On 13 January 2011, the [[Computer Conservation Society]] announced that it planned to build a working replica of EDSAC, at the [[National Museum of Computing]] (TNMoC) in [[Bletchley Park Museum|Bletchley Park]] supervised by [[Andrew Herbert]], who studied under Maurice Wilkes.<ref>{{cite news |url=https://www.bbc.co.uk/news/technology-12181153 |title=Pioneering Edsac computer to be built at Bletchley Park |work=BBC News |date=13 January 2011 |first= Mark |last=Ward |access-date=2011-01-13}}</ref> The first parts of the replica were switched on in November 2014.<ref>[https://www.bbc.co.uk/news/technology-30131447 Museum switches on historic computer].</ref><ref>{{cite book |last1=Hartley |first1=David |last2=Herbert |first2=Andrew |title=Making the History of Computing Relevant |chapter=EDSAC Replica Project |volume=416 |date=2013 |doi=10.1007/978-3-642-41650-7_27 |at=''9 Current Status'', pp. 307–308 |language=en |series=IFIP Advances in Information and Communication Technology |isbn=978-3-642-41649-1 }}</ref> The EDSAC logical circuits were meticulously reconstructed through the development of a simulator and the reexamination of some rediscovered original schematics.
