Colossus computer conservationist Tony Sale dies
Tony Sale, the brilliant engineer who led the rebuild of Colossus, the first modern computer, has died aged 80.
The mammoth project to recreate the code-cracking Colossus capped a career built around electronics and computers.
Most recently, Mr Sale drove the campaign to save Bletchley Park, where Colossus aided Allied code-cracking efforts during World War II.
