Abstract
Apparatus for controlling the operational speed of a peripheral multispeed record/playback device so that the device and a connected computer can communicate at a compatible data rate. When a speed control operation is initiated, the device generates index pulses at a rapid rate. The computer generates a series of n test pulses in response to the generation of the first index pulse. The computer then times how long the n test pulses take to be generated. The peripheral device is then told to run at the data rate represented by how long it took to generate the n test pulses.
