The PC Engine is a video game console released by NEC, a Japanese company, in 1987. The system was released in 1989 as TurboGrafx 16 for the North American market. A PAL version of the system also saw a very limited release in the UK and continental Europe in 1990 as "Turbografx" (sans the "16" in the title).
Super CD-ROM²[]
In 1991, NEC introduced an upgraded version of the CD-ROM² System known as the Super CD-ROM², which updates the BIOS to Version 3.0 and increases buffer RAM from 64kB to 256kB. This upgrade was released in several forms: the first was the PC Engine Duo on September 21, a new model of the console with a CD-ROM drive and upgraded BIOS/RAM already built into the system. This was followed by the Super System Card, released on October 26, an upgrade for the existing CD-ROM² add-on that serves as a replacement to the original System Card. PC Engine owners who did not already own the original CD-ROM² add-on could instead opt for the Super-CD-ROM² unit, an updated version of the add-on released on December 13 which combines the CD-ROM drive, interface unit and Super System Card into one device.
