Have you downloaded the schematics? check them out because that part of the circuit is quite straightforward.

Hi Mike, thanks for the reply.
I just replaced IC34, but unfortunately the problem is still there with the "3" button and the tape switch not working.Any other ideas about what to look at? Or is there a way I can narrow down the issue with a multimeter?I did also just do the internal battery mod (mine was a mk1 with no 2032 present), and that is working great now.Thanks again!
