I would pay or contribute 100$ for an ibm extended ansi capable telnet application for os3.x...
As far as I know, there is none, only regular ansi, not ibm extended ansi.
Tradewars looks like poop on my amiga.
There is tons of telnet bbs systems still around on telnet, and that would be a great thing to do on your amiga but it looks like shit without the support for ibm extended ansi.
As far as natami, I stopped watching it because I don't think they will ever finish anything, but I still hope.
