Puzzle 5 - Foil

#TuringChallenge

Alan Turing provided the theoretical underpinnings for the modern computer. The image of the microchip on the foil is a recognition of that achievement.

Complete the two sunflowers with four letter words spelt outwards from the central 50s, so that adjacent words differ by exactly one letter.

The example on the left shows how BANK can be changed to NOTE in four steps.

Once you have completed the sunflowers, find the central four letter word which differs by exactly one letter from each of the two words it’s connected to through the microchips, to solve the puzzle!

On a red background with some of Turing's notes and diagrams is a blown up version of the microchip from the bank note. The sunflowers at each end now have letters in and are joined to each other using the chip as a sort of maze.
There is an example as…
