Is that right? OR does the automatic discharge of the crt only happen on the SE line??

I worked on LOT'S of the 128, 512, Plus models in college, and we ALWAYS screwdriver discharged them and they ALWAYS snapped the static charge off. YES, we did it wrong We didn't slow discharge through a big resistor and screwdriver lead.... But I can attest there WAS a charge there and some of those machines were off for many days before we cracked the cases on them.

Curious for sure to the answer here.
