Someone wrote a science-fiction book about it a decade or so ago. Nuclear weapon air bursts at strategic locations knocked out all unhardened defense and communication sites, rendering us suddenly deaf, dumb and blind and unable to operate our vehicles. Not to mention dead, too... I understand that gallium arsenide circuits are resistant to EMP rendering them inoperable; not so with conventional silicon. I wonder if the CPU in my Digilux 2 is made of gallium arsenide? :-) Len -- -----Original Message----- From: lug-bounces+ljkapner=cox.net@leica-users.org [mailto:lug-bounces+ljkapner=cox.net@leica-users.org] On Behalf Of Feli di Giorgio Sent: Friday, June 25, 2004 10:40 AM To: Leica Users Group Subject: Re: [Leica] Tina and Her Computer: Lightening Strike!
