> I tried "virtual" shorts once but they were too drafty ; )

In the 80's I used to work in the service dept. of a traffic equipment
maker.  We had to repair new equipment that had plenty of "real" shorts
caused by faulty etching of PCBs (electrical test? - we didn't need no
stinkin' electrical test).  Sometimes the copper short was so small you
could not see it.  So we would charge up a big capacitor with < 5V and use
the stored energy to evaporate the copper short.  This technique was
referred to as "blow out your shorts".  8^)

Yes, it did work (most of the time).  As long as we didn't reverse bias the
chips...
