Nowadays, I dunno. Um, possibly this is a reflection of my ignorance, but I always figured that if it walks like a duck and quacks like a duck, you might as well treat it as a duck -- isn't there an agreed-on standard for the forward drop of a 1N34? (I don't have a spec sheet handy.) If so, do I really care whether it's germanium, silicon, or praseodymium in there? -- That's not a joke, that's | Henry Spencer at U of Toronto Zoology NASA. -Nick Szabo | uunet!attcan!utzoo!henry henry@zoo.toronto.edu Brought to you by Super Global Mega Corp .com
