Vintage Computer
A vintage computer is an older computer system that is largely regarded as obsolete. The personal computer has been around since around 1971, and in that time technological advancement means existing models get replaced every few years. Nevertheless, these otherwise useless computers have spawned a sub-culture of vintage computer collectors who often spend large sums for the rarest examples, not only to display but functionally restore. This involves active software development and Retrocomputing, adaptation to modern uses. This often includes Homebrew (video games), homebrew developers and Hacker (hobbyist), hackers who add on, update and create hybrid composites from new and old computers for uses they were otherwise never intended. Ethernet interfaces have been designed for many vintage 8-bit machines to allow limited connectivity to the Internet, where users can access discussion groups, bulletin boards, and software databases. Most of this hobby centers on History of computi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcomputer Collection 2
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes Computer memory, memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframe computer, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a Computer keyboard, keyboard and Computer monitor, screen for input and output) are also personal computers (in the generic sense). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A "microcomputer" ...

Apple II Peripheral Cards
An apple is a round, edible fruit produced by an apple tree (''Malus'' spp.). Fruit trees of the orchard or domestic apple (''Malus domestica''), the most widely grown in the genus, are cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, '' Malus sieversii'', is still found. Apples have been grown for thousands of years in Eurasia before they were introduced to North America by European colonists. Apples have cultural significance in many mythologies (including Norse and Greek) and religions (such as Christianity in Europe). Apples grown from seeds tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the ...

Apple II
Apple II ("apple Roman numerals, two", stylized as Apple ][) is a series of microcomputers manufactured by Apple Computer, Inc. from 1977 to 1993. The Apple II (original), original Apple II model, which gave the series its name, was designed by Steve Wozniak and was first sold on June 10, 1977. Its success led to it being followed by the Apple II Plus, Apple IIe, Apple IIc, and Apple IIc Plus, with the 1983 IIe being the most popular. The name is trademarked with square brackets as Apple ][, then, beginning with the IIe, as Apple //. The Apple II was a major advancement over its predecessor, the Apple I, in terms of ease of use, features, and expandability. It became one of several recognizable and successful computers throughout the 1980s, although this was mainly limited to the US. It was aggressively marketed through volume discounts and manufacturing arrangements to educational institutions, which made it the first computer in widespread use in American secondary ...

Apple I
The Apple Computer 1 (Apple-1), later known predominantly as the Apple I, is an 8-bit personal computer designed by Steve Wozniak and released by the Apple Computer Company (now Apple Inc.) in 1976. The company was initially formed to sell the Apple I its first product and would later become the world's largest technology company. The idea of starting a company and selling the computer came from Wozniak's friend and Apple co-founder Steve Jobs. A differentiator of the Apple I was that it included video display terminal circuitry, allowing it to connect to a low-cost composite video monitor and keyboard instead of an expensive accompanying terminal. The Apple I and the Sol-20 were some of the earliest home computers to have this capability. To finance the Apple I's development, Wozniak and Jobs sold some of their possessions for a few hundred dollars. Wozniak demonstrated the first prototype in July 1976 at the Homebrew Computer Club in Palo Alto, California, impre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOS Technology 6502
The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") William Mensch and the moderator both pronounce the 6502 microprocessor as ''"sixty-five-oh-two"''. is an 8-bit computing, 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design. When it was introduced in 1975, the 6502 was the least expensive microprocessor on the market by a considerable margin. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as the 6800 or Intel 8080. Its introduction caused rapid decreases in pricing across the entire processor market. Along with the Zilog Z80, it sparked a series of projects that resulted in the home computer microcomputer revolution, revolution of the early 1980s. Home video game consoles and home com ...

Motorola
Motorola, Inc. () was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded by brothers Paul and Joseph Galvin in 1928 and had been named Motorola since 1947. Many of Motorola's products had been radio-related communication equipment such as two-way radios, consumer walkie-talkies, cellular infrastructure, mobile phones, satellite communicators, pagers, as well as cable modems and semiconductors. After having lost $4.3 billion from 2007 to 2009, Motorola was split into two independent public companies: Motorola Solutions (its legal successor) and Motorola Mobility (spun off), on January 4, 2011. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers.

SWTPC 6800
The SWTPC 6800 Computer System, simply referred to as SWTPC 6800, is an early microcomputer developed by the Southwest Technical Products Corporation and introduced in 1975. It was built around the Motorola 6800 microprocessor, from which it gets its name. The SWTPC 6800 was one of the first microcomputers based around the Motorola 6800. The SWTPC 6800 is the progenitor of the widely used and broadly supported SS-50 bus. The SWTPC 6800 became one of the most popular 6800-based systems of its time, owing to its ease of use and ample documentation. Though rudimentary, the MIKBUG resident monitor built into ROM allows the immediate entry of program data after power-up, as opposed to other microcomputers of its day which required bootstrapping such software. Southwest Technical Products introduced the SWTPC 6800 in November 1975 for US$450 () in kit form only. Any contemporary ASCII terminal can be used to interface with the SWTPC 6800. SWTPC sold their own television-set-based te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SWTPC
Southwest Technical Products Corporation, or SWTPC, was an American producer of electronic kits, and later complete computer systems. It was incorporated in 1967 in San Antonio, Texas, succeeding the Daniel E. Meyer Company. In 1990, SWTPC became Point Systems, before ceasing a few years later. History In the 1960s, many hobbyist electronics magazines such as ''Popular Electronics'' and ''Radio-Electronics'' published construction articles, for many of which the author would arrange for a company to provide a kit of parts to build the project. Daniel Meyer published several popular projects and successfully sold parts kits. He soon started selling kits for other authors such as Don Lancaster and Louis Garner. Between 1967 and 1971, SWTPC sold kits for over 50 ''Popular Electronics'' articles. Most of these kits were intended for audio use, such as hi-fi, utility amplifiers, and test equipment such as a function generator based on the Intersil ICL8038. Many of these early ...
