YM2203
The YM2203, a.k.a. OPN (FM Operator Type-N), is a six-channel (3 FM and 3 SSG) sound chip developed by Yamaha. It was the progenitor of Yamaha's OPN family of FM synthesis chips used in many video game and computer systems throughout the 1980s and early 1990s. It was used in a variety of NEC computers, along with various arcade game machines. The YM2203 and the rest of the OPN synthesizer family generate sound via frequency-modulated digital sine waves. It included 12 operator "cells", each generating a 13-bit sine wave at a programmable frequency, the volume of which is controlled by a programmable ADSR envelope generator. The output of these cells could be either summed together by the mixer, or fed into the input of another cell, in 4-cell batches creating the final sound values or "channels". 4 operator cells per channel allowed a total of 8 different permutations of cell connections, known as "algorithms". The ADSR parameters, multiplier and detune settings for each opera ...

NEC PC-9801
The , commonly shortened to PC-98 or , is a lineup of Japanese 16-bit and 32-bit personal computers manufactured by NEC from 1982 to 2000. The platform established NEC's dominance in the Japanese personal computer market, and, by 1999, more than 18 million units had been sold. While NEC did not market these specific machines in the West, it sold the NEC APC series, which had similar hardware to early PC-98 models. The PC-98 was initially released as a business-oriented personal computer which had backward compatibility with the successful PC-8800 series. The range of the series has expanded, and in the 1990s it was used in a variety of industry fields including education and hobbies. NEC succeeded in attracting third-party suppliers and a wide range of users, and the PC-98 dominated the Japanese PC market with more than 60% market share by 1991. IBM clones lacked sufficient graphics capabilities to easily handle Japan's multiple writing systems, in particular kanji with its tho ...

Space Harrier
is a third-person arcade rail shooter game developed by Sega and released in 1985. It was originally conceived as a realistic military-themed game played in the third-person perspective and featuring a player-controlled fighter jet, but technical and memory restrictions resulted in Sega developer Yu Suzuki redesigning it around a jet-propelled human character in a fantasy setting. The arcade game is controlled by an analog flight stick while the deluxe arcade cabinet is a cockpit-style win electric motors motion simulator cabinet that tilts and rolls during play, for which it is referred as a ''taikan'' (体感) or "body sensation" arcade game in Japan. It was a commercial success in arcades, becoming one of Japan's top two highest-grossing upright/cockpit arcade games of 1986 (along with Sega's '' Hang-On''). Critically praised for its innovative graphics, gameplay and motion cabinet, ''Space Harrier'' is often ranked among Suzuki's best works. It has made several cr ...

Hang-On
is an arcade racing game released by Sega in 1985 and later ported to the Master System. In the game, the player controls a motorcycle against time and other computer-controlled bikes. It was one of the first arcade games to use 16-bit graphics and uses the Super Scaler arcade system board, created with design input from Yu Suzuki, as technology to simulate 3D effects. The deluxe cabinet version also introduced a motion-controlled arcade cabinet, where the player's body movement on a large motorbike-shaped cabinet corresponds with the player character's movements on screen. Yu Suzuki began development of ''Hang-On'' after deciding to design a motorcycle racing game as a way to use a torsion bar in an arcade game. With market research suggesting GP 500 racing was popular, Suzuki took inspiration from world champion Freddie Spencer and his style of racing. The game's soundtrack was written by Hiroshi Kawaguchi, who used rock music that was uncommon in arcade games at the ...

Fujitsu FM-7
The FM-7 ("Fujitsu Micro 7") is a home computer created by Fujitsu. It was first released in 1982 and was sold in Japan and Spain. It is a stripped-down version of Fujitsu's earlier FM-8 computer, and during development it was referred to as the "FM-8 Jr.". Although it was designed to be a cut-down version of the FM-8 (with the FM-7 costing 126,000 yen, compared to 218,000 yen for the FM-8), most notably removing the (expensive) bubble memory technology, the FM-7 was given a more advanced AY-3-8910 sound chip capable of three voice sound synthesis, leading to a strong uptake among the hobbyist computer market in Japan and making it a more popular system than the FM-8. The FM-7 primarily competed with the NEC PC-8801 and Sharp X1 series of computers in the early 1980s. It was succeeded by the FM-77 series of computers in 1984, which featured backwards compatibility with the FM-7. The FM-77 series was later succeeded by the 32-bit FM Towns in 1989. The FM-7 is based around th ...
