I second this. The most amazing thing to me is that they still keep many of those really old machines and peripherals: the Colossus and more, up and running.

It's one thing to see those historic computers on display, it's a whole new level seeing them running, producing heat and noise!

That colossus is a replica, the original machines were all destroyed

That's true. I forgot that. Still impressive to see live action though.
