Case study of a microcomputer-minicomputer link

A microcomputer-minicomputer link, useful in the implementation of network configurations involving microcomputers and minicomputers, is described. The link, between a PDP-11 minicomputer and an 8080 microcomputer is over a serial line between the DZ11 module of the minicomputer and the UART interface of the microcomputer. The details of the essential hardware and software aspects of the link are presented.
