Why does everyone assume this guy is a bozo who's running
cable off a thinnet T? I figured he was talking about AUI
cables. Wouldn't WD have told him about his error if he
was running cables off a thinnet T, instead of admitting
_they_ had a problem?

The AUI spec is 50 meters so 125 feet should be legal if
he is talking about AUI cables.
