I was familiar with a couple of variants of this console: the original Japanese PC Engine from 1987 and the American version from 1989 called TurboGrafx-16. I have the version intended for the European market, simply called TurboGrafx, from 1990: it was based on the American model, with a few adjustments to make it work with the PAL standard. The launch of the console in Europe was cancelled, and those already produced were sold to various distributors.
