[comp.sys.cbm] My 64's Quirks

tjlee@iastate.edu (Tom Lee) (03/27/91)

	My C-64 sometimes resets when I turn on the disk drive or the printer.
Will it explode anytime soon?  That is, does anybody know if this is a sign of
a greater problem, or if this is frying something inside my machine?

My computer does this also.  If I turn on the printer when the computer is
on sometimes the computer is reset.  The printer is a dasiy wheel cardco 
something or other.  Its done this ever since we got the printer.  It's no
problem as long as I remember to save before turning the printer on. :)

This is something that shouldn't happen, but does on some machines.  The
RESET line on your computer actually runs out the serial port to the
other devices on your system.  The idea is that when you reset your
computer, the disk drives and printers should reset also, and this is
what happens.  There is supposed to be a diode which will prevent the
disk drive from resetting the computer, but some 64's have a weak diode,
and it does not always prevent the reset signal from getting through.
So, some serial devices can actually reset your computer.
