How do you open up a case for an Apple II GS?

Thanks in advance.

Aren't there just some springy clips that you need to push in on either side of the rear, then you just pull up on the cover (from very distant memory and corroborated by this instructable http://www.instructables.com/id/Replace-an-Apple-IIGS-clock-battery/).

Remove the cover. You already know how to do this–just push in the locking buttons located on either side of the back of the case, and pull up gently on the cover.

EDIT: You just have to love the internet: http://www.apple-iigs.info/doc/fichiers/iigshardref.pdf
