I dug around a bit, and found this search result on Aminet:
AmigaNOS on AminetThe version of the KA9Q tools on fish 225 is old anyway, there's a newer version listed on Aminet, but it doesn't say which version of WB it requires in the description link, so you may have to use the one from fish 225 (the original PC version was also called NOS, thus the name AmigaNOS here). However, it doesn't expose a standard sockets interface, so I don't see that you'd get much use out of it except for the tools listed along with the above search. Also be aware that the file named "NNTPKick13.lzh" is actually version 1.3 of "NNTPKick", and nothing to do with KS1.3 - it actually requires KS2.
