Well, this part is just plain uninfomed:
"Science museums around the world have long collected computing
kit. But there are only three institutions actively growing
collections of outdated computers and restoring them to working
order: the UK's National Museum of Computing (NMOC) at Bletchley
Park; the Computer History Museum in Silicon Valley; and the Heinz
Nixdorf MuseumsForum (HNF) in Padaborn, Germany."
Only three? I can name a half-dozen more off the top of my head
without even googling.
And the HNF doesn't do anything to get something running afaik....
