Well, yes, but I was trying to see if you could use the existing circuit before removing the connector.
I can make out some of the ICs; the HD64 is the microcontroller, and the AMIC is the ROM for it. The DS1603 is a dual elapsed time counter, it counts the number of seconds the unit is switched on for, and also the number of seconds it's switched off !.
Unfortunately I think it's going to be a herculean task to try to re-use the existing circuit at all, so just remove the connector and solder to that.
