Portrait of world's oldest computer rediscovered in Manchester cafe

Painting of Witch computer had been missing for years and was the subject of a nationwide search

A long-lost portrait of a historic computer - built in 1951 and now the oldest working digital computer in the world - has resurfaced on a cafe bar wall in Manchester.

The artist John Yeadon first saw the Witch (the Wolverhampton Instrument for Teaching Computation from Harwell) in 1982 in the Museum of Science and Industry in Birmingham. He was fascinated, even though it had become a sad ghost of its former glory at the cutting edge of computing technology.
