He's right - unless you're careful, and don't ground reset for too long,
you might have problems. I've destroyed my C64 too many times. I'm not
sure why, but one of the chips in there doesn't like being reseted for
more than 1/2 sec or so.
Also, another warning - don't plug or unplug your disc drive or printer
without switching the power off first. If your C64 is like mine, the
drive and the computer do NOT have a common ground. Well, they do, but
it is made through the drive cable. If the ground disconnects before the
signal, you might end up with 20V or more on the signal pin (there is no
reason for both machines to be at the same potential)
Just a couple of things I've learnt the hard way.
