Teaching kids at school about IT history and 8 bit computing
yewtube?
is that 4chan-slang for jew tube? replace the prefix "yew" with "you" and avoid that potential trap.
As a kid, I loved the in-detail descriptions of technology. So maybe more of that, how the CPU works. Like actually go into detail.
