My netowrk is a mix of OS X, OS 10, and RasPi (Buster, Bullseye, and Bookworm). I have on e or two favored machines that are only 9.x capable. They can see the internet enough to come to AppleFritter, MacRepository.com, and MacintoshGarden.com. They just cannot see anything on my local network, nor be seen by any local machine. Pinging the IP address gets a hit but trying to connect fails as there seems to be alack of a common protocol/protocol version.
What could I do to make these things see each other?
TIA
