The Elektor Junior Computer was a simple 6502 based Microprocessor development board published in the 1980's in the Dutch, German and later French and British versions of Elektor/Electuur, in the form of a series of articles, and four books. The MOS Technology 6502 is an 8-bit Microprocessor that was designed by Chuck Peddle for MOS Technology in 1975 A Microprocessor Development Board is a printed circuit board containing a Microprocessor and the minimal support logic needed for an engineer to become acquainted with the microprocessor Elektor is a monthly magazine about all aspects of Electronics, first published as "Elektuur" in the Netherlands in 1960, and now published worldwide It was developed by the German engineer Loys Nachtmann. In fact the Junior Computer was a virtual clone of the KIM-1, only it did not use the special I/O+ROM chips (MCS6530) but rather an of the shelf 6522 VIA and a 2716 2K EPROM. The KIM-1, short for K eyboard I nput M onitor, was a small 6502 -based Microcomputer kit developed and produced by MOS The 6522 Versatile Interface Adapter (VIA was an Integrated circuit made by MOS Technology, as well as Second sources including Rockwell and An EPROM, or E rasable P rogrammable '''''R'''ead-'''O'''nly '''M'''emory'', is a type of memory chip that retains its It also had a differerent physical shape, as it used the Eurocard board, and a 31 pin-DIN connectors for I/O and a DIN 41612 connector for system expansion. Overview DIN 41612 is a DIN standard for electrical connectors that are widely used in rack based electrical systems It was delivered as a Electronic kit, or you could just buy the two Printed circuit board's (main board and Seven-segment display board) only, and add your own components. An electronic Kit is a package of Electrical components used to build an electronic device. A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces A seven-segment display (abbreviation " 7-seg (ment display" less commonly known as a seven-segment indicator, is a form of electronic Display device
As It was much lower in price than an original KIM, many more Junior computers (several thousands) were used in the Netherlands, Germany and France, than original KIM-1's.
Later extension boards were developed, and a BASIC interpreter was ported. Elector Expansion boards specifically for the junior were a VDU (video terminal) (the "elekterminal"), an EPROM and SRAM expansion board, an 16/64KB DRAM board and EPROM programmer board, and even a Floppy disk controller, as well as a dozen smaller boards for small improvements and interfaces etc. A computer terminal is an electronic or electromechanical hardware device that is used for entering data into and displaying data from a Computer or a Computing Static random access memory (SRAM is a type of Semiconductor memory where the word static indicates that unlike ''dynamic'' RAM (DRAM, it does not In field of Computer hardware, the term programmer, chip programmer or device programmer refers to a Hardware device that configures programmable A floppy disk controller (FDC is a special-purpose chip and associated circuitry that directs and controls reading from and writing to a computer's floppy disk drive
