I know that a company I worked for bid for the platform information system to be revamped from old CRTs that would draw at 1200bps to show next train info across the system, and at that point, the PDP11 was still being used. I got to spend a few hours in there with it trying to debug a serial protocol that, again, was poorly documented, that was being used to render that information.

"Not fun". Kinda glad we didn't get the contract.
