Well, it USED to work just fine!
It's the mid-1990s, and this IT pilot fish is working on a big infrastructure project -- replacing computer control equipment that dates from way back in the 1960s.
"I was sent to a very remote site to provide software support to help with some troubleshooting on the plant floor," fish says. "There was an issue with an analog input on the new control computer. The client's field engineer was sure it was software, so I installed new software, which was extensively tested in the lab.
"Then the remote unit was rebooted -- and the issue was still present."
Next step: Swap out the analog input board. That doesn't fix the issue either, so the field engineer gets out his meter and checks the signal input circuit from the control unit to the device. No trouble found there, and the problem remains.
