There is disclosed herein an apparatus for use in automated testing of elements in data processing systems such as the central processing unit. The system is comprised of a microprocessor with associated firmware, RAM and peripheral communications devices. There are two communication interface ports for receiving commands and instructions from local and remote computer terminals or from data processing units programmed to cause the testing apparatus to perform predetermined sequences of tests. There is also a port for connection to a portable maintenance panel which can be held in the hand of a field engineer for controlling the testing apparatus. The system is designed to replace prior art maintenance panels used for debugging computer hardware.
