I have an article by Richard Esposito that describes how to upgrade D, E 
anf F boards.  I can scan the article (3 pages). I don't have what it 
takes to create a pdf file, though.

I can send a direct e-mail to people who want a copy of it ( I think 
that Roger Taylor wanted it too).

Send me your email address to :  benoit.bleau (at) verizon dot net ,  
and I'll send jpeg scans of the article.
