Micro-80
The Micro-80 () was the first do-it-yourself home computer in the Soviet Union. Overview Schematics and information were published in the local DIY electronic magazine ''Radio'' in 1983. It was complex, using an KR580VM80A-based system (a clone of the Intel 8080 The Intel 8080 is Intel's second 8-bit computing, 8-bit microprocessor. Introduced in April 1974, the 8080 was an enhanced successor to the earlier Intel 8008 microprocessor, although without binary compatibility.'' Electronic News'' was a week ...) which contained about 200 ICs. This system gained low popularity, but set a precedent in getting the attention of hobbyists for DIY computers, and later other DIY computers were published by ''Radio'' and other DIY magazines.Сергей Попов (2011).

Radio-86RK
The Radio-86RK () is a build-it-yourself home computer designed in the Soviet Union. It was featured in the popular ''Radio'' () magazine for radio hams and electronics hobbyists in 1986. The letters RK in the title stands for the words ''Radio ham's Computer'' (). Design of the computer was published in a series of articles describing its logical structure, electrical circuitry, drawings of printed circuit boards and firmware. The computer could be built entirely out of standard off-the-shelf parts. Later it was also available in a kit form as well as fully assembled form. Predecessors The Radio-86RK is the successor of earlier build-it-yourself computer of the same designers, the Micro-80, and has limited compatibility with it. Its description was also published in a series of articles in the ''Radio'' magazine in the early 1980s. But its complex design, consisting of several modules and containing about 200 chips, lack of printed circuit board drawings and most importantly ...

KR580VM80A
The KR580VM80A () is a Soviet microprocessor, a clone (computer science), clone of the Intel Intel 8080, 8080 CPU. Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM EVM, SM1800 computer in 1979. Initially called the K580IK80 (К580ИК80), it was produced in a 48-pin planar process, planar metal-ceramic package. Later, a version in a Dual in-line package, PDIP-40 package was produced and was named the KR580IK80A (КР580ИК80А). The pin layout of the latter completely matched that of Intel's Intel 8080, 8080A CPU. In 1986 this CPU received a new part number to conform with the 1980 Soviet integrated circuit designation and became known as the KR580VM80A (КР580ВМ80А), the number it is most widely known by today (the KR580VV51A and KR580VV55A peripheral devices went through similar revisions). Normal clock frequency for the K580IK80A is 2 MHz, with speeds up to 2.5 MHz for the KR580VM80A. The KR580IK8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
