In a fairly recent electrionics trade mag, one of the columnists was commenting on a DoD spec which required that a part have a MTBF (Mean Time Between Failures) of about 77 years. I think this part was in a field radio or maybe it was a field radio. Perhaps the originator could get together with whatever contractor fulfilled this spec. --- Dan Tilque -- dant@twaddl.LA.TEK.COM "Computers are useless.
