we liked to go on service calls in full dust-suits and respirators, with the (telephone line) tone-tracer live in our hands... get near any electronic device and it hummmmz nastily... under fluorescent lights it is truly scary... and tell the people in the office that there was nothing to be concerned about (while muttering urgently to each other and departing with great haste)
Tulane University was a happier place for our presence.
LOL -- man o man -- the good old days when technology was in the hands of us few wizards.
