For grins, I’ve put a somewhat restricted working copy of my original Megahost Support BBS online. Four nodes running on a Windows 10 32bit NTVDM virtual machine under Proxmox. It uses the Netfoss fossil driver and associated Net2BBS application to provide telnet access. Also Trade Wars 2002 in a door. I’ve yet to get file transfer functional.

You can check it out at telnet://donmankin.net:1000

I’ve provided one RIP bulletin (09) for fun. The latest Windows client SyncTerm supports RIP if you want to check it out.
