That empty space hasn't existed for months. Against the wall where one of them lived is now a wire rack full of computers, terminals, and boxes of the cables that used to be on that pegboard. This leaves the other pegboard nearly inaccessible.
One option would be to strip all the cables off, sort them into piles, identify the ones I absolutely need convenient access to, put a supply of them onto the single pegboard, the rest into storage, and the other pegboard into the trash.
But I don't want to do that. I want to find a way to have both of them in a small a space as possible and still accessible. So, what I want is a frame of some sort that will support them standing upright (rather than just leaning against the wall) and allow them to slide or roll lengthwise (widthwise?) from the deep, narrow space I keep them in into the middle of the room for access, and then slide/roll back.
Easiest solution is probably just some casters on a 1xN platform and some 1x1 struts to support the pegboard as it leans slightly back. Anybody have a better idea?
