Please have a look at the message and the
discussions around that time (April 1999).  Do you have first-hand experience
of the "smoke poke" in action?

Remember, on the PET, the horizontal and vertical sync rates are fixed.
On the VDC (C128) or the TED (264 series), you could probably fry some
monitor or TV by modifying the timings.  My 14" Sony is still alive even
after some torturing with NTSC signals.  (It whistled a little but showed
a black&white picture.)
