Ah, that also explains why I haven't heard it before here in the US.  This
must be a UK term, because we use "ground" here instead of "earth".

According to your definition, "-VE" to describe inverted logic in this
context is actually a misuse of the term.  Whether you consider +5V a logic
one and 0V a logic zero or the other way around, both schemes still keep
their voltage positive with respect to ground (earth).  Is this true or is
it that outsiders will just never understand all the nuances of "+VE" and
"-VE" (kinda like the rules to cricket)?
