Many kinds of hardware are getting smarter. I was a bit startled when I took my new shaver apart and discovered that it has an IC of some kind inside it! Probably some kind of power-control chip running switching hardware -- the thing can be charged from 110 or 220 without any flipping of switches, and it knows when its battery is getting low. -- Mars in 1980s: USSR, 2 tries, | Henry Spencer at U of Toronto Zoology 2 failures; USA, 0 tries. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu
