A couple of items.... 1. At the Air Force Academy, the goal lights are NOT tied into the clocks. 2. There have been suggestions that all arenas have identically working clocks. I don't expect that to happen until after ALL CLOCK MANUFACTURERS get together and agree how the clocks should work, and all current scoreboards are replaced. Of course there really isn't any guarantee that the clock makers will agree to have their clocks work like the sanctioning body wants them to, or even that all sanctioning bodies will want clocks to work the same way. When I think of how many different textbooks are used in introductory calculus courses at different universities, even i am overwhelmed by the magnitude of the problem and the impossibility of a solution. charlie shub [log in to unmask] -or- cdash@colospgs (BITNET) or even (719) 593-3492
