You may find a BSP that will have some major change, but, most of the issue changes were Western Electric modifications for component changes due to manufacturing run changes. For example, a resistor may have been 20% tolerance and the new run is now 10% tolerance. That goes for capacitors and relays as well. Some, and these would have a BSP associated with it, were major changes in reliability and/or feature changes. If the revision affected the installation or operation of the card, and a tech needed to know what the revision was designed to do, then a BSP was issued.
The G and H revs were answers to ITT and others providing MOH function.
