"In measuring and evaluating performance of an automobile and driver combination it is necessary to record data from the vehicle and driver while both are in the field.
The University of Missouri - Rolla Transportation Research Program performs this type of evaluation. The present method of recording data in the field is with a large, bulky, and somewhat fragile strip chart recorder.
The digital recording interface described in this paper is designed to permit replacement of the strip chart recorder with an audio tape recorder. The interface will allow simultaneous recording of two analog channels which may be reproduced as required. The interface is accurate to within 1.6% of full scale and costs less than $150"--Abstract, page ii.
