Hi Everybody!
I have a problem with my PolySix regarding saving patches.
There are already some presets in SRAM, but i'm unable to overwrite
it. I checked KLM-367 board and it seems that WriteEnable signal,
from IC22, Pin 10 never goes to 0, to enable writing to SRAM
i doble checked it with Mutimeter and Logic Analyzer.
Since SRAM acctualy holds presets, i doubt this chip (IC32) is bad.
When i press Write the LED blinks, and when i choose program to write
to - LED stops blinking, as it should, but the program is not
overwritten.
There was a battery leakage, but previous owner fixed it.
I also checked those fixed connections and everything seems to be ok.
It seems that everything else is working OK.
Any suggestions are welcome!
Thank you and best regards,
Peter
