Our first visit to Bletchley Park.
On this trip due to time constraints we only visited the National Museum of Computing to see the Colossus computer. We will visit again to see the rest of the Bletchley Park heritage site.

This computer is a bit more modern. It is an Analogue Computer of 1970’s vintage. I used to program one of these when I was doing my Electronics degree course!
