This article describes the development of an automated microprocessorhyphen;based datahyphen;acquisition system and, in particular, the use of an inexpensive microcomputer to automate an acoustic experiment. Specifically, it explains the use of a Motorola MC6801 in the singlehyphen;chip mode to control a rather complex experimental process. The system is configured to provide for automated, twohyphen;dimensional data acquisition of ultrasonic transmissibility through a specimen surface. Results to evaluate the accuracy and the performance of the system with known analytical predictions will be presented.
