I have found it on the Kylix installation. But I did a quick search of 
Delphi NetChat and I found it immediately. It should be in the Demos 
folder. Demos->Internet->NetChat. You may also download it from 
Internet, where a Brazilian guy has made it available:
http://simbolussi.ddns.com.br:8088/TESTE%20DELPHI%207/Delphi7/Delphi7/Demos/Internet/NetChat/

Yes it is a network app, but it can be used locally, just by connecting 
both sides via localhost (i.e. 127.0.0.1), the loopback interface, which 
can be used whenever you want to connect TCP/IP server-client on the 
same machine. It's fundamental to test network apps locally before 
deploying it.
Just search for "windows localhost", and you'll get the Microsoft 
documentation about it:
https://learn.microsoft.com/en-us/windows/iot-core/develop-your-app/loopback
and other contributions which may be useful.

That way you'll be using tools which are widely used and tested, and not 
very special ones which may fail outside a particular environment.
