Abstract
Methods for collection of data from laboratory experiments have advanced rapidly over the past few years. Computers, large and small, have been used to acquire, process, and format experimental information presented from nearly all types of instrumentation. This paper deals with the use of connected multiple computers to optimize the power and economy of such a hierarchical system presently being implemented at the University of Oregon. Our implementation plan was divided into three stages. The procedure used was to acquire several small computers which are connected through suitable interfaces to chemical instrumentation, one message concentration, and a large time-sharing computer. Stage I was initiated in 1967, and we have just completed phase 3. The system has been used to collect and process data from several complex experiments. The results of these experiments, along with the experimental advantages and disadvantages of our approach will be discussed in the paper.
