Its the side of the the chip nearest to where you plugged the max 233 in.
Count down untill you get to eleven.
I managed to solder it by luck rather than skill.
I like the razor blade idea.
I was thinking soldering a solid wire like a fuse wire to it.
Then normal wire to that.
Is there anywhere under the board that can be soldered to,that anyone has found.
Would it matter if the wire touch pin 10,cos i read it does,nt actually do anything.
