Home computers were a class of microcomputers that entered the market in 1977, that started with what Byte Magazine called the "trinity of 1977", (the Apple II, the TRS-80 Model I, and the Commodore PET) and which became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as the IBM PC,and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were playing video games, but they were also regularly used for word processing, doing homework, and programming.
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board. Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive. Many microcomputers are also personal computers.
The Apple II is an 8-bit home computer, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak. It was introduced in 1977 at the West Coast Computer Faire by Jobs and was the first consumer product sold by Apple Computer, Inc. It is the first model in a series of computers which were produced until Apple IIe production ceased in November 1993. The Apple II marks Apple's first launch of a personal computer aimed at a consumer market – branded towards American households rather than businessmen or computer hobbyists.
The TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy/Radio Shack, Z-80 microprocessor. It is one of the earliest mass-produced and mass-marketed retail home computers.
Home computers were usually not electronic kits; home computers were sold already manufactured in stylish metal or plastic enclosures. There were, however, commercial kits like the Sinclair ZX80 which were both home and home-built computers since the purchaser could assemble the unit from a kit.
An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions and often a printed circuit board (PCB) or another type of prototyping board.
The Sinclair ZX80 is a home computer launched on 29 January 1980 by Science of Cambridge Ltd.. It is notable for being the first computer available in the United Kingdom for less than a hundred pounds. It was available in kit form for £79.95, where purchasers had to assemble and solder it together, and as a ready-built version at £99.95. The ZX80 was very popular straight away, and for some time there was a waiting list of several months for either version of the machine.
Advertisements in the popular press for early home computers were rife with possibilities for their practical use in the home, from cataloging recipes to personal finance to home automation,but these were seldom realized in practice. For example, using a typical 1980s home computer as a home automation appliance would require the computer to be kept powered on at all times and dedicated to this task. Personal finance and database use required tedious data entry.
Personal finance is the financial management which an individual or a family unit performs to budget, save, and spend monetary resources over time, taking into account various financial risks and future life events. When planning personal finances, the individual would consider the suitability to his or her needs
