Writing programs for the student psychology laboratory on the Apple II series of microcomputers presents the programmer with a number of problems. Among these are increasing program execution speed, obtaining precise response and interval timing, reducing program memory requirements, obtaining efficient disk I/O, providing good error trapping, and presenting clear screen displays. Since Applesoft BASIC is not equipped with many of the desirable features of a more advanced language, ways to solve these problems are not obvious. This paper suggests a number of potential solutions and provides additional sources of information.
