At one point I still had a stack of punch cards that contained the very
first Fortran program I ever wrote. I haven't seen them in years so I
must have thrown them out. I remember taking that class at Gonzaga here
in Spokane way back when I was in high school. It was a special several
week program for interested high school students.

When I was in college, we still used slide rules my freshman year and when one of the dormies got a TI 4 function calculator (with LED display) it was like looking into the future. I used IBM punch cards when taking Fortran classes. PCs came out after I had started my first job and used DOS (I still have a Microsoft DOS manual). My boss only bought one PC for the engineering department because the price was so high and after watching a sales demo he asked me what I thought of the machines. I told him I could see where everyone in the office should have one and he looked at me like I was crazy.
