Sega is a
video gamedeveloper,
publisher, and
hardware development company headquartered in
Tokyo,
Japan, with multiple offices around the world. The company's involvement in the
arcade game industry began as a Japan-based distributor of coin-operated machines, including
pinball games and
jukeboxes.[1][2][3] Sega imported second-hand machines that required frequent maintenance. This necessitated the construction of replacement guns, flippers, and other parts for the machines. According to former Sega director Akira Nagai, this is what led to the company into developing their own games.[4]
Sega released Pong-Tron, its first video-based game, in 1973.[5] The company prospered from the
arcade game boom of the late 1970s, with revenues climbing to over US$100 million by 1979.[6] Nagai has stated that Hang-On and Out Run helped to pull the arcade game market out of the
1983 downturn and created new genres of video games.[4]
In terms of arcades, Sega is the world's most prolific arcade game producer, having developed more than
500 games,
70 franchises, and 20
arcade system boards since 1981. It has been recognized by
Guinness World Records for this achievement.[7] The following list comprises the various arcade system boards developed and used by Sega in their arcade games.
Arcade system boards
Before Lindbergh, Sega arcade hardware was either proprietary or built on gaming console architecture. Nowadays, arcade hardware closely resembles gaming PCs, with recent models even incorporating embedded versions of Microsoft Windows.
Introduced
arcade conversion kits where games could be changed in 15 minutes via a card cage housed in game cabinet with six PC boards; kits were sold as Convert-a-Game paks or ConvertaPaks[13]
Uses ROM boards, with optional
GD-ROM compatible
CD-ROM drive.[113][118] If a drive is used, it will be used at bootup to copy data to a DIMM RAM board instead.[119]
Naomi multiboard can use 3 or 4 boards at the same time depending on the game[120][121][122][123]
Based on
GameCube architecture.[144] Supported GameCube memory cards.[145]
The idea for Triforce came from Namco and Sega. They saw potential in the GameCube architecture for a cost-effective and port-friendly arcade machine. Nintendo agreed to cooperate in building the Triforce board, but had little interest in developing arcade games of their own.[146]
Sega has developed and released additional arcade games that use technology other than their dedicated arcade system boards. The first arcade game manufactured by Sega was
Periscope, an
electromechanical game. This was followed by Missile in 1969.[189] Subsequent video-based games such as Pong-Tron (1973), Fonz (1976), and
Monaco GP (1979) used
discrete logic boards without a CPU microprocessor.[190]Frogger (1981) used a system powered by two Z80 CPU microprocessors.[191] Some titles, such as Zaxxon (1982) were developed externally from Sega, a practice that was not uncommon at the time.[192]
