Re: HP 11C Good news, indeed... Message #7 Posted by Vieira, Luiz C. (Brazil) on 3 Jan 2003, 2:53 p.m., in response to message #6 by Erich Neubacher
Hi;
As I probabyy mentioned at the time I read and answered your post, there is a common problem I found in many Voyagers, being them HP11C, HP15C or HP12C (all types): bad soldering contacts. I cannot say anything about the HP10C because I saw only one till now and the HP16C, because the only one I know so far is the one I have.
Anyway, by simply resoldering all IC's terminalsn in these machines allowed me to bring a dozen of them back to life. In many cases, the symptons used to come and go from time to time, sometimes weather dependant (metal shrinks and expands with temperature, so bad contacts come and go with temperature variations, if bad contact occurs; in Brazil we call it "solda fria" or "cool-solder", being cool a low-temperature reference, not a good-stuff reference). Have you observed this? Is it cold in Deutschland for these days? You are in Deutschland, aren't you?
Well, time will tell. I do not think the HP11C's are guitly as charged, after all. They are good, reliable calculators. Maybe after more than 12-15 years they allowed themselves to look as normal as other calculators... Who knows?
My best regards.
