Report of an experiment in which a prototype hardware monitor based on a general-purpose minicomputer was used (1) to determine the validity of a simulation of RAND's Video Graphic System (VGS) and (2) to investigate that system's response to various types of loading. The simulation proved unable to project absolute performance accurately, but was adequate for doing sensitivity analyses and investigating specific interactions. The VGS, run on an IBM 1800, was monitored both in its normal state and during controlled tests, the latter proving more informative. The monitor was reliable except for initial problems with probes and amplifiers. Though it was less powerful than similar commercial products, it was useful and had the advantage of being relatively economical. 55 pp. Ref.
