The El Graphix kit added the ability to display lower case characters and "chunky" graphics. The Printer Interface was an S-100 Bus card giving the Super-80 a Centronics parallel printer port. [6] The VDU Expansion Board (VDUEB) was an enhanced video display board for the Super-80 developed by Microcomputer Engineering (MCE). The VDUEB gave the ...

Sold as the "MCS-8 Micro Computer Set". [4] [5] MOS Technology KIM-1: MOS Technology 6502: 1975: complete board: MOS's developer kit for the 6502, widely used in a number ...
It was a small machine built on two Eurocard-standard circuit boards and it could be purchased ready-built or in kit form. one card (shown right) with the I/O part of the computer: a LED seven segment display, a 25-key keypad (hex+function keys), and a cassette CUTS interface (the circuitry to the left of the keypad)
The editorial board published an appeal to the Soviet electronics industry, proposing they begin producing Radio-86RK kits commercially. [11] By the end of the 1980s manufacturing of computer cases, keyboards and main boards for the Radio-86RK, as well as selling electronic components were carried out by numerous cooperatives.
The most important feature of the microprocessor development board was the ROM-based built-in machine language monitor, or "debugger" as it was also sometimes called.. Often the name of the board was related to the name of this monitor program, for example the name of the monitor program of the KIM-1 was "Keyboard Input Monitor", because the ROM-based software allowed entry of programs without ...
The Pixie required a 1.76 MHz clock, and since that was an uncommon crystal frequency, usually a readily available 3.579545 MHz colorburst crystal was instead used in a separate oscillator circuit with a divide-by-two circuit to drive the clock inputs of both the microprocessor and Pixie. The resulting 1.7897725 MHz clock was close enough for ...
