ABSTRACT:
A system for determining the revision history of printed circuit boards within a computer system. The revision number of printed circuit boards within a computer system can be conveniently ascertained, and there is no need to turn off the computer system or remove the panel because visual inspection of the printed circuit boards is not required. The system includes a revision number setting unit mounted on each printed circuit board for setting revision number data in each circuit board. The revision number and corresponding revision history is displayed in response to a command input from a keyboard. A processor reads revision number data from a selected printed circuit board in the computer system and provides it to a CRT.
