Konrad Zuse finished his Z1 in 1938. The computer was freely programmable. It worked by controlling mechanical switching elements that pushed metal pins into two different positions: position “0” and position “1.” This binary principle is still the basis of every computer.

Manchester is where the important early computer development in the UK occurred; Turing spent a lot of time working with the Manchester Baby: https://www.scienceandindustrymuseum.org.uk/whats-on/meet-ba...
Reading was Digital Equipment Corporation (DEC)'s centre in the UK. While it was an American company they had a huge estate here. I have a soft spot for their machines so I'm curious to see what this small museum managed to pull together - I know they reached out in some of the relevant Facebook groups for personal stories of DEC and their machines: https://www.readingmuseum.org.uk/whats-on/reading%E2%80%99s-...

In Germany we've quite a few more or less good equiped museums.. The one in Stuttgart, South of Germany, is located at the University and is quite interesting. May be the upper List will be of good inspiration for you!
Definitely book a tour if you go. Speaking to the volunteers about how they used the machines on display is a fantastic way to experience part of the living history of computing.
It reminds me of the computing museum near Google main campus in Mountain View, California.
And from a more local angle & purely for a lovely day out, may I recommend a trip to Cork City and a wander through George Boole’s old stomping ground in UCC.
Enjoy reconnecting!
Cambridge has a bunch of computer stuff. I think Raspberry Pi started there.
