An approach to the collection and manipulation of time-based data using the IBM PC and BASICA

With the advent of increasingly integrated, powerful and inexpensivedigital electronics, relatively powerful computers have becomeavailable to the general public. Along with this technologicalboom there has been a concomitant increase in the availabilityof over-the-counter software packages which can be used by researchscientists for program development. In the past, the developmentof computer programs for the collection of large amounts oftime-based data was expensive and time consuming; however, theintroduction of the current generation of 16-bit microcomputersand associated hardware and software packages has enabled investigatorswith only a rudimentary knowledge of computers and interfacingto begin to design programs. The schemes and algorithms, developedusing BASICA on an IBM-Personal Computer, which are describedin this article can serve other investigators as models forthe assembly of their own programs for the collection, manipulationand plotting of time-based data. The incorporation of inexpensivecomputer graphics hardware and software, which provided a simplesolution to the problem of analysis and presentation of largeamounts of data, will also be discussed.
