We assume you mean the Fortune computer that was marketed 5 to 7 years ago, a UNIX computer that used UNIX System 7. Any terminal emulation that can be defined in "termcap" can be used with this system. The VT100 emulation provided in many Macintosh telecommunications applications would work.
Here are three Macintosh-to-Fortune 8025 Communication solutions.
* NCSA Telnet is probably the best solution. Telnet is a solid, feature-rich, public-domain, VT100 emulator. It requires an Ethernet connection and a Kinetics FastPath, if you are connecting via PhoneNET or LocalTalk. Telnet supports UNIX FTP.
* Kermit is a file-transfer protocol. The public-domain Kermit package for Macintosh also provides terminal emulation.
* MacTerminal or equivalent creates an asynchronous connection with ASCII text transfer only.
For more information, search for NCSA Telnet, Kermit, or MacTerminal.
