My mother got her MSc. more than 50 years ago. She was a sort of a pioneer as she run climate models on computers. I remember we had #punchedcards (that were unfortunately lost in a flood many years ago). She has found a #punchedtape a few weeks ago. I remember back when I was a kid I wanted to build a system to read it. It may become an interesting project… #vintagecomputing
The #phototransistors work fine. This base should keep them aligned properly for the punched tape reader. Let's hope my printer is not going to die while printing this one #3Dprinting. #arduino
