A couple of friends and I paid a special visit to Swindon to go here today
https://www.museumofcomputing.org.uk/It's quite small, a couple of shop units, but it's packed full of computers and consoles, many of which can be used.
There is a room with some Amigas on display; an A500, A500 plus, A600, the A500 mini, and an A1200 running classicWB and WHDLoad. There is also a CD32 in another room.
We spent a couple of hours looking around the exhibits and recommend it.
