Or there were the old scopes where you used patch cords and banana jacks. We had what was left of the power cord for one such scope hanging in the front of the motors lab in college that showed the importance of having your setup checked before applying power. Seems the hot and ground leads to the scope >from the motor being measured got reversed and the 120 VAC supply was bypassed to ground through the green wire in the power cord. For a short period of time. Then the green wire acted as a fuse. That cord was NOT repairable. And, NO, I was not the culprit. Didn't happen on my watch.
