Vintage Synth Repair

Hi folks, you might remember me and my battery leakage issue.
Well, we still haven't found the cause of the patches not being written 
to memory. TC5514 seems to be fine.
But we have new info; The patches that are already in memory can be 
written to it - I mean you can replace the slots and the Polysix stores 
the existing patches in new slots. But if you want to create, or 
manipulate a patch on your own, so let's say you tweak some knob or 
press "manual" - then it is impossible to store such patch. Any 
suggestions? Two memories in a Polysix ? Some problem on the control 
panel line ?

When the battery leakes, it corroded the circuit lands under and around 
the battery.  I susbect it is part of the memory problm you are having 
now as i have worked on a number of these and some are fixable and some 
are give upable...g'luck  John--- In
