The SG-1000, also known as Sega Game 1000, was a third-generation 8-bit home video game console released by Sega on July 15, 1983, and had a Zilog Z80 CPU at 3.58 MHz with 1 KB of RAM. This system marked Sega's first entry into the home video game hardware business. The SG-1000 didn't see much success in its home country, mostly due to competition from the technically superior Famicom. It did, however, enjoy a brief period of popularity in Taiwan before the latter market was inundated by unlicensed Family Computer clones.

Sega's use of off-the-shelf components in developing the console, which was also shared with the ColecoVision, led to at least one unauthorized clone of the SG-1000, manufactured and sold by Taiwan-based Bit Corporation as the Dina 2-in-1. Indeed, the Dina had support for SG-1000 games and ColecoVision titles to a certain extent.

The SC-3000 (also known as Sega Computer 3000) was its home computer counterpart and has a built-in keyboard.

Sega Graphic Board[edit]

Also known as Terebi Oekaki. Includes a graphic board attached to a cartridge. Can be used on SG-1000, SC-3000, Sega Mark III, and Japanese / Korean models of Master System. Another version made for the International Master System models was planned to be released.

MEKA supports both variants of the Graphic Boards.

Keyboard[edit]

Named Sega Keyboard SK-1100. It essentially adds some of the missing features of the SC-3000 to an SG-1000 or Sega Mark III. It is not compatible with the Japanese / Korean models of Master System due to pinout differences in their respective expansion ports.

Kega Fusion, Meka, and MAME support this keyboard.

Othello Keyboard[edit]

A built-in keyboard found in Othello Multivision, an SG-1000 clone from Tsukuda Original. It is solely used to play the Othello variant of the game used as a BIOS. It cannot be used with the stand-alone version of Othello for SG-1000, which was distributed as a common cartridge.

Meka and MAME support this special keyboard.

Floppy Disk Drive[edit]

Known as Super Control Station SF-7000. Allows the SC-3000 to use 3" (proprietary format) floppy disks manufactured by Sega. Not widely popular due to their high retail price (¥79,800). It also includes its own IPL (BIOS), as the SC-3000 does not include any kind of built-in software, unlike MSX computers.

MEKA, Kega Fusion, and MAME support reading disk images, although is unknown if they allow data writing to them.

HyperShot[edit]

Cross-compatible two-button controller manufactured by Konami to be used in any piece of hardware that uses DE-9 ports. On SG-1000, it is used with Hyper Sports, although it can be used with the bootleg conversions of Hyper Olympic / Sports games from MSX1 on Sega Mark III / Master System.

Data Recorder SR-1000[edit]

Datacorder that allows common cassette tapes to be read and written with the BASIC software from SG-1000 or SC-3000. On SG-1000 (or Sega Mark III), the presence of a SK-1100 is required. On standard SG-1000 games, it can be used on:

  • C-So!
  • Championship Lode Runner
  • Lode Runner

MAME supports reading and writing cassette tape images. blueMSX also had planned tape support for their SC-3000 driver as well.

Modem[edit]

A modem used for SC-3000 manufactured by John Sands, released only in Australia. It allows a special software named SegaCom to be connected to the Internet through dial-up. The modem connects itself in the cartridge port, in the same vein as connecting a Model 2 Sega CD to a Sega Genesis.

No known emulator supports this, and the SegaCom ROM is not dumped.

Handle Controller & Bike Handle[edit]

Known as SR-400 and BH-400, both are driving controllers compatible with the following games:

  • GP World
  • Hang-On II
  • Monaco GP
  • Safari Race
  • Zippy Race
  • Zoom 909

No emulators support these controllers for now.

RAM Adapter[edit]

An 8KB RAM Adapter to be used in SG-1000, sold only in Taiwan without a license from Sega. It allows certain MSX1 conversions to be played on the system.

Genesis Plus GX, MEKA, and MAME do support this accessory as a form of cartridge mapper.

Arcade[edit]

Sega also used the SG-1000 hardware to run Arcade games. Here's a known list of Arcade games:

  • Champion Boxing
  • Champion Pro Wrestling
  • Doki Doki Penguin Land
  • Super Derby
  • Super Derby II

The first three games are pretty much the same as their SG-1000 counterparts, but Super Derby and Super Derby II are special medal-type games intended to be used with 1-9 players. MAME features full support for the common SG-1000 Arcade games, but for the Derby ones, it is still preliminary.
