Armagh Observatory's Edwardian-era computer
A rare mechanical calculator has been discovered among the archives in Armagh Observatory.
Dating from the start of the last century, it was found recently while the observatory's collection of artefacts was being catalogued.
BBC Newsline's district reporter Gordon Adair has been finding out about the machine's fascinating history and the observatory makes an appeal for information.
