The 5v at CLK2 is still there when the MSM5232 is pulled but i'm not getting any DCO tones no matter how many keys i press or how DCO1&2 are prpgrammed. What should i actually be getting on the DCO outputs when no key is pressed, as i seem to have a steady 4.6v on every output?

I'm getting some kind of pulse on pin 12 of the MSM5232 when i press a key, at least my scope seems to retrigger. I'm also getting a pulse waveform at the ALE pin so i assume thats working fine.

I think i'll take some measurements around the MSM5232 and IC's 16-20 on my mates Poly800 mk1 and try to work out whats not working right in mine.

Thanks again for all the help.
