Corvette (computer)

Corvette (Russian: Корвет) was an 8-bit personal computer in the USSR, created for Soviet schools in 1980s. The first device was a homemade computer, created in 1985 by employees of the Moscow State University for their purposes (physics experiments). The first description was made in the magazine «Microprocessor tools and systems».[1] The PC was named "ПК 8001" (21.08.1985).

Educational computer technology complex

"НИИСчётмаш" created an educational computer technology complex based on "Corvette"[2] It includes a teacher's computer (ПК8020, with FDD , a printer port) and about 15 computers for students (ПК8010), connected to the local network (19,5 kbit/s).

Variants

It has been mass-produced since 1987 year at the plants of the Ministry of Radio Technology (Soviet Union):[3]

Production

Even though this PC was created in a fairly short time, and the decision to produce a new computer was approved by the Council of Ministers, the start of the mass production was delayed.[6][7] Although the computer consisted exclusively of components already mastered by Soviet industry, it was not possible to increase production volumes on time, and the supplied components were of very poor quality. In addition, there was a competition with another computer of the same purpose.: UKNC. As a result, deliveries of the new computer were far behind the plan.:[6][8][9]

After the collapse of the USSR, the production of Corvettes was completed, incomplete cases were used to assemble numerous ZX Spectrum clones. "LINTech" ("Laboratory of Information Technologies") carried out the modernization of the "Corvette" - the network was modernized and an IBM PC-compatible computer was installed as the head machine. Network speed increased from 19.5 kilobits / sec to 375 kilobits / sec. This revision was recommended by the Ministry of Education of the Russian Federation for use in schools.[10]
