The SC-3000 is a computerised version of the SG-1000 console. If a keyboard sold separately is added to the console, then it becomes an SC-3000. Released in 1983, it is the only computer to be fully designed and manufactured by Sega.
The computer was only released in Japan at least by Sega, though a select few countries, such as France, New Zealand and Australia did get the machine, though through other companies.
The machine is sought after today, as it is able to play all SG-1000 cartridges, and unlike the console, it has composite out, so can be used worldwide, with a stepdown, or correctly wired local PSU.
The machine has two joystick ports like the Mark II Sg-1000, where as the SG-1000 original model, which has one joystick wired in.
This is the first model with the rubberised keyboard, later the SC-3000H was released, which has full travel keys. Most machines are black in colour, though there are rarer white and red ones.
The BASIC for the machine comes on a cartridge, which also (except for BASIC Level II) add more RAM to the machine, anything up to 48K.
The Computer is said to have sold much better than the SG-1000 console, but was soon superceded by other micros such as the MSX computers.
Although not widely known in the west, it does have a loyal following.
