Nellie: School Computer
First broadcast: 5 February 1969
While many pupils might wish they could hand their schoolwork over to a computer, the boys of Forest Grammar School in Berkshire have turned a computer into schoolwork.
Dubbed Nellie, the machine can be programmed to solve mathematical equations or even play music. Lessons also include computer maintenance - something of a necessity, considering the likelihood of Nellie crashing.
