Gary,
 All computers are running at Radio Frequency and generate Radio Frequency 
Interferance. (RFI) When they say "'486-66" they're talking about the machine 
running at 66 mhz. TV freqencies start at 150 mhz or so (I don't have a 
frequency allocation chart handy), but the first harmonic of 66 is 132, so 
it's getting close.
Eliminating RFI is the subject of many books, but the basics consist of 
placing the emitter (the computer) inside of a METAL enclosure (metalized 
plastic counts) that is all connected together in one piece electrically, 
then grounded. That means that all the screws need to be in the cover, the 
extra expansion slots need to have covers, the expansion boards need to have 
screws installed, etc. If you return the machine to the configuration that 
you received it in, or as close as possible, you should be on the right 
track. Computer manufacturers spend LOTS of money to get these things 
certified with the FCC, and when you ignore the above points, you're sure to 
make the machine exceed allowable emissions.
Running a machine that exceeds allowable emissions makes you a bad neighbor 
and is justifiable only if you don't HAVE close neighbors.
