TurboGrafx CD
NEC's CD-ROM add-on for its PC Engine / TurboGrafx-16 console. Originally released as the PC Engine CD-ROM in Japan in 1988, this was the first system to use the CD-ROM format. It would later be released in North America as the TurboGrafx-CD in 1989. While it had little impact on the ailing TurboGrafx-16 in North America, this add-on boosted PC Engine sales in Japan.
