I frequently talk to people about evidentiary breath testing.  I explain the weaknesses of one infamous and silly device called the Intoxilyzer 5000.  This is the breath test machine used by the Harrisburg Police Department and other surrounding police departments.

After I explained a lot of the shortcomings it seems that about 9 out of 10 people say something like this: 

Dude, you mean that if I plead I will have just got convicted by a breath test machine that was state-of-the-art in 1984.

I say:

Yup.

It’s true all versions of the Intoxilyzer 5000 breathalyzer are run by the Z80 CPU.  Pretty funny if it was not for the fact that people still blow into it all around the Harrisburg area and it is used as proof of a DUI.
