Yes. And I thought about Mims when I was typing that. But I never said that I thought it unacceptable for ANYONE to put hand-drawn schematics into a commercial product -- I said that I would not do it. Having said that, the appearance of informality and DIY flavor inferred by hand-drawn schematics was completely appropriate to the Forest Mims line of books.Well I'll be... sorry about that WBahn, I misquoted your post in my last reply. It's this last phrase that I was referring to when I brought up Mr Mims.
