August 29, 1989. The system released at $399.99, which made it a tough sell to consumers. On top of that, the system was also very difficult to find for the gamers who were willing to pay that much. A system card (version 2.0) was required by some CD games and needed to be inserted into the TurboGrafx card slot before playing those CD games. The add-on released with no games packed in. Launch titles included Wonder Boy III: Monster Lair and Fighting Street (Street Fighter).
Because of the lack of the success for the TurboGrafx-CD, a combo system entitled the Turbo Duo was released for a lower price. This system also included the version 2.0 system card built in. The system which played both the Turbo Chips and the CD games retailed for $300. The original Turbo Duo system included one controller, an AC adapter, RCA cables, Ys Book I & II, a CD-ROM2 title, and a Super CD disc including Bonk's Adventure, Bonk's Revenge, and Gate of Thunder. Even at the dropped price, consumers found the system too expensive, and NEC later included a pack-in disk with several additional games, as well as a coupon book, but sales still did not pick up.
Unlike the Turbo Chips, the TurboGrafx-CDs didn't have any region protection, which allowed Japanese games to be played on a North America system without any modifications. This proved to be very handy as once again hundreds of CD titles were released in Japan that never made it out in North America. The only CD games not available for play were the Arcade CDs, which required the Arcade system card (version 3.01), which wasn't made available in North America.
