From the BBC:

“By Shiona McCallum Technology reporter GCHQ has released never before seen images of Colossus, the UK's secret code-breaking computer credited with helping the Allies win World War Two. The intelligence agency is publishing them to mark the 80th anniversary of the device's invention. It says they "shed new light" on the "genesis and workings of Colossus", which is considered by many to be the first digital computer. <snip>” Full text and photos: https://www.bbc.co.uk/news/technology-67997406 These photos are fascinating, particularly the one showing a separate large set of plugboards. My assumption is that the Colossus shown is one of the later production model.
