Spot the anachronism?

Spot the anachronism in the history of computing section of London's Science Museum?

Given the Acorn/BBC Computer Literacy Project get together in 2008, and rumours of an upgraded display, the computing section was disappointing, despite the decent history and exploration of the contributions of Charles Babbage and Ada Lovelace (which includes Babbage's brain and several machines built using Babbage's plans).
