Updated and working with a Raspberry Pi2
10-18-2008. Today I got proof this stuff really is in my genes.
While I was cleaning out my grandfather's shop I came across copied textbook pages.
My first thought was how did TM11-458 pages I copied end up out there.
When I looked closer the pages were 1950's Bell training material.
My grandfather most likely copied them from my greatgrandfather's books.
The current paths and wiring were all color coded just like I do.
