Note that the schematic revision (CS) and the corresponding etch
revision often do not match. A particular etch can have different
levels of ECO corresponding to different schematic revisions, and a
particular schematic revision might correspond to both an older etch
with ECOs and a newer etc without ECOs (or with fewer ECOs). The
schematic revision is supposed to be stamped on the board or handle,
and updated if ECOs are applied in the field, but they're not always
The field maintenance print sets often, but not always, have a table
listing the correspondences.
