The Sega Genesis is a fourth-generation video game console developed and produced by Sega. It was originally released in Japan in 1988 as Mega Drive (メガドライブ Mega Doraibu?), then in North America in 1989 as Sega Genesis, and in Europe, Australia and other PAL regions in 1990 as Mega Drive.

The reason for the two names is that Sega was unable to secure legal rights to the Mega Drive name in North America. The Sega Genesis is Sega’s third console and the successor to the Sega Master System with which it has backward compatibility when the separately sold Power Base Converter is installed.

The console was released in Japan as Mega Drive on October 29, 1988. Sega announced a North American release date for the system (as Sega Genesis) on January 9, 1989. Sega initially attempted to partner with Atari Corporation for distribution of the console in the US, but the two could not agree to terms and Sega decided to do it themselves. Sega was not able to meet the initial release date and US sales began on August 14, 1989 in New York City and Los Angeles. The Sega Genesis was released in the rest of North America later that year on September 15, 1989 with the suggested retail price of $189.99, $10 less than originally planned, and also $10 less than the competing TurboGrafx-16.

The Mega Drive’s CPU is a 16/32-bit Motorola 68000. The maximum addressable memory is 16 MB from the ROM ($00000000-00400000 – 4 MB), to the RAM ($00FF0000-00FFFFFF – 64 KB). The 68000 runs at 7.61 MHz in PAL consoles, 7.67 MHz in NTSC consoles. The Mega Drive also includes a Zilog Z80, which serves as secondary processor along with allowing complete Master System compatibility with only a passive adapter. The initial Mega Drive models used a Hitachi-made HD68HC000, while the Mega Drive 2 and later models used a Motorola MC68HC000, both fabricated in CMOS.

Many thanks to Fabio D. Bovelacci for his donation. This is my second computer (ZX-81 is the first one), i spent a significant portion of my childhood in front of this one.

from old-computers.com homepage:

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 MasterSystem II was originally designed to output an RF modulated (VHF) signal but with a mod you can get a better signal with the Composite Video .

Description:

• Country: Japan
• Most Common: Usa/Europe
• Rarity: Unrare
• Year: 1990

from Wikipedia:

The Sega Master System is an 8-bit cartridge-based video game console that was manufactured by Sega and was first released in 1986.^[3] Its original Japanese incarnation was the Sega Mark III (although the “Master System” name has also been used in Japan).

In the European market, this console launched Sega onto a competitive level comparable to Nintendo, due to its wider availability, but failed to put a dent in the North American and Japanese markets. The Master System was released as a direct competitor to the NES/Famicom.
