David, SIM forum has some very intelligent and knowledgable people discussing embedded y2k. It is just fun to poke around on the internet, and trying to find some real good and valuable information. As I read, I post it for others to use. Also, in this way I can always refer back to information I had found before. This is another interesting post. David Hall is one of THE authorities on embedded Y2k, IMO (read his biography!) Regards, John _______ '106. Author: David C. Hall ( dhall ) Date: Jul. 2 5:08 PM 1998 There are many "Urban Myths" being propagated throughout the media and the Internet. However, one thing I have learned in the last four years - there is no absolute when it comes to year 2000. Every one of the absolute statements I or anyone else has made over the last four years has been shown to have exceptions. The only thing absolute about Year 2000 is that impacts will occur in places that will astound and surprise everyone. We need to assume nothing, even in the face of overwhelming evidence. Our system/equipment might be the one exception to the rule. An example is elevators. I usually quote Otis and Dover that none of their elevators, when used as standalone devices, have Year 2000 problems. I then extrapolate that into elevators, when used as standalone devices, should not have any Year 2000 problems. Last week I got an e-mail from the UK about a standalone elevator that does indeed have a Year 2000 impact and will stop soon after "00" hits its microprocessor. Something to do with a filled buffer. Point is, no one should ASSUME anything without testing THEIR systems based on THEIR standard of Year 2000 compliance. Sorry to have to say this, but it seems to be reality. We must test each and every one of OUR systems and microprocessor-based equipment to BE SURE that we have no Year 2000 impacts. Since we really don't have time to do that, I recommend that a risk-based triage plan be adopted. Dave Hall dhall@enteract.com
