When the unit "acted up" it would do this:
1 enter 1 + -> 1
2 enter 2 y^x -> 2
Or just simply ligt up the bottom bar of the second display position.
Where can I get the service module?

Just asking. I have this 41C that I bought in 1979 that started to act up after I cleaned it. I think I got it fixed though, by removing the modules (Circuits1, Math1 and Quad Mem), but it would be nice to have the service module
