I've been to the RICM and while the warehouse is kinda neat, everything is just sitting rusting. They're not doing anything with what they're sitting on, and a lot of it is very poorly protected/packaged. The warehouse was enormous, filthy, and had large doors open to the outdoors (far down the other end, but still.)
They're also (reportedly) rather anti-Apple/Macintosh.
The warehouse is like the scene at the end of Raiders of the Lost Ark, where they file away the artifact into a box to be placed alongside countless shelves of other artifacts. I wouldn't say it's filthy as much as I would say it's dark and cluttered- they can really use some more structured organization and inventory management. They get donations of really large equipment, and their first priority is that it has a place where it won't be scrapped. But they have a ton of stuff, a small staff and modest budget, so they do what they can.
One story they told me is that they are contacted by TV and movie production companies that need period-specific computers and props, so they'll pack up and send out various equipment and lease them out. They come back cleaned up and in better shape than when they sent them out.
They're also (reportedly) rather anti-Apple/Macintosh.
