Haha. I've been "working" on an X.25 implementation on a PC and it took me an embarrassingly long time to figure out what the hell a PAD was ever needed for.
My understanding 30 years ago was a "PAD" was the TCP/IP equivalent of a "terminal server", translating serial streams to network connections. This may be an overly simplistic view, I don't know. It's been a very long time!
Are there any public x.25 networks still operating?

Not that I know of. My plan if to use old line simulators and other tools i can find on ebay and telcom equipment reseller sites to create a "fake" private one. This is one of those projects that I'm working on purely out of novelty interest :P.
