Mark III

The Sega Mark III is the third version of the SG-1000 system and was only released in Japan. This system is in fact the original Japanese version of the Sega Master System.

Compared to the SG-1000 Mark II the case has been redesigned again, a video monitor output has been added, and the system is equiped with a card slot which was also found on the first version of the Master System. The Mark III is backwards compatible with the SG-1000 cartridges.

The system has an expansion port that can be used by add-ons, such as the FM sound unit or the Telecon Pack (wireless video signal). The controllers (two joypads), can still be stored on each side of the system. Many other add-ons were available (not using the expansion port though), such as several different controllers, 3D Glasses, keyboard, graphic board, etc.

When Sega decided to market the Mark III abroad they redesigned the case and sold it as the Sega Master System. Though superior technically, the SMS/Mark III was eclipsed by the great success of the NES/Famicom.

We need more info about this console ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.

Hey Peder I actually have two of these now, it is a cool machine so light and small and quite stylish but the RGB output is quite dark for some reason unless the one I have been playing on is faulty.. nice machine..
