Yeah, was just curious on what was broke down. So far as specifics.
So far as the Mk2’s the buttons are caps you can remove to clean them. I’ve had it happen but I just cleaned them and there good to go.
I’ve thought of removing the rubberized coating from around the edges where they tend to stick if they do, but since learning the buttons were removable caps I haven’t had a problem enough to bother.
It will be the intern that will be on charge to read and comment the OT code then implement modern features. Good luck to him. (Everyone already read an old code from previous ppl will understand)
