True. Back in high school we had a PDP-11/40. A physics class meeting
in a nearby classroom fired up a Tesla coil and blew a chunk of our
memory. The chips had holes burned in them and were literally smoking.
On a related note, I have an electrostatic precipitator (air cleaner,
not an ion generator) at home. Every once in a while, it arcs 6000
volts across its plates. It used to crash an old Osborne-1 I had until
I ran an extra ground cable from the keyboard to the main unit. It has
never bothered my 3b1, though.
