I'd like to know, what kind of batteries were used in the early Yamaha CS series, 20, 40, etc. We're talking about 70's here, and the memory in CSxM was a weird one, somebody told me, it as if blocked the editing of all parameters and in this way the patch was "stored". What do I do if such memory fails? How is it constructed? Is there a battery that leaks like in polysix?
