Hubbard) Newsgroups: comp.sys.nsc.32k Subject: How does the Dallas Semiconductor chip retain the time? Message-ID: Date: 29 May 91 14:08:00 GMT Sender: news@daver.bungi.com Lines: 15 Approved: news@daver.bungi.com Not having any specs on my chip (I got it from Steve Liggett), I was wondering.. I figure it either has a very small lithium-type battery someplace (in which case I wonder about its lifetime), or a small nuclear reactor of the Pons & Fleischman (or Fleischman/Pons, for our english readers) type. If it's the latter, how often do I need to sprinkle it with heavy water? I suppose it might also be a sliver of plutonium and a miniature thermocouple, but that's REALLY farfetched! :-) :-) :-) for the sarcasm impaired. Jordan
