Bernina 830: can't open lid and is noisy?

Hello, I hope someone can help me.
I got a beautiful 830 on ebay that looks like it is brand new. But I am having a couple of problems.
1. I can not open the lid on my Bernina 830 -- it is a 1981 model. I have posted on a Bernina site and have been told that it just lifts and that there is no lock, however I can not pull it up and either can my husband. I am wondering if this model might have a catch on it. I've opened the face door (where the light is housed) and can't see any catch.
2. The machine is noisy. Mostly it is the bobbin case rattling, because when I take it out it is not as noisy (however it's not quiet either.) Maybe it isn't an original case? Don't know for sure. Did the original cases have a BB on them?
3. There is an issue with the foot pedal & cord which I won't get into because hopefully we have already figured that part out.

Once this is sorted out I think it will be a great machine and am really looking forward to getting it all working.

Also, I need a source for some bobbins for this machine.

Thanks very much for your help. I do appreciate it.
