The rgb input is a Japanese 21-pin connector that ends in an 8-pin mini din. The 21-pin connector is the same design as SCART, but the pinout is different. I found a hardwired cable online where someone has made the same modifications, but what's the fun in that.
Actually, Santa probably didn't pay retail (it was a gift) for the Xmas holiday season.
My post is not a review, as there are several excellent ones on the web.
