I just recently got an Indivision ECS for my Amiga 2500, those things are held on by the power of prayer heh, I had to do some rigging to make it stable also had to move a capacitor on the main board, to even make it fit in place and my mobo was suppose to be a revision that you didnt have to do that with, uuuuuggggh, thankfully my soder skills arent bad.
