I was relucatant to include this in the FAQ, because it seems silly 
to go to this kind of trouble to avoid buying a US$20 part. I finally 
did add a descrption of the procedure taken from an old FAQ near the 
end of the document in the "Odds and Ends" section, due to popular 
demand. 

I still don't think this is worth the trouble and inconvenience. I 
keep a couple of spare M48T02 chips on hand, and when one fails, I 
just pop in a new one.
