This is a 2-computer example, but if there were multiple machines, Ethernet requires a hub (typically around $65 now). Localtalk just daisy-chains. You run ordinary phone lines from one phone-net connector to the next. You can network a small building that way if you want.
Put your name in the "Owner Name" box; put a password in the password box, and put whatever you want your computer to be called in the "Computer Name" box. Most likely the names will already be filled in, but you can change them if you want. The password is what you'll use to gain access to your entire computer if you connect to it from another machine.
Turn on File Sharing. Click the "Start" button in the Sharing Setup window. Then close the control panel.
Go under the Apple Menu to Control Panels, and select "Users and Groups".
Double click on the "Guest" icon, and check the box labeled "Allow guests to access this computer". Then close the control panel.
If you want to set up userids and passwords you do that here as well. A Group is a collection of users; you create a group by clicking "New", naming the group, and then dragging user icons into it. When you set up access privileges, you can assign privileges to a single user or to a group. You also
can assign privileges to Everyone. If you do that, then users can connect without having to supply a userid and password.
I continue to be amazed that anything as kludgy as Windows came to be the dominant way of running a computer. I guess I can see why big corporations like it, as it has lots of complex management stuff in it, but why anyone else tolerates it remains a mystery.
