Inside the 1200

[CritAnime]

Ok so i opened my 1200 up and found a odd yellow wire that is coming off the budgie chip and going to some tiny little chip at the bottom of the system which then seems to be going to a blank space. Any idea what this is?

Also there is a header inside that has a cap on it that looks like it's intended for a drive or soemthing. Any idea what that is?

It's a rev f mother board

Newbie to the insides of the 1200 so sorry if these sound like silly questions.

Btw the header is not the hdd header as I have my cf connected to that

And the header is p9b but I cant take a photo of it because the camera won't focus properly on it.

there is also this one

Revision F motherboard? I've never heard of one. Can you take some photo's of that section of the board where it says F?

It's me been slack. The motherboard says 1b but there's a sticker that says rev f. That must have something to do with the wires maybe?

Also the p9b header. Is that the rtc connector.

This is what I am talking about.
