On their marks
Machines spanning eight decades of computing battled it out on Saturday in the first race of its kind.
Computers ranging from the world's oldest-working computer, the 1951 Harwell Witch, to the tiny 2016 BBC micro:bit, competed to calculate the most numbers in a Fibonacci sequence in 15 seconds.
This gallery walks you through the machines that took part, from the slowest to the fastest, and you can read more about the race at The National Museum of Computing in the UK, here.
