Monongahela Incline closed for computer problems

From the P-G:

The Port Authority's Monongaghela Incline between Carson Street and Grandview Avenue is closed today due to computer problems.

A Port Authority spokesman said shuttle buses are being used to transport passengers who normally take the incline.

The incline also is expected to be closed on Monday and shuttle service will be provided.

I can only assume that the Port Authority is using this time in an attempt to resurrect Charles Babbage in order to have him help clear some jammed punch cards.

But computer problems? Seriously? This thing used to run on friggin' steam, right? This is basically the same amazingly complex principle as a wheel and pulley, right? Where exactly are the computers entering into this?

Does this mean that there's some evil HAL 9000 like computer managing some complicated "car go up/car go down" program that the mission is too critical for humans to be in charge... or is it more likely that some PAT employee downloaded some sort of malware program while surfing for porn on the machine that's supposed to log their time sheets?

If the latter, I'd recommend not touching anything when you ride that thing next time.
