There quite a lot out there, few getting much use though.

List here: https://www.telnetbbsguide.com/ Other interesting telnet servers include JPL: telnet horizons.jpl.nasa.gov 6775 and telehack.com.

There's even a telnet WOPR emulator: https://github.com/abs0/wargames

Do any of them give you a busy signal and make you re-telnet?
