MYCRO-1 explained

The MYCRO-1 was a microcomputer manufactured and sold by Mycron of Oslo, Norway. Built around the Intel 8080^[1] CPU, it was one of the first commercial single-board computer after the Intel SDK-80. One is currently displayed at the Norwegian Museum of Science and Technology.^[2]

When introduced, it was sold for approximately $6.000

MYCRO-1 is a microcomputer system based on the microprocessor Intel 8080. Some models have a Zilog Z80^[3] CPU. Since the Z80 is backward compatible with the 8080, this was probably a cost reduction measure. The MYCRO-1 system was designed by MYCRON Data Industri as an entry In the market place for higher powered microcomputer systems.

A typical basic configuration of the system:

DIM-1001 CPU
DIM-1013 16K-byte dynamic RAM
DIM-1090 Chassis with motherboard
DIM-1091 Power supply with switch panel
