|                          Part revisions are tracked according to DEC Standard 012 conventions.                               |

|                          and can replace earlier revisions - a "C1" can replace an "A1" and a "B1";                          |
|                          if the numeric only changes, the new part is interchangeable and backwards                          |
|                          compatible - D1, D2, and D3 are interchangeable and can replace earlier                             |
