I could successfully connect an #arduino Nano 33 IOT at the output of the #punchedtape reader. I am still manually pulling the tape. I think I get a parity error when there are some misalignments. I think it can be solved! It’s a really fun project and I like how it is coming together. #retrocomputing

I built a small reading circuit with some comparators. LM393 work well at 3.3V and are easy to source. I will try to connect an #Arduino soon to decode the flow of data. #punchedtape.

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
