Abstract

A Digital Data Acquisition System (DDAS) microcomputer was designed and constructed to interface between a six-channel analog seismograph and a digital cassette recorder. The DDAS microcomputer is a relatively inexpensive microcomputer built around the popular Z-80 microprocessor chip. It is portable and has 26K bytes of memory. It was designed to convert analog data in to digital with some processing performed before storing on the digital cassette recorder, for later analysis. The same hardware or circuitry of the DDAS microcomputer can perform other functions and work with other geophysical equipment by changing the software of the microcomputer.
