       And a good thing, too. The FCC has done a good job in this area.
Remember when a TRS-80 model I and a Milton Bradley Big Trak toy would
crash each other if brought within a few feet?  In the late '70s, there was
real fear that a big chunk of the electromagnetic spectrum would be
completely unusable for radio in urban areas.  Tight standards by
the FCC and the comparable German and Japanese authorities avoided this
fate, and now you can fill offices up with electronic equipment without
worrying about electromagnetic compatibility.

       Think of the alternative: long lists in the computer magazines of
what interferes with what, running around offices with field strength
meters trying to find out what's knocking what off the air, inability to
use a computer and a TV in the same apartment building, landlords 
prohibiting computer use...
