Section 1. Introduction

Thank you for choosing to read The SG-1000/SC-3000 FAQ. Why these machines? They are very 
interesting. The games I have played seem to surpass games for other systems from the early 
1980s. Also the fact that they were never released in the States (my home) make them more 
exotic.

Section 2. System By System

2.1 SG-1000 - The SG-1000 was the very first system ever released by Sega in 1983. Its main 
market was Japan. It did find it's way into Australia (distributed by John Sands), New Zealand 
(distributed by Grandstand Leisure, Ltd.), and some parts of Europe. The price for the system 
in Japan was 15,000 Yen. It ran on a 4mbit processor with 64k ram and played 2 musical 
instruments at once. In Japan, there was a clone system from Tsukuda Original called the 
Othello Multivision. Tsukuda released a series of games including Q*Bert and
James Bond 007. A second model of the SG-1000 was made called the SG-1000 II.

2.2 SC-3000 - The SC-3000 was Sega's home computer (yes, they did make computers at one point). 
It was pretty much an SG-1000 game system at heart. It worked with software from both machines.

Section 3. The Coleco/Sega/MSX Connection

The SG-1000/SC-3000 machines and the Colecovision seemed to be based on the MSX computer system. 
They shared technical specs and some MSX games appeared on the Colecovision (
Antarctic Adventure, Cabbage Patch Kids) and some SG-1000 games (GP World, Zoom 909) appeared 
on the MSX. Just something to note.

Section 4. The Games and Software

There were quite a few games released for the SG-1000 in its 3-year existence. There was not 
quite as much "official" software for the SC-3000 because it did not last as long. They may 
have been software made by individual users, though.

Section 5. Peripherals

There were some optional equipment available for the SC-3000 computer.

16 Kb RAM expansion cart
Disk drive (3" micro disk)
Joystick; It was white and similar to a Colecovision controller (but without the keypad: it was 
very long). Also it had 2 red keys (one on the right side, one on the left side...) 
Printer

Section 6. Where can I get me some SG-1000 and SC-3000 stuff?

To our readers from Japan, Australia, New Zealand, and Europe, you have more of a chance of 
finding stuff than anyone else. Just look around.

To our American readers, forget about it. They were never released here. So on American 
sites and in American stores, you'll most likely come up with nothing. Maybe foreign sites will 
have something. Maybe even foreign stores, if you're a world traveler.
