“TurboGrafx-16 (original)” (1987-1992?/94?)

The original USA version of the PC Engine, branded as the TurboGrafx-16. This is the vastly more common version for the TurboGrafx-16 in the USA. It has some clunky features, such as the need for excessive addons (memory cards, saving, controller taps) to fully experience certain games. Recognizable by it’s obvious lack of a CD tray, plus a large card recess on the top right. Large expansion port on the back, that is identical to the Japanese PC Engine expansion port. Only has RF out, with only one controller port (extras require a tap). Very large.

“TurboDuo” (1992-1995)

Feature-wise, one could say this is the ultimate TurboGrafx-16. While still a “version” of the TurboGrafx, the TurboDuo practically crams 3 addons into one device. This console can be easily recognized by it’s all black finish and it’s CD tray. Included is the functions of the original TurboGrafx-16, the functions of the TurboGrafx-CD, an updated BIOS for Super CD discs, more RAM, and a smaller controller port (identical to Japanese controller ports). Said smaller port requires an adapter for peripherals tailored for the larger port of the original TurboGrafx-16. The one lost feature is the expansion port, which cannot be found on this console.
