On my XT, whenever I used to plug the com port in, I'd often
get a spark, once the serial port was stuffed because of that
and needed repair.  I never learnt my lesson, but I've never
had a problem since, on my more modern machines.  Did they
improve that technology or something?  The XT was a Commodore
PC5.  BFN.  Paul.
