If I've got to the point where I need to hit RESET, it doesn't matter.
It doesn't matter to the software, but there's the risk of shorting things
together that don't want to be shorted.
The old
PETs don't AFAIK have the internal expansion connector - they have
an edge connector sticking out at one side. Very useful for toggling
RESET with a pair of tweezers!
Don't miss! Occasionally I corrupted I/O registers and disabled
the interrupts that
serviced the keyboard. You'd better not miss when toggling IRQ with the
tweezers!
I used to reset my development C-64 with a paperclip that I bent into a
hair-pin shape with a .3" or .4" spacing to fit the proper pins on the
expansion connector. I even melted a drinking straw and wrapped it around
the top of the loop for a "handle". It was my programmer's reset for
years.
