In 1983, a CSNET-sponsored project at Purdue implemented a system for running TCP directly over X.25. It required that you had "real" X.25 access on your machine, not just a PAD; in our case, we used a board from ACC, with certified ROMs from Interactive Systems (I think). In the US, it's not a terribly cost effective way to operate (SLIP is much cheaper, since it isn't necessarily subject to usage-sensitive charging), but it might be useful in Europe. I'm sure the CSNET folks can still supply a version of this if someone is interested. chris
