The Centre for Computing History, based in Haverhill in Suffolk, does a fine job of collecting and curating the annals of the history of computing from Britain and abroad. At the Gadget Show Live 2011 in Birmingham the centre had a large display of the last few decades of computers. Here's the second part of our look back into time: we're going even further back, into the 1960s and 1970s.
