Versatile Laboratory Aid
The Versatile Laboratory Aid (VELA) is a 4-channel Data logger, data logging tool that was created as part of a joint venture by Ashley Clarke, Keith Jones and David Binney of Leeds University and Educational Electronics. The VELA was designed to be used as a stand-alone data logger that could be used out in the field and it could then be taken back to the laboratory where it could be connected to a chart printer, oscilloscope or microcomputer for data analysis purposes. The VELA was designed and built with the intention that it would be used in schools and Universities to monitor Physics and Chemistry experiments as it could be attached to all manner or analogue probes and sensors such as pH meters, Thermometer, temperature sensors, light gates, Signal generator and microphones. Each of the VELA's four channels can be independently set to record voltages in the ranges of +/–250mV, +/–2.5V and +/–25V allowing a range of different input devices to be connected simultaneously. ...

Signal Generator
A signal generator is one of a class of Electronics, electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well. There are many different types of signal generators with different purposes and applications and at varying levels of expense. These types include function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators, and frequency generators. In general, no device is suitable for all possible applications. A signal generator may be as simple as an oscillator with calibrated frequency and amplitude. More general-purpose signal generators allow control of all the characteristics of a signal. Modern general-purpose signal generato ...

IBM-PC Compatible
An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. "Wintel" is a similar description that is more commonly used for modern computers. The designation "PC", as used in much of personal computer history, has not meant "personal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Machines 380Z
The Research Machines 380Z (often called the RML 380Z or RM 380Z) was an early 8-bit microcomputer produced by Research Machines in Oxford, England, from 1977 to 1985. Description The 380Z used a Z80 microprocessor (hence the name) with up to 56 KB of user RAM. When fitted with an optional floppy disk drive the system ran the CP/M operating system. The basic system came with a text-only monochrome video card, which could be enhanced with a 320×192 high-resolution graphics board. Aided by a British government subsidy to schools for half of the price the 380Z was sold mainly to educational institutions in the United Kingdom, with some also sold to industry. In 1979 a dual 8-inch disk system with 56 KB of memory cost £3266, and a 16 KB cassette-based system cost £965 (excluding VAT). Hardware Architecture The 380Z was packaged in a large, black, 19-inch rack-mount, rectangular metal case containing the power supply, a number of printed circuit boards and t ...

Commodore 64
The Commodore 64, also known as the C64, is an 8-bit computing, 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas). It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the VIC-20 and Commodore PET, the C64 took its name from its of RAM. With support for multicolor sprite (computer graphics), sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware. The C64 dominated the low-end computer market (except in the UK, France and Japan, lasting only about six months in Japan) for most of the later years of the 1980s. For a substantial period (1983–1986), the C64 had betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commodore PET
The Commodore PET is a line of personal computers produced starting in 1977 by Commodore International. A single all-in-one case combines a MOS Technology 6502 microprocessor, Commodore BASIC in read-only memory, keyboard, monochrome monitor, and, in early models, a cassette deck. Development of the system began in 1976, and it was demonstrated and sold as the first personal computer for the masses at the January 1977 Consumer Electronics Show. The name "PET" was suggested by Andre Souson after he saw the Pet Rock in Los Gatos, and stated they were going to make the "pet computer". It was backronymed to Personal Electronic Transactor. In a 1995 retrospective, ''Byte'' magazine—and subsequently many others—referred to the PET, Apple II and TRS-80 collectively as the "1977 trinity" of pioneering personal computers. Following the initial PET 2001, the design was updated through a series of models with more memory, better keyboard, larger screen, and other modifications. ...

BBC Micro
The BBC Microcomputer System, or BBC Micro, is a family of microcomputers developed and manufactured by Acorn Computers in the early 1980s as part of the BBC's Computer Literacy Project. Launched in December 1981, it was showcased across several educational BBC television programmes, such as ''The Computer Programme'' (1982), ''Making the Most of the Micro'' and ''Computers in Control'' (both 1983), and ''Micro Live'' (1985). Created in response to the BBC's call for bids for a microcomputer to complement its broadcasts and printed material, Acorn secured the contract with its rapidly prototyped “Proton” system, which was subsequently renamed the BBC Micro. Although it was announced towards the end of 1981, production issues initially delayed the fulfilment of many orders, causing deliveries to spill over into 1982. Nicknamed the “Beeb”, it soon became a fixture in British schools, advancing the BBC’s goal of improving computer literacy. Renowned for its strong build q ...

Department Of Trade And Industry (United Kingdom)
The Department of Trade and Industry (DTI) was a United Kingdom government department formed on 19 October 1970. It was replaced with the creation of the Department for Business, Enterprise and Regulatory Reform and the Department for Innovation, Universities and Skills on 28 June 2007. History The department was formed on 19 October 1970 through the merger of the Board of Trade and the Ministry of Technology, creating a new cabinet post of Secretary of State for Trade and Industry. Additionally, the department also took over the Department of Employment's former responsibilities for monopolies and mergers. However, in January 1974, the department's responsibilities for energy production were transferred to a newly created Department of Energy.
