I accept viewed from the 7billion people problem olpc achieved only millions. None the less, olpc did achieve the scale of millions. It says quite a lot that 3 millions is failure. I guess it depends how your goal is measured.
Searches peter out around 2017/2018 for people trying to do what you want to do. the qanta screen was interesting but it didn't become ubiquitous, so its down to the scavengers who have an olpc and want to hack. Circuit diagrams I think will be easy, block-logic-structure stuff.
I did find people who cheated and used X $DISPLAY. I don't think thats quite the goal here :-)
