ught he was a George Carlin and far more interested in what was in the girls panties than he was in actually teaching the algebra class he was being paid to do. So I quit school and went to work fixing what was then a brand new tech, TV's at 14 yo. You would not be far wrong to say I grew up with a hot soldering iron in one hand and a scope probe in the other by the time I hit 17. But real math? Nope... What little I can do was taught to me by a TI SR51 or a log-log-duplex Pickett slipstick. What you are doing might as well be black magic to me. But if you have an electronics problem, I can probably help. [...] Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
