Not a museum or archive as such but in the UK there is this https://www.rmcretro.com/

Has a large collection of old systems and games, magazines and anything else they can get hold of. It's also open to visitors.

That is two museums. It's in the title: "Hands-On Vintage Technology Museums" and mentioned all over the front page.
