Vintage Calculator Tour - documentary
This video is a documentary/tour of 26 calculating devices, most of them vintage, that I have in my collection. I have selected those from the collection that have personal meaning for me because I used or owned them during my childhood and adult life, or because they have significant historical importance. For the oldest types, I include a brief primer or tutorial on his the devices were used. I end with the most recent models from my personal calculating history, even those could not be considered as vintage.

Sorry that this video is only standard definition. At an hour and 45 minutes long, the high definition video that I shot is apparently too much for my video editing software, and it would always crash when trying to render a high definition output file. I only got it to work when I selected standard definition output.
