Is anyone familiar with 50Hz to 60Hz converters. Are they expensive? Would using one be recommended for taking a personal computer to Europe? Thanks, Paul Seelaus (seismo!presby!skip) Division of Cardiology Research 51 N. 39th St. Phila., Pa. 19104

Give me a break! 50-60 Hz converters for a personal computer? This really shows the maturity of computer technology: someone can use one without knowing much about electricity or the basic ideas of how the thing works. You ain't likely to find a 50-60 Hz converter anywhere for any reasonable price today which would be possible to carry anywhere on an airplane unless you don't take any clothes with you. Why? Because the thing would have to work by totally reprocessing the electrical energy contained in a 50 Hz sine wave using some kind of power supply which would then have to power synthesize a 60 Hz sine wave. Think about it. Your computer is likely to work at 50 Hz but that depends on the adequacy of its power supply. The 50 Hz will not be filtered as well by capacitors but the voltage regulator chips will probably not care one whit. I am a bit disgusted by people who don't understand how things they depend on work.

Well, Professor Abeles, aren't you being somewhat (like a lot)
heavy-handed (mouthed) to someone who asked a simple question.
As far as I know, it is not a requirement in most Computer Science
courses for people to be expert EE types. Whether or not you
think it was a naive stupid question, it was asked, and as far as
I am concerned, most learning occurs by asking questions and
reading. You could have saved yourself from reading flames and
mail by patiently answering the question.

Should a secretary need to take EE classes just to use a word-processor and not disgust you in the process? Give me a break -- while it's useful for people to know such things, there is no reason for everyone to have to know it. dirk grunwald university of illinois
