Apple IIe
The Apple IIe (styled as Apple //e) is the third model in the Apple II series of personal computers produced by Apple Inc., Apple Computer. It was released in January 1983 as the successor to the Apple II Plus. The ''e'' in the name stands for ''enhanced''. It is the first Apple II with built-in lowercase, 80-column text support and 64K RAM standard, while reducing the total chip count from previous models by approximately 75%. Improved expandability combined with the new features made for an attractive general-purpose machine to first-time computer shoppers. As the last surviving model of the Apple II computer line before discontinuation, and having been manufactured and sold for nearly 11 years with relatively few changes, the IIe was the longest-lived computer in Apple's history. History Apple Inc., Apple Computer planned to discontinue the Apple II series after the introduction of the Apple III in 1980; the company intended to clearly establish market segmentation by desig ...

Apple 80-Column Text Card
The Apple 80-Column Text Card is an expansion card for the Apple IIe computer to give it the option of displaying 80 columns of text instead of 40 columns. Two models were available; the cheaper 80-column card has just enough extra random-access memory, RAM to double the video memory capacity, and the Extended 80-Column Text Card has an additional 64 kilobytes of RAM, bringing the computer's total RAM to 128 KB. VisiCalc and Disk II made the Apple II very popular in small businesses, which asked the company for 80-column support, but Apple delayed improving the Apple II because for three years it expected that the unsuccessful Apple III would be the company's business computer. The 80-column cards were the alternative. The cards go in the IIe's Auxiliary Slot, which exists in addition to the seven standard Apple II peripheral cards, Apple II peripheral slots present on all expandable Apple II series machines. Although in a separate slot, the card is closely associated with slot #3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WDC 65C02
The Western Design Center (WDC) 65C02 microprocessor is an enhanced CMOS version of the popular nMOS-based 8-bit MOS Technology 6502. It uses less power than the original 6502, fixes several problems, and adds new instructions and addressing modes. The power usage is on the order of 10 to 20 times less than the original 6502 running at the same speed; its reduced power consumption has made it useful in portable computer roles and industrial microcontroller systems. The 65C02 has also been used in some home computers, as well as in embedded applications, including implanted medical devices. Development of the WDC 65C02 began in 1981 with samples released in early 1983. The 65C02 was officially released sometime shortly after. WDC licensed the design to Synertek, NCR, GTE Microcircuits, and Rockwell Semiconductor. Rockwell's primary interest was in the embedded market and asked for several new commands to be added to aid in this role. These were later copied back into the b ...

Apple Lisa
Lisa is a desktop computer developed by Apple, produced from January 19, 1983, to August 1, 1986, and succeeded by Macintosh. It is generally considered the first mass-market personal computer operable through a graphical user interface (GUI). In 1983, a machine like the Lisa was still so expensive that it was primarily marketed to individual and small and medium-sized businesses as a groundbreaking new alternative to much bigger and more expensive mainframes or minicomputers such as from IBM, that either require additional, expensive consultancy from the supplier, hiring specially trained personnel, or at least, a much steeper learning curve to maintain and operate. Development of project "LISA" began in 1978. It underwent many changes and shipped at with a five-megabyte hard drive. It was affected by its high price, insufficient software, unreliable FileWare (codename Twiggy) floppy disks, and the imminent release of the cheaper and faster Macintosh. Only 60,000 Lisa units we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Segmentation
In marketing, market segmentation or customer segmentation is the process of dividing a consumer or business market into meaningful sub-groups of current or potential customers (or consumers) known as ''segments''. Its purpose is to identify profitable and growing segments that a company can target with distinct marketing strategies. In dividing or segmenting markets, researchers typically look for common characteristics such as shared needs, common interests, similar lifestyles, or even similar demographic profiles. The overall aim of segmentation is to identify ''high-yield segments'' – that is, those segments that are likely to be the most profitable or that have growth potential – so that these can be selected for special attention (i.e. become target markets). Many different ways to segment a market have been identified. Business-to-business (B2B) sellers might segment the market into different types of businesses or countries, while business-to-consumer (B2C) seller ...

Large Scale Integration
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using disc ...
