I own an iMac G4, running OSX Tiger. I have managed to get the following working to my satisfaction on it:-
iMessage - I wrote a proxy that runs on a modern mac that bridges between my iMessage database and XMPP. I use the XMPP client on the iMac G4
SSL - I'm using a proxy called WebOne that runs on a raspberry pi, so most apps on the mac can see most of the modern web over http.
Mail.app for email. Using fastmail with an app specific password. It's missing the last 15 years of security updates but I'm sure this is fine.
OmniWeb for web browsing. It's faster than safari and is approximately as broken
NetNewsWire Lite for RSS. Works pretty well.
