I was going through a cupboard a few days ago. Got 9 keyboards on end in a box, that has been stored for so long that the box has rotted (it's an outside cupboard that was under a leaky roof before I noticed and had it repaired. I sense a certain amount of restoration is going to be in order, but at least I know I have a nice supply of AT and PS/2 keyboards, when I add them to the shelf I have several stored on inside. It's a low shelf, with keyboards angled on top of each other, so no weight issues and minimal space needed.
