Hi Tony,

I left this for a few days in the hope that somebody who knows more than next to nothing about NSMs might turn up! From what you've written, the fault seems to be within the CCU and possibly a poor joint? Do you have the large schematic with the circuit diagram of the CCU? You could get in there with a logic probe to attempt to follow the signal if so. This would obviously be a bit easier since you have a working unit to hand but no doubt still time consuming. If you want pictures of the relevant CCU section, I can do that for you.

Norman.

I have a Prestige II with an ES2 system that acts odd. Lets say to make a selection 123. Press 1 - OK, press 2 - OK, press 3 and the 3 goes into the 2nd digit place so it's reading 13. Additional pressed buttons will show up in the second digit place with 1 staying as the first digit. What makes it more odd is that yesterday something happened and it worked correctly until it was turned off and on again, then it went back to making the strange selections. I have another credit/selection computer and that one works correctly all the time. Tried powering it up with the cabinet switch open and closed with no difference.
