The Sega SC-3000 Computer & SG-1000 Console were Sega's first foray into the world of home videogames and were introduced around 1983.

Both units saw very little distribution outside Japan and as a result very little is known about them.   However the machines were reasonable sellers in two overseas markets , Australia & New Zealand (& sold in South Africa, Italy, Spain)

In New Zealand the distribution was handled by Grandstand Leisure Ltd who supported the system up until early 1986 when they dropped the Sega line to concentrate on marketing the Amstrad range in NZ.
In Australia the line was marketed by "John Sands"

In both countries a small but strong & enthusiastic user base developed. In addition to the "official" Cartridges & Tapes sold by Grandstand (and later distributors)
a variety of other Applications & Games were sold by a number of small New Zealand & Australian developers. (all were on Tape or Disk - no 3rd Party Cartridges were ever produced).
Some 3rd party hardware was also produced, including a Speech Synthesis unit (developed by a local NZ company) & a Lightpen.

In New Zealand a magazine was also produced for a number of years "Sega Computer - The official magazine of the SEGA User Club of New Zealand".

In New Zealand & Australia the the SC-3000 far outsold the SG-1000. The SC-3000 was marketed as a programmers/beginneers computer NOT a games system.
The SG-1000 was advertised as a machine that would let your kids play Sega games on the TV and leave the SC-3000 free so you could get with some serious programming.
