The Rockwell AIM 65 is recommended for use in physics laboratories. Among advantages cited are that the basic board can be purchased customized; for example, it can be purchased with or without a printer, power supply, extra memory, and other items. In addition, the computer is basically designed to control equipment and take data from peripheral equipment. Programming the AIM 65 for experimental work involves using BASIC and assembly programming languages. Two program listings are included for use in a multiple photocell timing experiment. A flow chart illustrating the specific functions being handled by the assembly program and how computing can be done in either assembly or BASIC is also included. When done by careful students using the computer, the experiment takes 5 minutes. Without the computer, the same experiment takes 2 to 2.5 hours. In addition, without computer control, data collection is slow and cumbersome and errors may range from 7 to 20 percent or higher. Use of the computer for data collection is recommended for advanced students who have had two or three laboratory courses. (JN)
