Who cares
let the place go - the whole thing about technology is the latest and greatest, this harking back to the valve is just sad.
I say they just model the place it in 3D, release it to the world, and let that be that.
It is pathetic, those machines can be replicated on a device the size of thumbnail now, and frankly it wasn't that impressive at the time, ohhh look I have found a pattern. People were a lot simpler back then, can you imagine that motley crew up against the best of the best today, it would be a whitewash.
Take Bletchley park and turn it into a datacenter, that could work. But, don't preserve the crusty crumudgeon of a place that it was.
Oh and didn't IBM equip the Germans.
