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.
The calculators are, in order of presentation: 1) Abacus (Japanese/soroban type) 2) Napier's Bones 3) Pangborn adding machine 4) Burroughs model 50501 adding machine 5) Slide rule 6) Sterling "Dial-a-Matic" adding machine 7) Electronic desktop calculator 8) Bowmar 901B (Craig labeled) "Bowmar Brain" 9) TI-2510 "Datamath" 10) Litronix 2230 11) Rockwell 63R "Scientific Slide Rule" 12) TI-30 13) Novus 4525 "Scientist PR" 14) Novus 650 "Mathbox" 15) Novus 750 16) TI model SR-51-II 17) TI-58 18) Hosiden/Satolex "Calcupen" 19) Sharp EL-5805 "ELSI MATE" 20) Radio Shack "TRS-80 Pocket Computer" (re-badged Sharp 1211) 21) TI-66 22) Casio SL-760 credit card calculator

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.
