[sdiy] TI to buy NatSemi!!!!!

In junior high school, 1971, I learned Brahma Bulls Raised On Young Grass
Become Valuable Grand Winners.

I used to help my dad sort the resistors when we would build our latest
Heath Kit.

There is utility in learning some "old school" lessons. Nothing teaches
logarithms, significant digits, and order of magnitude estimating like
learning to use a slide rule. I taught my kids how and it helped them in
math.
