Not to be too nitpicky, but it is not used to run "the auto shop". It is essentially part of a drive shaft balancing machine. We should think of it as the embedded controller and display of the machine to understand why nobody would replace it while it is still working. And I'm sure there are plenty of old machines around where some electronics inside are literally or very similar to general purpose computers of the era. But often the physical integration into the machine hides this. Nevertheless impressive this thing is still running!
