The pedantic nature of this list makes it a real treasure.

Simple GOOGLE and Wikipedia are buried in too many "definitive" wrong 
answers.  Such as calling 36 pin Blue ribbon "Centronics", "DB9", or the 
historic/antique uses of the yellow and black pair in phone wiring (NO, it 
was NOT "always" for second line)
