I use Apple's MPW on this 8500 running OS 9.1 and I occasionally do the same thing on an SE/30 running 7.5. MPW is a shell application that is based on the C-shell of UNIX of old. It doesn't act as an interface to a kernel as in UNIX. Rather it offers kernel-like commands that are executed by the application itself. It also serves as a text editor built for writing C or perl. I love it. But it's not UNIX as is OX10 at least before it became a matter of gesturing rather than commanding. The terminal emulators of old for the classic OS absolutely depend on a serial port that needs to be connected to a serial port on the UNIX box or a modem that can get there with a transmission link. Doing it using ethernet between OS 7 or even 8 and OS 10 after 10.3.9 is impossible because OS X has disabled AppleFile protocol over ethernet. For me the emulators stopped working when I retired and lost my dial-up account on a Dec VAX. On OS 9 there is MacSSH PPC which will allow a remote logon to OS-X and Linux over ethernet. It does work but it's not the text editor that the MPW shell is. MPW offers a remote ToolServer that can run on another classic box and connect using AppleTalk. It will not run on any OS-X box. There are some Mac:SSH application versions for OS 7 and 8 but I have tried them without success. Stairways Software has Interarchy, an FTP and HTTP client that will run on OS 7,8,9 boxes and communicates for file transfer with OS-X. There is also NetPresenz from the same company that will serve FTP and some HTTP while running on OS 7,8,9. I use both for communicating between Linux and OS-X and my favorite MPW on OS 9. But it's not a login shell emulator. My guess it that the VT220 got hooked up with a connection to an OS-x USB port with a serial to USB conversion adapter. It might work with a cable to an older Mac with an RS422 Printer/Modem port. The cable could be tricky though because converters don't always honor the negative signal requirement of RS 232. Ask if you want to try that. I did come up with a way to talk to a Garmin GPS receiver with RS422 on an SE/30. It's also conceivable that a an old 1200 baud modem could be used to communicate with a Mac that has a built-in modem. My G4, running 10.3.9 for reasons above, has a place for that but it appears to be limited to FAX only at least with Qwest as a telco. Hard wired to another modem? I haven't tried.
