after the Intel SDK-80. One is currently displayed at the Norwegian Museum of Science and Technology. When introduced it was sold for apx. $6.000 MYCRO-1 is a microcomputer system based on the microprocessor Intel 8080. Some models have an Z80 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
