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 Japanese yen, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FM-8
The FM-8 (Fujitsu Micro 8) is a personal computer developed and manufactured by Fujitsu in May 1981. It was Fujitsu's second microcomputer released to the public after the LKIT-8 kit computer, and the first in the "FM" series. The FM-8 was an early adopter of bubble memory technology. The FM-8 would later be replaced by two new models in November 1982 – the FM-11, aimed at businesses and the FM-7 aimed at the mass market.

FM Towns
The is a Japanese personal computer, built by Fujitsu from February 1989 to the summer of 1997. It started as a proprietary PC variant intended for multimedia applications and PC games, but later became more compatible with IBM PC compatibles. In 1993, the FM Towns Marty was released, a game console compatible with existing FM Towns games. The "FM" part of the name means "Fujitsu Micro" like their earlier products, while the "Towns" part is derived from the code name the system was assigned while in development, "Townes". This refers to Charles Townes, one of the winners of the 1964 Nobel Prize in Physics, following a custom of Fujitsu at the time to code name PC products after Nobel Prize winners. The e in "Townes" was dropped when the system went into production to make it clearer that the term was to be pronounced like the word "towns" rather than the potential "tow-nes". History Fujitsu decided to release a new home computer after the FM-7 was technologically overcome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NEC PC-8801
The , commonly shortened to PC-88, are a brand of Zilog Z80-based 8-bit home computers released by Nippon Electric Company (NEC) in 1981 and primarily sold in Japan. The PC-8800 series sold extremely well and became one of the three major Japanese home computers of the 1980s, along with the Fujitsu FM-7 and Sharp X1. It was later eclipsed by NEC's 16-bit PC-9800 series, although it still maintained strong sales up until the early 90s. NEC's American subsidiary, NEC Home Electronics (USA), marketed variations of the PC-8800 in the United States and Canada. History Nippon Electric's Microcomputer Sales Section of the Electronic Device Sales Division launched the PC-8001 in September 1979, and by 1981 it consisted of 40% of the Japanese personal computer market. In April 1981, Nippon Electric decided to expand personal computer lines into three groups: New Nippon Electric, Information Processing Group and Electronic Devices Group, with each specializing in a particular series.

Motorola 6809
The Motorola 6809 ("''sixty-eight-oh-nine''") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes. Among the most powerful 8-bit processors of its era, it was also much more expensive. In 1980 a 6809 in single-unit quantities was compared to for a Zilog Z80 and for a 6502. It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature competitiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OS-9
OS-9 is a family of real-time, process-based, multitasking, multi-user operating systems, developed in the 1980s, originally by Microware Systems Corporation for the Motorola 6809 microprocessor. It was purchased by Radisys Corp in 2001, and was purchased again in 2013 by its current owner Microware LP. The OS-9 family was popular for general-purpose computing and remains in use in commercial embedded systems and amongst hobbyists. Today, OS-9 is a product name used by both a Motorola 68000-series machine language OS and a portable (PowerPC, x86, ARM, MIPS, SH4, etc.) version written in C, originally known as OS-9000. History The first version ("OS-9 Level One"), which dates back to 1979–1980, was written in assembly language for the Motorola 6809 CPU, and all of its processes ran within the 64KB address space of the CPU without a memory management unit. It was developed as a supporting operating system for the BASIC09 project, contracted for by Motorola as part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AY-3-8910
The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit General Instrument CP1600, CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's ''Gyruss'' contains five—and pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge for the TRS-80 Color Computer. After General Instrument's spinoff of Microchip Technology in 1987, the chip was sold for a few years under the Microchip brand. It was also manufactured under license by Yamaha Corporation, Yamaha (with a selectable clock divider pin and a double-resolution and double-rate volume envelope table) ...

Sharp X1
The , sometimes called the Sharp X1 or CZ-800C, is a series of home computers released by Sharp Corporation from 1982 to 1988. It is based on a Zilog Z80 CPU. The RGB display monitor for the X1 had a television tuner, and a computer screen could be super-imposed on TV. All the TV functions could be controlled from a computer program. The character font was completely programmable (PCG) with 4-bit color, and was effectively used in many games. The entirety of the VRAM memory was mapped on to the I/O area, so it was controlled without bank switching. These features made the X1 very powerful for game software. Development Despite the fact that the ''Computer Division'' of Sharp Corporation had released the MZ series, suddenly the ''Television Division'' released a new computer series called the X1. At the time the original X1 was released, all other home computers generally had a BASIC language in ROM. However the X1 did not have a BASIC ROM, and it had to load the Hu-BASIC ...

TRS-80 Color Computer
The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer and sometimes nicknamed the CoCo, is a line of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different, incompatible system and a radical departure in design and compatibility with its Motorola 6809E processor rather than the Zilog Z80 earlier models were built around. The Tandy Color Computer line started in 1980 with what is now called the Color Computer 1. It was followed by the Color Computer 2 in 1983, then the Color Computer 3 in 1986. All three models maintain a high level of software and hardware compatibility, with few programs written for an older model being unable to run on the newer ones. The Color Computer 3 was discontinued in 1991. All Color Computer models shipped with Color BASIC, an implementation of Microsoft BASIC, in ROM. Variants of the OS-9 multitasking operating system were availab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragon 32/64
The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., initially in Swansea, Wales before moving to Port Talbot, Wales (until 1984) and by Eurohard S.A. in Casar de Cáceres, Spain (from 1984 to 1987), and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively. Product history Dragon Data entered the market in August 1982 with the Dragon 32. The Dragon 64 followed a year later. The computers sold well initially and attracted the interest of independent software developers including Microdeal. A companion magazine, ''Dragon User'', began publication shortly after the microcomputer's launch. Despite this initial success, there were two technical impediments to the Dragon's acceptance.

Arcade Games
An arcade game or coin-op game is a coin-operated entertainment machine typically installed in public businesses such as restaurants, bars and amusement arcades. Most arcade games are presented as primarily games of skill and include arcade video games, Pinball machines, electro-mechanical games, redemption games or merchandisers. Types Broadly, arcade games are nearly always considered games of skill, with only some elements of games of chance. Games that are solely games of chance, like slot machines and pachinko, often are categorized legally as gambling devices and, due to restrictions, may not be made available to minors or without appropriate oversight in many jurisdictions. Arcade video games Arcade video games were first introduced in the early 1970s, with ''Pong'' as the first commercially successful game. Arcade video games use electronic or computerized circuitry to take input from the player and translate that to an electronic display such as a monitor or telev ...
