~ P-Box Kits ~

This is one of the things that  fired up my interest in electronics - the Radio Shack, Science Fair, P-Box  kits.  There were about 30 of these things back in the early 1970's.  My first one was  an electronic metronome.  As I find other manuals, I will add them to the list.  Look at these catalog clips and let your memory drift back to the good old days!
