Voice Board Revisions: Rhodes (trace cut)

By David Clarke [21030085++] <ac151@ncf.ca>

I have seen at least 4 physically different printed circuit boards with this same layout, and the same trace-cut and strap. The latter 3 of these have fabrication dates on the PCB itself, the 2nd being 21-82, the 4th being 25-82.
