A home computer was a class of personal computers entering the market in 1977 and becoming common during the 1980s. These computers typically cost much less than business, scientific or engineering-oriented desktop personal computers of the time, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business personal computers, and was usually sold for purposes of education, game play, and personal productivity use such as word processing. Advertisements for early home computers were rife with possibilities for their use in the home, from cataloging recipes to personal finance to home automation, but these were seldom realized in practice as they usually required the home computer user to learn how to program; a significant time commitment many weren't willing to make.

The home computer became affordable for the general public due to the mass production of the microprocessor. In contrast to their predecessors, which had front-mounted switches and blinkenlights to control and indicate internal system status and often came in kit form, home computers were designed to be used by the average consumer, not necessarily an electronics hobbyist. These machines were pre-assembled, with keyboards and plug-in peripheral devices such as screens, cassette tape recorders, joysticks, and (later) disk drives. Usually the manufacturer would provide all the peripheral devices practical to add to any system as extra cost accessories. Often peripherals were not interchangeable between brands of home computer (or sometimes even between successive models of the same brand).

Background

After the success of systems like the RadioShack TRS-80, the Commodore PET and the Apple Inc. Apple II in 1977, large numbers of new machines of all types began to appear during the late 1970s and early 1980s. Some home computers sold many units over several years, such as the BBC Micro, Sinclair ZX Spectrum, Atari 800XL and Commodore 64, and attracted third-party software development.

To some extent, low-end home computers competed with video game consoles. The markets weren't entirely distinct, as both had the ability to be used for games. A common marketing tactic was to show a computer system and console playing games side by side, then emphasising the computer's greater ability by showing it running user-created programs, educational software, word processing, spreadsheet and other applications while the game console showed a blank screen or continued playing the same repetitive game. Books were available for most models of computer with titles along the lines of "64 Amazing BASIC Games for the Commodore 64" and were a popular means of both learning to program and software distribution. Some video game consoles offered "programming packs", consisting of a version of BASIC in a ROM cartridge. The ColecoVision console even had an expansion module which converted it into a full-fledged Coleco Adam computer system. During the peak years of the home computer market, scores of models were produced, usually with little or no thought given to compatibility between different manufacturers or even within product lines of one manufacturer. The concept of a computer platform did not exist, except for the Japanese MSX standard. The Nintendo GameCube is an example of a popular video game console. ...

The introduction of the IBM Personal Computer in August 1981 would eventually lead to standardization in personal computing, largely due to the system's open architecture, which encouraged production of third-party clones of the unit. While the Apple II would be quickly displaced by the IBM PC for office use, Apple Computer's 1984 release of the Apple Macintosh created a new model for the home computer which IBM-compatible computers would eventually imitate.

The declining cost of IBM-compatible "personal computers" on the one hand, and the greatly increased graphics, sound, and storage capabilities of dedicated video game consoles on the other, caused the market segment for home computers to vanish in the early 1990s in the US. In Europe, the home computer remained a distinct presence for a few years more, with the Amiga and Atari ST lines being the dominant players, but today a computer purchased for home use anywhere will be very similar to those used in offices - made by the same manufacturers, with compatible peripherals, operating systems, and application software.

Many home computers were superficially similar. Most had a keyboard integrated into the case; sometimes a cheap-to-manufacture chiclet keyboard in the early days, although full-travel keyboards quickly became universal due to overwhelming consumer preference. Most systems could use an RF modulator to display 20–40 column text output on a home television. The use of a television set as a display almost defines the pre-PC home computer. Although monitors dedicated for use with a computer were available for this market segment, it was often a later purchase only made after users had bought a floppy disk drive, printer, modem, and the other pieces of a full system. This "peripherals sold separately" approach is another defining characteristic of home computers. Many first time computer buyers brought a base C-64 system home to find they needed to purchase a disk drive or Datassette before they could make use of it.

In the early part of the 1980s, home computers were mostly based on 8-bit microprocessor technology, typically the MOS Technology 6502 or the Zilog Z80. A notable exception was the TI-99 series, announced in 1979 with a 16 bit TMS9900 CPU. 8-bit refers to the number of bits used in the data bus of a computer. ...

Processor clock rates were typically 1-2 MHz but this aspect of performance was not emphasized by users or manufacturers, as dealing with the systems' limited RAM capacity, graphics capabilities and storage options took priority. Clock speed was considered a technical detail of interest only to users needing accurate timing. To economize on component cost, often the same crystal used to produce color television compatible signals was also divided down and used for the processor clock. This meant processors rarely operated at their full rated speed, and had the side-effect that European and North American versions of the same home computer operated at slightly different speeds and different video resolution due to different television standards. The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers or transferring a value from one processor register to another. ...

Many home computers initially used the ubiquitous compact audio cassettes as a storage mechanism. Most implementations were notoriously slow and unreliable, but floppy disk drives found on more costly business-oriented microcomputers were expensive and used disks eight inches wide at the beginning of the home computer era. Costs declined toward the end of the 1980s as sales of microcomputers increased and large production of 5.25" drive mechanisms enabled economy of scale. The 5.25" floppy disk drives would become standard, with 3.5" drives being made available for most systems toward the latter part of the decade. Most software for home computers remained sold on 5.25" disks, however; 3.5" drives were used for data storage. Standardization of disk formats was not common; sometimes even different models from the same manufacturer used different disk formats. Various copy protection schemes were developed for floppy disks but most were broken in short order, and many users would only tolerate them for games as wear and tear on disks was a significant issue in an entirely floppy-based system, and having a backup disk of vital application software was seen as important. Copy programs that advertised their ability to copy or even remove common protection schemes were a common category of utility software. Typical 60-minute Compact Cassette. ...

