Whilst the SuperGrafx was largely failing in the market, NEC kept pushing the PC Engine platform.  One of it’s various versions (and my personal favourite) was the PC Engine Duo.

The Duo took the PC Engine and combined it, in one sleek package, with the SuperCD addon.  It was certainly successful in terms of hardware, the unit was far more convenient than the previous add on units had been and was very reliable.

The Duo was also released in North America as the TurboDuo but never made it to Europe.
