Small businesses can sometimes be famous for their stubbornness. After all, once you've got something that works, why change?
That's what one automobile shop in Gdansk, Poland has managed to do. The company's business has been using a C64 -- the same 1994 model with 64kb of RAM and a blistering 1MHz CPU -- for 25 years.
According to a user translation of the original post, the C64 handles the drive shaft calibrations. Custom software was built for the auto shop and even though the system was "flooded through a leaking window ... and most likely shat on by birds" the aging icon of computing is still going strong today.
If it ain't broke...
