What is required to network my MacOS machine with a Next machine ?
You can connect the machines using ethernet, either 10BaseT (twisted pair) through a hub or 10Base2 (thinnet) using the standard BNC connections, coax cable and terminators. (NeXT computers include ethernet inerfaces on the backplane.) Of course, the Mac requires an ethernet interface and you need to assign IP addresses to the connected machines. Read the System Administration docs on configuring NextStep for a mixed network. You should use NetInfoManager.app and HostManager.app to configure a NS/OS machine for TCP/IP networks. SimpleNetworkStarter.app is intended to simplify setting up NetInfo networks, not mixed networks. Once your TCP/IP network is set up, you can use a FTP client on the Mac (e.g. Fetch, Anarchie) to move files back and forth to the Next machine, using the IP address, user account and password that you’ve set-up on the Next. The MacOS OpenTransport TCP software is very useful if you have more than one TCP/IP setting (e.g. 192.168.x.x) that you’d like to maintain. Re
