In "Moving targets: Elliott-Automation and the dawn of the computer age in Britain" Simon Lavington has documented[1] a computer built by Elliott Brothers (later Elliott Automation, then subsumed into ICL) named OEDIPUS that used content-addressable hardware storage. It went into production at GCHQ in 1954. The computer also gets a mention in his 2011 book "Alan Turing and his contemporaries". http://news.bbc.co.uk/2/hi/technology/8490464.stm http://news.bbc.co.uk/2/hi/technology/8490464.stm
