Tano (computer)
The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., initially in Swansea, Wales before moving to Port Talbot, Wales (until 1984) and by Eurohard S.A. in Casar de Cáceres, Spain (from 1984 to 1987), and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively. Product history Dragon Data entered the market in August 1982 with the Dragon 32. The Dragon 64 followed a year later. The computers sold well initially and attracted the interest of independent software developers including Microdeal. A companion magazine, ''Dragon User'', began publication shortly after the microcomputer's launch. Despite this initial success, there were two technical impediments to the Dragon's acceptance.

Casar De Cáceres
Casar de Cáceres is a town and municipality in the province of Province of Cáceres, Cáceres, in the autonomous community of Extremadura. With 4532 inhabitants in 2017, it is the second most populous municipality in the Tajo-Salor Mancomunidad. In the municipality there are two population centers: Casar de Cáceres and La Perala. The capital of the municipality is located about 10 kilometers from the capital of Caceres, in the middle of Vía de la Plata. During the Ancien Régime, the municipality belonged to the c''omunidad de villa y tierra'' of Cáceres. and until the first half of the 19th century it was considered as a hamlet of the village of Cáceres. History Although the precise origin of the town is unknown, archaeologists have found a Bronze Age fort, a pre-Roman funeral stele and anthropomorphic tombs, among other remains, suggesting inhabitants since ancient times. During Roman times, the town lay along the Vía de la Plata. In 1291, Sancho IV of Castile granted th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megahertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or Cycle per second, cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in metric prefix, multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the photon energy, energy of a photon, via the Planck relation ''E'' = ''hν'', ...

Motorola 6809
The Motorola 6809 ("''sixty-eight-oh-nine''") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes. Among the most powerful 8-bit processors of its era, it was also much more expensive. In 1980 a 6809 in single-unit quantities was compared to for a Zilog Z80 and for a 6502. It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature competitiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
