Has anyone completed the AS3000 mechanical keyboard mod?

Hello! I'm the one who wrote how I got through LazyDog's mechanical keyboard mod project despite his apparent disappearance from the internet (hope he's ok!): https://www.reddit.com/user/rough_draft_hero/comments/ktvcq5/how_i_made_the_mechanical_keyboard_alphasmart/

I've gotten some messages/questions over the past year and decided to ask if anyone tried this project successfully--or not. Were there issues with the PCB? Were any of the instructions unclear?

Basically, I don't want bad info floating out there when this project can cost some real $$$.

Let me know! Thanks :)
