Spelling error on my part, but it did make for an interesting pun. I can't define Normal. I'm intested in hearing all opinions of what is the oldest comptuer still in "normal" use. From there I'll make my own personal decision of which I feel provides the best answer. That doesn't mean anyone else has to consider my choice to be valid. I'd accept the government, and actually I rather expected the answer to be some government system. That was the other place I figured the best answer might turn up. Some kind of factory automated system that still uses its orginal systems simply because its working so has no reason to be replaced. -chris <http://www.mythtech.net>
