Apple I Computer
The Apple Computer 1, originally released as the Apple Computer and known later as the Apple I or Apple-1, is an 8-bit desktop computer released by the Apple Computer Company (now Apple Inc.) in 1976. It was designed by Steve Wozniak. The idea of selling the computer came from Wozniak's friend and Apple co-founder Steve Jobs. The Apple I was Apple's first product, and to finance its creation, Wozniak sold his HP-65 calculator for $500 and Jobs sold a second hand VW Microbus, for a few hundred dollars (Wozniak later said that Jobs planned instead to use his bicycle to get around). Wozniak demonstrated the first prototype in July 1976 at the Homebrew Computer Club in Palo Alto, California. Production was discontinued on September 30, 1977, after the June 10, 1977 introduction of its successor, the Apple II, which ''Byte'' magazine referred to as part of the "1977 Trinity" of personal computing (along with the PET 2001 from Commodore Business Machines and the TRS-80 Model I from ...

Steve Wozniak
Stephen Gary Wozniak (; born August 11, 1950), also known by his nickname "Woz", is an American electronics engineer, computer programmer, philanthropist, inventor, and technology entrepreneur. In 1976, with business partner Steve Jobs, he co-founded Apple Computer, which later became the world's largest technology company by revenue and the largest company in the world by market capitalization. Through his work at Apple in the 1970s and 1980s, he is widely recognized as one of the most prominent pioneers of the personal computer revolution. In 1975, Wozniak started developing the Apple I into the computer that launched Apple when he and Jobs first began marketing it the following year. He primarily designed the Apple II, introduced in 1977, known as one of the first highly successful mass-produced microcomputers, while Jobs oversaw the development of its foam-molded plastic case and early Apple employee Rod Holt developed its switching power supply.

Homebrew Computer Club
The Homebrew Computer Club was an early computer hobbyist group in Menlo Park, California, which met from March 1975 to December 1986. The club had an influential role in the development of the microcomputer revolution and the rise of that aspect of the Silicon Valley information technology industrial complex. Several high-profile hackers and computer entrepreneurs emerged from its ranks, including Steve Jobs and Steve Wozniak, the founders of Apple Computer. With its newsletter and monthly meetings promoting an open exchange of ideas, the club has been described as "the crucible for an entire industry" as it pertains to personal computing. History The Homebrew Computer Club was an informal group of electronic enthusiasts and technically minded hobbyists who gathered to trade parts, circuits, and information pertaining to DIY construction of personal computing devices. It was started by Gordon French and Fred Moore who met at the Community Computer Center in Menlo Park. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 revolution of the early 1980s. Popular video game consoles and home computers of the 1980s and early 1990s, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOS Technology
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), later known as CSG (Commodore Semiconductor Group) and GMT Microelectronics, was a semiconductor design and fabrication company based in Audubon, Pennsylvania. It is most famous for its 6502 microprocessor and various designs for Commodore International's range of home computers. History Three former General Instrument executives, John Paivinen, Mort Jaffe and Don McLaughlin, formed MOS Technology in Valley Forge, Pennsylvania in 1969. The Allen-Bradley Company was looking to provide a second source for electronic calculators and their chips designed by Texas Instruments (TI). In 1970 Allen-Bradley acquired a majority interest in MOS Technology. In the early 1970s, TI decided to release their own line of calculators, instead of selling just the chips inside them, and introduced them at a price that was lower than the price of the chipset alone. Many early chip companies were reliant on sales of cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 6800
The 6800 ("''sixty-eight hundred''") is an 8-bit computing, 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the Motorola 6800 family, M6800 Microcomputer System (latter dubbed ''68xx'') that also included serial and parallel interface integrated circuit, ICs, RAM, read-only memory, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year. "Motorola's M6800 microcomputer system, which can operate from a single 5-volt supply, is moving out of the sampling stage and into full production." The small-quantity price of the MC6800 is . The MC6820 PIA cost . The 6800 has a 16-bit address bus that can directly access of memory and an 8-bit bi-directional data bus. It has 72 ...

Net D
Net 10, net 15, net 30 and net 60 (often hyphenated "net-" and/or followed by "days", e.g., "net 10 days") are forms of trade credit which specify that the net amount (the total outstanding on the invoice) is expected to be paid in full by the buyer within 10, 15, 30 or 60 days of the date when the goods are dispatched or the service is completed. Net 30 or net 60 terms are often coupled with a credit for early payment. The word ''net'' in this sense means "total after all discounts". It originally derives from the Latin ''nitere'' (to shine) and ''nitidus'' (elegant, trim), and more recently from the French ''net'' (sharp, neat, clean). Examples * The notation "net 30" indicates that full payment is expected within 30 days. If a $1000 invoice has the terms "net 30", the buyer must pay the full $1000 within 30 days. * The notation "2% 10, net 30" indicates that a 2% discount can be taken by the buyer only if payment is received in full within 10 days of the date of the invoice, a ...

Apple 1 Advertisement Oct 1976
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, 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 size of the resulting tree, allowing for easier harvesting. There are more th ...

Tandy Corporation
Tandy Corporation was an American family-owned leather goods company based in Fort Worth, Texas, United States. Tandy Leather was founded in 1919 as a leather supply store. By the end of the 1950s, under the tutelage of then-CEO Charles Tandy, the company expanded into the hobby market, making leather moccasins and coin purses, making huge sales among Scouts, leading to a fast growth in sales. Entering the 1960s, aiming to broaden the company horizon, Charles Tandy acquired a number of craft retail companies, including RadioShack in 1963, then an almost bankrupt chain of electronics stores in Boston. In the 1980s, now led by John Roach as CEO, the corporation started to invest into the personal computer market, being one of the pioneers in the personal computer race, being lauded by the magazine ''Financial World'' as "the driving force at the front-running company in the red-hot personal computer race." In 2000, the Tandy Corporation name was dropped and the entity became t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
