The 1052 already has user-programmable lowpass/highpass/bandpass digital filtering. Pretty cool. John

You can buy some extra GHz by entering the license code. This is _not_ new nor hidden! Pere

I think you will find that somewhere in the small print it says that you agree to all their draconian terms and conditions by opening the shrink wrap packaging and clicking on OK or "I accept" during the installation where a long screed you are supposed to read is typically displayed. I am amazed that they were quite so heavy handed though! I take it that they had a warrant to enter and search your premises. Regards, Martin Brown

Part of which is called BOM? See above, i can repeat it one more time. "Cost" affects the decision to manufacture or not to manufacture the particular products." Price is the result of negiotiation between the seller and the buyer, ant not the pure function of cost. You will sell with a huge profit if you can or with a huge loss if it is the only way to recover at least some of the cost. -- Andrew |
