OK, you clods! You have messed with my mind, and now rather than straightforwardly ordering a new scope I am bidding on eBay! For a Tektronix 465. Most likely I will rue the day, although the guy that is selling it is rated very positively (99.6%) and has a string of glowing feedbacks about three miles long. Anyway, we shall see. Of course, I have not yet won the bid. Thanks for all the good advice. It is always interesting to ask a question on the piclist, and then wade through the responses to distill out the wheat from the chaff. (Both "wheat" and "chaff" being relative terms, of course -- there is no bad advice, only advice that does not comport with what I want to do). -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