In contrast to modern computers, home computers most often had their OS stored in ROM chips. This made startup times very fast - no more than a few seconds but made upgrades difficult or impossible without buying a new unit. Usually only the most severe bugs were fixed by issuing new ROMs to replace the old ones at the user's cost. The user interface was usually only a BASIC interpreter coupled to a character-based screen or line editor, with applications performing all other OS duties themselves. As multitasking was not common on home computers until late in the '80s, this lack of API support wasn't much of a liability. Application programs usually accessed hardware directly to perform a specific task, often "switching out" the ROM based OS to free the address space it occupied. In an enduring reflection of their early cassette-oriented nature, most home computers loaded their Disk Operating System (DOS) separately from the main OS. The DOS was only used to send commands to the floppy disk drive and needn't be loaded to perform other computing functions. One notable exception was Commodore, whose disk drives actually contained a 6502 processor and Commodore DOS in ROM. Many home computers also had a cartridge interface which accepted ROM-based software. This was occasionally used for expansion or upgrades such as fast loaders, and application software on cartridge did exist, but the vast majority of cartridges were games.

From about 1985, the high end of the home computer market began to be dominated by "next generation" home computers using the 16-bit Motorola 68000 chip, which helped to enable the greatly increased abilities of the Amiga and Atari ST series. Clock rates on these systems were approximately 8 MHz with RAM capacities of 256 kB (for the base Amiga 1000 system) up to 1024 kB (1 megabyte, a milestone, first seen on the Atari 1040 ST).

Radio frequency interference

After the first wave of computers landed in American homes, the US Federal Communications Commission began receiving complaints of interference to television reception. By 1979 the FCC demanded that home computer manufacturers submit samples for radio frequency interference testing. It was found that "first generation" home computers, which often included their own screens, emitted too much radio frequency noise for household use. Some manufacturers appealed to the FCC to waive the requirements for home computers, while other manufacturers (with compliant designs) objected to the waiver. Many manufacturers had to supply an external RF modulator to allow their units to connect to a home television receiver.[citation needed] Eventually techniques to suppress interference became standardized. The abbreviation FCC can refer to: Face-centered cubic (usually fcc), a crystallographic structure Federal Communications Commission, a US government organization Farm Credit Corporation/Farm Credit Canada, a Canadian government organization Families with Children from China, an adoption support organization Florida Christian College, a college in central Florida Fresno City...

"The Home Computer Revolution"

In the late 1970s and early 1980s, from about 1977 to 1983, it was widely predicted[1] that computers would soon revolutionize many aspects of home and family life as they had business practices in the previous decades. Mothers would keep their recipe catalog in computer databases and turn to a medical database for help with child care, fathers would use the family's computer to manage family finances and track automobile maintenance (note the gender roles). Children would use disk-based encyclopedias for school work and would be avid video gamers. Home automation would bring about the intelligent home of the '80s. Using some sort of computer technology, television would be interactive. Morning coffee would be brewed automatically under computer control. The same computer would control the house lighting and temperature. Robots would take the garbage out, and be programmable to perform new tasks by the home computer. Electronics were expensive, so it was generally thought that each home would have one computer for the entire family to use, with interfaces to the various devices it was expected to control.

All this was predicted to be commonplace sometime before the end of the decade, but virtually every aspect of the predicted revolution would prove not to be or be delayed. Put simply, the computers available to consumers of the time period just weren't powerful enough to perform any single task required to realize this vision, much less do them all simultaneously. The home computers of the early 1980s could not multitask. Even if they could, memory capacities were too small to hold entire databases or financial records, floppy disk-based storage was woefully inadequate in both capacity and speed for true multimedia work, and the graphics of the systems could only display blocky, unrealistic images and blurry, jagged text. Before long, a backlash set in—computer users were "geeks", "nerds" or worse, "hackers". The North American video game crash of 1983 soured many on technology in general. The computers that were purchased for use in the family room were either forgotten in closets or relegated to basements and children's bedrooms to be used exclusively for games and the occasional book report.

It took another 10 years for technology to mature, for the graphical user interface to make the computer approachable for non-technical users, and for the internet to provide a compelling reason for most people to want a computer in their homes. Predicted aspects of the revolution were left by the wayside or modified in the face of an emerging reality. The cost of electronics dropped precipitously and today many families have a computer for each family member, or a laptop for mom's active lifestyle, a desktop for dad with the kids sharing a computer. Encyclopedias, recipe catalogs and medical databases are kept online and accessed over the world wide web not stored locally on floppy disks or CD-ROM.

This delay wasn't out of keeping with other technologies newly introduced to an unprepared public. Early motorists were widely derided with the cry of "Get a horse!"[2] until the automobile was accepted. Television languished in research labs for decades before regular public broadcasts began. In an example of changing applications for technology, before the invention of radio, the telephone was used to distribute opera and news reports, whose subscribers were denounced as "illiterate, blind, bedridden and incurably lazy people".[3] Likewise, the acceptance of computers into daily life today is a product of continuing refinement of both technology and perception.

As many older computers have become obsolete and in some cases nonfunctional, it has become popular amongst enthusiasts[4] to virtually "recreate" these machines, their environments and popular software titles[5] with emulation software. One of the more well known emulators is the Multiple Emulator Super System which can emulate most of the better known home computers. One system for which many emulators exist is the MSX. A more or less complete list of home computer emulators can be found here. Games for many 8 and 16 bit platforms are becoming available for the Wii Virtual Console.
