History & Development
In July 1984, Sega released an updated version of the console called the SG-1000 Mark II. It is functionally identical to the Mark I, but has a re-styled shell and the connector for the optional plug-in SK-1100 keyboard has been moved from the rear to the front. It was initially priced at ¥15,000. A computer version of this console, with a built-in keyboard, was called the SC-3000, which would go on to outsell the SG-1000.
The SG-1000 runs all SC-3000 games and applications, with the exception of Music and Basic Cartridges. The machine could be used just like the SC-3000, provided one had the keyboard attachment ready. The console also had an optional game card reader add-on called the Card Catcher that allowed for the use of Sega game card software.
The Card Catcher would become built into the SG-1000 Mark III, as well as the first version of the Sega Master System.
