On November 21, 2007, the University of Manitoba said goodbye to its beloved mainframe computer by holding a New Orleans-style jazz funeral for its 47-year-old IBM 650, Betelgeuse. In case you were wondering what an IBM 650's specifications were, according to this Columbia University site, the 650's CPU was 5ft by 3ft by 6ft and weighed 1,966 lbs, and rented for $3200 per month. The power unit was 5x3x6 and weighed 2,972 pounds. The card reader/punch weighed 1,295 pounds and rented for $550/month. The memory was a rotating magnetic drum with 2000-word capacity (10 digits and sign) and random access time of 2.496 ms. For an additional $1,500/month you could add magnetic core memory of 60 words with access time of .096ms. Big Blue sold some 2,000 of the mainframes, making it one of the first successfully mass-produced computers."
