And I remember seeing my first Calculator in 1971.  Four function:  add, subtract, multiply, divide.  Cost:  $400.  I remember taking my first exam as a Junior in Fluid Mechanics in 1974; all the other guys had calculators, I had a slide rule.  That night, I bought my first calculator, a Texas Instruments one, used, about $100 advertised in the campus newspaper.  But, I got the highest grade in the class on that exam....and yes....I still have my slide rule, and know how to use it!!  I laugh about it all now.

  Yes, you are correct.  But they were kind of limited back in those days.  Now, a modern car has many.  I remember my first contact with digital stuff in 1971.  Nand Gates and Nor Gates.  Boolean Algebra.  Things sure happened marvelously from then on.  And there was this marvelous electronic machine, used a language called "Basic".  Soon after, more languages...like "Fortran".  Oh my!!  And about 10 years later, some geeks put together something called a "Personal Computer".  I couldn't imagine why anyone besides an engineer would want one.  I was wrong.
