In September 1983 Stevens Institute of Technology (SIT) began a program requiring every incoming student to own a Digital Equipment Corporation PC-350 microcomputer. Past computing experiences at SIT, impact of the program, software and hardware considerations, and computing experiences in chemistry are reviewed. (JN)

The Apple game port has two types of inputs: the paddle input and the button input. Scientific applications of these input-output units are discussed, examining analog inputs (potentiometers, thermistors, and photoresistors), single bit digital inputs, and single-bit outputs. (JN)

Suggests purchasing a digital multimer (DMM) with an IEEE-488 option to interface an instrument to a microcomputer, indicating that a DMM is well protected from overloads and is easy to connect. An example of its use in an experiment involving hydrolysis of tertiary butyl alcohol (with program listing) is given. (JN)
