Link from Ed Yardeni's site to a good article on embedded system Y2k:yardeni.com (Yardeni site)tmn.com (Article) ' Embedded Systems and the Year 2000 Problem (The OTHER Year 2000 Problem) Draft of 30 June 1998 Copyright 1998 Mark A. Frautschi 49 Merrion Court Lutherville, MD 21093-1845 (410) 453-9250 frautsch@tmn.com tmn.com Abstract: There is another Year-2000 risk, distinct from the more widely reported risks concerning impending failures of computers and software which represent dates using two digits for the year. The risk involves date sensitive embedded systems (built-in silicon chips, such as microprocessors, timers, sequencers and controllers) which are essential to the operation of a vast portfolio of infrastructures; from medical pacemakers, to buildings (phone, security, heating, plumbing and lighting), to transportation, to financial networks, to just-in-time delivery systems, and so on. According to a recent study, the firmware (permanently loaded software) that enables these chips to run is date sensitive and not Year-2000-compliant in approximately 1 to 3 percent of the 50 billion embedded systems that will be installed worldwide by the end of the century. This small fraction will fail, causing the systems they control to begin failing around 1 January 2000 and for the first few years of the new century. These failures are coupled with significant factors mitigating their diagnosis and repair, including the absence of reliable documentation of Year-2000-compliance of date sensitive chips produced over the past few decades, posing formidable assessment issues. ...
