Sega SG-1000

The Sega Game 1000, more commonly known as the SG-1000, was Segas first home video games console. It was famously released for ¥15,000 in Japan on July 15, 1983. Unfortunately, the Nintendo Famicom was released the same day for ¥14,800; Talk about bad luck!!

Not only was the Famicom released with amazing games like the arcade port Donkey Kong, it was also vastly superior from a technical point of view. The console did enjoy some success though and was sold in Australia, New Zealand and various parts of Europe. It was never released in North America though.

The original SG-1000, known as the Mark I, had a good looking, refreshing design. It was pretty simplistic with a cartridge slot on the top and a power button on the front. A hard-wired controller was connected to the back of the console.

The controller had a joystick in the middle and a button at either side. Most people remember this controller as being tough to move and unresponsive.

A year after launch (1984), Sega released a redesigned version of the SG-1000 called the SG-1000 II (known as the Mark II). It was practically the same as the Mark I console from a functionality point of view except there was a connection port which allowed you to connect to a SK-1100 keyboard.

The controller was no longer hard-wired and there was an additional port to accommodate a second controller. The joystick was replaced by controllers which were very similar to the Famicoms.

SG-1000 II

A computer version of the SG-1000 with a built in keyboard was released around the same time as the Mark II. It was known as the SC-3000 and managed to outsell both SG-1000 consoles. Games from the SC-3000 could be played on the SG-1000 except from certain music and programming applications.

Sega also released an accessory called the Card Catcher around the same time they released their redesigned SG-1000. The Card Catcher would allow users to play Sega Game Card software. This add on was included in the Mark III, which was later known worldwide as the Sega Master System.

The release of the Mark III signalled the end of Segas first home games console.


The SG-1000 used a clone of the popular Zilog Z80 CPU (NEC 780C), which was clocked around 3.58 Mhz. It had 16kb of RAM and 128kb of VRAM.

It used a Texas Instruments TMS9928A graphics chip to display up to 16 colours in it’s 256×192 pixel resolution. It also had a Texas Instruments SN76489 to produce 4 channels of mono sound. The whole system was technically identical to the ColecoVision, which was released in North America in 1982.

The Mark 1 system had one controller hard wired to it. The Mark II had two ports for detachable controllers to be connected.
