The Elektor Junior Computer was a simple 6502-based microprocessor development board published in the 1980s in the Dutch, German and later French, Spanish, British and Indian versions of Elektor/Elektuur, in the form of a series of articles, and four books. It was developed by the German engineer Loys Nachtmann.
The Junior Computer was a virtual clone of the
Eurocard board, and a 31-pin DIN connector for I/O and a DIN 41612 connector for system expansion. It was delivered as an electronic kit, or could purchased as two printed circuit boards (main board and Seven-segment display
board) only, for components to be installed.
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-1s.
Later extension boards were developed, and a BASIC interpreter was ported. Elektor expansion boards specifically for the Junior were an I/O interface card (including a
floppy disk controller
, as well as a dozen smaller boards for small improvements and interfaces.
