Abstract
A circuit is described for interfacing response keys and other discrete inputs from psychological apparatus to a computer. Some of the unique features are: high noise immunity, the ability to transmit data over long distances, and electrical protection of the computer from accidental and potentially catastrophic high voltage inputs.
