MTBF is “Mean Time Between Failures”, and a recent article will lead to a slight increase of the C64’s MTBF. It states that on old C64 was responsible for the electronic displays on the main station of Dortmund, and it lately quit its service after 20 years. The funny thing is that they need to repair it, as a new system would cost three million Euros. An expert from Munich was commissioned to repair the computer, but he did not arrive yet. Rumour has it noone in Dortmund knows on which rail he’ll arrive.
