When I was a young boy my father was a computer programmer. After the Army, he worked at places like IBM, Bell & Howell, Honeywell, etc. I went to work with him a couple of Saturdays (he pretty much worked 60 or so hours a week). There were large rooms of "computers" - air conditioned rooms behind glass, with refrigerator sized reel to reel magnetic tape units. And there were punch cards everywhere. They were also all over our house. They became the default note paper. It's kind of funny how far the form factor has come. Sorry, back to memorabilia!
