Comment on Yes, in the 1980s we downloaded games from the radio
vk6flab@lemmy.radio 4 weeks agoThere was also a system where some TV screen pixels were used to send data, but I’m struggling to remember how you were supposed to get it into the computer.
I suspect that you needed to build some light sensor with a serial cable, that you held to the screen, but I’m not sure.
This was in the Netherlands, not sure if it was done elsewhere.

I had heard of this but your comment sent me searching for more info. I think you might be referring to Visicode.

That looks interesting, but it’s not ringing any bells.
