[DeTomaso] NPC - Window memories

Everyone's accounts working with early Windows versions made me smile. 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.

Ironically, last night we were cleaning some shelves in the basement. I
pulled out a 1/2 dozen windows 95 books. They are headed for the wood
burner if anyone want's one!
