Manchester Mark 1 The first stored-programme computer, ‘the Baby’, first successfully ran a programme in 1948. It had 32-bit words and up to 8 kwords of main memory, and could execute about 830 instructions/second.

In 1998, a noodle-timing programme won a 50th-anniversary programming competition for a replica Baby.

By the autumn of 1949, the Manchester Mark I was running, with a drum memory supplementing the electronic memory.
