The National Museum of Computing is to hold the first UK vintage computing exhibition on 19 and 20 June at Bletchley Park, the Second World War code-cracking centre.
Speakers include Sophie Wilson, one of the brains behind the Acorn and later the ARM microprocessors that now power most mobile phones, and Tony Sale, who led the team that rebuilt Colossus, the world's first electronic digital programmable computer, which helped decrypt German military signals during the war.
Delwyn Holroyd will discuss the rebuild of an ICL 2966 mainframe, and Adam Bradley will highlight the museum's Cray supercomputer.
Chris Smith, who engineered the design and technology of the Sinclair home PCs, will also discuss the rise of computer gaming.
Other speakers will discuss the rebuilding of the world's oldest working computer, the Harwell Witch, and an Elliott 803B.
