No .....But i am looking at changing the 4xxx chips to the right of the battery, The battery at some point has been changed but i see no damage to the board.
I also plan to change the e-proms.

I have now fixed all the problems, Regarding the storing problem i found in the manual that you have to input 95 + enter to enable recording.
Never saw that one before.... :D

Yes it's certainly a good synth, It has the sound of a prophet 5 i used to have.

It has very fast envelopes and the lfo's are super fast.

Next i will recap it and give it a good clean.

I am referring to a rev 2 p5 i had many years ago...This opera 6 has has ssm vco's even though it has dco writen on it.

The filter is sweet and deep.....I will be using this synth for time.. :D

Well - it is "DCO driven by VCO" :-) I probably repeat myself, but this is very interesting DCO design. Two SSM2031 VCOs are used as master oscillators for DCOs (instead of crystal oscillator or system clock).
