The SC-3000 is a computer based on the hardware of the first videogame systems released by Sega in Japan : the SG-1000 series. It can use the same game cartridges marketed for these consoles.
The SC3000 can't be used without a ROM cartridge, which can be either a game or language. There were three different BASIC cartridges. One came with only 1Kb of RAM (and you had only 512 bytes free !), the second with 16Kb and the last with 32Kb. In official adverts, they show a total RAM of 48Kb. This was counting the VRAM and the 32Kb BASIC cartridge...
Several great games were adapted by Sega for this computer. Several graphic characteristics of the SC-3000 are fairly close to MSX ones. For example, it was one of the first computers to offer 32 sprites.
Some months later, Sega released the SC-3000 H which was the same system but with a mechanical keyboard.
This computer was also marketed by Yeno under the same name (Yeno SC 3000 & SC 3000H). It was exactly the same computer except for the Yeno brand...

The Sega computer was sold in Australia by John Sands, a religious retailer of non-gambling card and board games.
It was one of the main sellers, and was nipping at the heels of the Commodore 64 in sales in Chistmas ''84. Commodore and Amstrad were the main home computers at the time, the other manufacturers like Atari and Sinclair didn''t appear to have much interest in the Australian market.
Sega got into a row with John Sands over the Master System, which they wanted Sands to sell, but they refused because it didn''t have any educational value. John Sands took them all the way to the High Court and won an injunction preventing Sega from selling the Master System - so Sega stopped the supply of SC-3000s to John Sands !
So, potentially the biggest computer in Australia basically withered away in 1986, leaving the entire market to Commodore...
