Re: DX7s main board connectors?

Thanks to all for the helpful info and ideas.   I was able to remove the connector and substitute a standard 0.1"  (2.54mm) header.   Power is back on.  :-)
 

 I found that I have version 1.2 OS EPROM.  Any benefit in upgrading to latest version 1.3 OS?
 

 Cheers,
 Mike
