SG-1000 II
In July 1984, Sega released an updated version of the console called the SG-1000 II. It is functionally identical to the SG-1000, 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. In Japan 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. Card based software was exclusive to Japan, only cartridge based games were released in Europe and Oceania.
The Card Catcher would become built into the Sega Mark III, as well as the first version of the Master System.
