In October 1947, the directors of J. Lyons & Co (think - teashops, nippies, bakeries, ice-creams, steakhouses, hotels, Wimpy Bars and Dunkin' Donuts), decided to take an active role in promoting the commercial development of computers. In 1951 the LEO I computer was operational and ran the world's first regular routine office computer job.
"In 1964, a computer - the IBM 1401 Data Processing System - arrived in Iceland, one of the very first computers to be imported into the country… The chief maintenance engineer for this machine was Jóhann Gunnarsson, my father. A keen musician, he learned of an obscure method of making music on this computer - a purpose for which this business machine was not at all designed… When the IBM 1401 was taken out of service in 1971, it wasn't simply thrown away like an old refrigerator, but was given a little farewell ceremony, almost a funeral, when its melodies were played for one last time. This "performance" was documented on tape along with recordings of the sound of the machine in operation." The whole story with samples, pictures and video at Jóhann Jóhannsson's site. [via]
