Juku E5101 was a personal computer targeted at Estonian schools which was released in 1988. The computer had monochrome display, a mouse and basic LAN capabilities, it ran CP/M 2.2 based EKDOS and had a Soviet Intel 8080A clone KR580VM80A for CPU. [1] [2]
Juku E5101 was developed by Special Construction Bureau of Computing Technology "EKTA" and the Institute of Cybernetics of the Academy of Sciences of Estonia, test batch of 100 was produced in cooperation with Estron factory in 1986. The computer initially used tape recorder as storage and was reported as first computer in USSR to have mouse attached. In a multibus (Soviet I41) compatible expansion slot one could also connect 32 KiB memory expansion cards or ROM cartridges.
Juku E5104 production of which started in December 1988 was upgraded to use dual 5.25 inch diskette drive and drivers for printers. Despite relabelling it to "intellectual terminal for real-time system E5104", the label presented on main unit remained E5101.
During first two years of serial production around 2000 Jukus were produced and last batch of 500 was ordered by Estonian Ministry of Education in 1992. Altogether 3000 Jukus were produced at Narva, Baltijets plant (from Russian "Балтиец", Baltiyets), 2500 of them for school use. [3]
In 1991 many, if not all, bigger (at least 100 pupils) Estonian schools had a computer classroom that was furnished with those machines and Epson LX800 printers.
Although the production was delayed four years and computers delivered were technologically outdated, Jukus did enable Estonia to "gain a head start in mass school computerization" by providing early access to computers and a standardized study environment. Despite conceived lack of end user skills and the shortage of computer professionals, there were schools having dedicated teachers and students themselves writing software for Jukus during extra hours at computer class, often convincing schools to lend computers home for summer vacation. [4]
In general tens of thousands students got their first computing experience with Juku "much more, much earlier and more frequently than would have been possible otherwise". [4]
Atari ST is a line of personal computers from Atari Corporation and the successor to the company's 8-bit home computers. The initial model, the Atari 520ST, had limited release in April–June 1985, and was widely available in July. It was the first personal computer with a bitmapped color graphical user interface, using a version of Digital Research's GEM interface / operating system from February 1985. The Atari 1040ST, released in 1986 with 1 MB of memory, was the first home computer with a cost per kilobyte of RAM under US$1/KB.
The Xerox Alto is a computer system developed at Xerox PARC in the 1970s. It is considered one of the first workstations or personal computers, and its development pioneered many aspects of modern computing. It features a graphical user interface (GUI), a mouse, Ethernet networking, and the ability to run multiple applications simultaneously. It is one of the first computers to use a WYSIWYG text editor and has a bit-mapped display. The Alto did not succeed commercially, but it had a significant influence on the development of future computer systems.
The Apple IIGS is a 16-bit personal computer produced by Apple Computer. It is the fifth and most powerful of the Apple II family. It is compatible with earlier Apple II models, but has a Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST. The "GS" in the name stands for "Graphics and Sound", referring to its enhanced multimedia hardware, especially its state-of-the-art audio.
The ImageWriter is a product line of dot matrix printers formerly manufactured by Apple Computer, Inc., and designed then to be compatible with their entire line of computers. There were three different models introduced over time, which were popular among Apple II and Mac owners.
Project Athena was a joint project of MIT, Digital Equipment Corporation, and IBM to produce a campus-wide distributed computing environment for educational use. It was launched in 1983, and research and development ran until June 30, 1991. As of 2023, Athena is still in production use at MIT. It works as software that makes a machine a thin client, that will download educational applications from the MIT servers on demand.
BESM-6 was a Soviet electronic computer of the BESM series.
Olivetti S.p.A. is an Italian manufacturer of computers, tablets, smartphones, printers and other such business products as calculators and fax machines. Headquartered in Ivrea, in the Metropolitan City of Turin, the company has been part of TIM Group since 2003.
The Commodore 64 home computer used various external peripherals. Due to the backwards compatibility of the Commodore 128, most peripherals would also work on that system. There is also some compatibility with the VIC-20 and Commodore PET.
Cinema of Estonia is the film industry of the Republic of Estonia. The motion pictures have won international awards and each year new Estonian films are seen at film festivals around the globe.
The Agat was a series of 8-bit computers produced in the Soviet Union. It used the same MOS Technology 6502 microprocessor as Apple II and BBC Micro, amongst many others. Commissioned by the USSR Ministry of Radio, for many years it was a popular microcomputer in Soviet schools.
Ural is a series of mainframe computers built in the former Soviet Union.
Tiigrihüpe was a project undertaken by the Republic of Estonia to heavily invest in development and expansion of computer and network infrastructure in Estonia, with a particular emphasis on education. The project was first proposed in 1996 by Toomas Hendrik Ilves, then ambassador of Estonia to United States and later President of Estonia, and Jaak Aaviksoo, then minister of Education. The project was announced by Lennart Meri, the President of Estonia, on 21 February 1996. Funds for the foundation of Tiigrihüpe were first allocated in national budget of 1997.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
DAC-1, for Design Augmented by Computer, was one of the earliest graphical computer aided design systems. Developed by General Motors, IBM was brought in as a partner in 1960 and the two developed the system and released it to production in 1963. It was publicly unveiled at the Fall Joint Computer Conference in Detroit 1964. GM used the DAC system, continually modified, into the 1970s when it was succeeded by CADANCE.
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
The history of computing in the Soviet Union began in the late 1940s, when the country began to develop its Small Electronic Calculating Machine (MESM) at the Kiev Institute of Electrotechnology in Feofaniya. Initial ideological opposition to cybernetics in the Soviet Union was overcome by a Khrushchev era policy that encouraged computer production.
Poisk is an IBM-compatible computer built by KPO Electronmash in Kyiv, Ukrainian SSR during the Soviet era. It is based on the K1810VM88 microprocessor, a clone of the Intel 8088. Developed since 1987 and released in 1989, it was the most common IBM-compatible computer in the Soviet Union.
