@mint there's bbs numbers in the USA if you don't mind having to pay long distance and likely a low baud rate because voip + old c64s and the like not doing it anyway.
I called one bbs number and got a magicjack, dude should have been using a voip provider and modem pool and all. Some guy on Reddit spent $$$ to get a isdn emulator setup to drive a 56k isdn setup and all (since to do 56k uplink you need isp modems and similar otherwise you're capped at 33.3 like with dreampi)
