History Speccy - ZX-Spectrum - past and present.
D-Man ZX-Spectrum: Past and Present. ---------------------------------- Machine type ZX were developed by Clive Sinclair and produced by Sinclair Research Ltd., he created the same. In the beginning was the ZX-80, then the ZX-81. By today's standards characteristics of these machines can only evoke a smile: black and white screen RAM ob'emom 1KB (!), Expandable to 16KB. But for early 80's it was a real discovery. In 1981. "For the great services in the computerization of the country, "Sinclair was granted title of nobility. Computer ZX-SPECTRUM was established in 1982. His heart was an 8-bit Z-80 processor running at 3.5Mgts, produced by "Zilog". By the way, this processor is still produced in many countries, including Russia. By its characteristics, it still satisfies the developers automation devices, and while the Z-80 superior products r. "Intel", and was the basis for many PCs. First ZX-Spectrum (hereinafter Speccy) had a 16K ROM. (Which significantly expanded the capabilities embedded operating system) color screen resolution 256x192 with an opportunity to paint each block of 8x8 pixels in 2 colors from a palette of 8 colors with two gradations of brightness (Total 16 colors); ob'emom 48Kb RAM. All ZX could be used as a monitor, a regular household TV, and instead of any non-volatile memory devices - cassette player. Such is possible now. On average, capacity of one tape is about 0.5Mb in standard recording density, that quite a lot compared to the size RAM and the size of programs. These opportunities helped to become Speccy one of the most popular home computers. At the end of 1985. was released ZX-Spectrum 128, with an extended until 128Kb. RAM, 32KB ROM, two pages and three-channel videoOZU sound processor, and thus was fully compatible with (!!!) previous machines. This option is a computer with a floppy drive under control TR-DOS is now the most popular, although There are many users of 48-x machines. After 1986. r. "Sinclair Research" failed to Project Sinclair QL. It was conceived as a cheaper alternative IBM PC and had a high performance: memory - 128KB of expandable to 4MB, a powerful 32-bit processor, operating at 7MHz., good graphics and sound. By the concept and power of this model preceded by at least 3 years so popular in the West Commodore Amiga and Atari ST (not to mention much of the IBM PC, which is trying to become a home machine, we now). At the beginning of 1988 saw the publication of the last car in the west Series "ZX". It was a Z88, one of the first laptops (may be first). Data on it is incomplete: the Z88 processor was Z80H, operating at 7MHz with reduced power consumption; Liquid Crystal Display (with graphics). Z88 could be applied wherever needed a computer at hand. " In the 80 years, "SPECTRUM" was considered the best 8-bit home computer, despite the presence of competitors (with the same Z-80) as the SAM CUPE, YAMAHA MSX, ENTERPRISE, and others. Around 1988 Speccy stepped over the boundary of the USSR and began to conquer the hearts nepugannyh users and the mind poor industry, which quickly adjusted release compatible machines. Cost of them was about 60-80 rubles, and sold in the store they average 1500 rubles. because home PC was a luxury. Do not doze and amateurs: the scheme Speccy could be repeated literally at the knee, reworked based on the availability kompektuyuschih (all chips produced in USSR, including the processor). At the moment of greatest success in the market for West a week before the sold out 15,000 cars in Russia, 100-200 machines took in 1 day (and the second did not exist). In 1991 r. "Inforkom" magazine has launched "ZX-Revue", and a lot of other literature, users need. Unification of the former amateur production compatible with the ZX-Spectrum machines are gradually formed firms, developers, who began to develop a platform in the direction of improve the performance and quality of machines, standardizing their parameters. This is a long and arduous process was completed by 1995. The most massive counterparts Speccy have: two or more video mode; can run on CP / M; CPU clock 3.5-7MHz. (Individual copies to 21Mgts), up to 512K ROM, RAM, up to 2MB (some up to 4 MB), a standard 3-channel music processor, and music expansion card, mouse. The most evolved machines allow you to work with the hard drive up to 3.2 GB, connect an older SIMM memory cards and ISA, have built-in modem ... Most often, Speccy connect a printer, programmer, homemade or factory modem, but sometimes connect card image capture, homemade scanners, analog-digital converters, auxiliary Dendy (for storing programs disks, and resource use consoles for its programming). Currently, ZX-Spectrum - the only computer produced in Russia and exported abroad (in Poland, England, Germany). Parallel to the development of iron gradually grew and skill programmers, not least because that living on the Speccy, it is impossible not get at least some programming skills. Number software is huge, but it does not always meet today's needs, because there is both an opportunity and the need to write something of my own (on the PC it is impossible and not needed for various reasons). Most programs written directly in the language of the microprocessor, which allows you to explore interaction programs and hardware machines. By limiting simplicity and ease of construction of Iron Software Speccy is the ideal machine for training purposes. In addition, the most democratic computer: at cost price, he has no competitors. Thus, in 1993. from individuals and small teams began to form large groups of hackers, coders, artists, musicians, radio, dealers ... At the moment the largest groups of its employees have a 5-10 Russian cities, some groups are interstate. Many work not only on the Speccy, but on a different computer from him: Amiga, Mac, IBM, VAX / VMS, Alpha, BK-0010-01 ... Many people try to earn a living programming, development periphery, but Can not all (as elsewhere). Writing programs often associated with both time-consuming, and money. The author often risk get nothing for their work, or earn less than I could. Almost every user of the medium-high level can copy the program, copy-protected, and how Experience shows that protection can withstand only up to hit a stuffed with a hand of an experienced hacker. As a consequence, country walks a lot of free software that is both good and bad (though whom). In the last 2-3 years have emerged and operate networks based on ZX-Spectrum. They are organized active users free, works on the principles and statutes FIDOnet. Most major networks in Moscow and St. Petersburg. Network is rarely isolated from the outside world, often almost without interruption is a FIDO and INTERNET. There are also sites providing support to the Speccy INTERNET, and often, these pages belong hacker commands. Also, since 1996. in St. Petersburg, the festival komyuternogo arts and programs ENLIGHT, which come Active spektrumisty from all cities in Russia, CIS (and now and distant) countries to show their work, poobschatsya, "See those who are familiar with for a long time, and you see for the first time." In mandatory at the festival are the developers of iron, Leading programmers, and local correspondents tsetralnyh electronic publications are known hackers ... A similar event is planned this year in Moscow, under name FUNTOP'98. Last year in St. Petreburge present and active representatives of the public spektrumovkoy city of Voronezh. We hope to get to such an event more than once. -------------------------------------------------- -------------( C) Virtual Vision Group 1998.
