So you are saying I should go into buisness, open a salt mine, and hey! I could make some side cash doing EMC testing.... Cool !!!! Any takers?
I wonder is gold mines are good.. There are a lot of old abandoned gold mines in Colorado. :) Mat > -----Original Message----- > From: [email protected] [SMTP:[email protected]] > Sent: Thursday, August 05, 1999 10:26 AM > To: Aschenberg, Mat; [email protected] > Subject: RE: cost effective EMC facility > > > > It could be very cost effective if EMC testing is a by-product of the salt > mine :-). > > =================================================================== > > > > > "Aschenberg, Mat" <[email protected]> on 08/05/99 08:16:54 AM > > Please respond to "Aschenberg, Mat" <[email protected]> > > > To: "'[email protected]'" <[email protected]> > "Lacey,Scott" <[email protected]> > cc: "'Price, Ed'" <[email protected]> > "'[email protected]'" <[email protected]> (bcc: Robert E. > Heller/US-Corporate/3M/US) > Subject: RE: cost effective EMC facility > > > > > > I was under the impression that we were discussion the "Cost-effective" > emc > testing solutions, not the cost-absurd solutions.
