Comet combines a Telnet client and a tn3270 client in one program. It's getting a bit long in the tooth, since it was written primarily with black-and-white Macs in mind. But if you want a single application that will automatically choose the proper type of terminal emulation without you having to think about it, Comet may be for you.
"Frankly, I prefer Comet to its more advanced sister, dataComet. Everything I needed was already in Comet."
—G. Vinton Palazzolo

Also, if you have an older Mac, be sure to check out the "Classic" applications page for more options.
Finally, take a look at ALEMIA if you think you know that name of an application, but aren't quite sure.
No, I don't accept reviews anymore for these older applications. With the creation of this page in the Orchard's late 2005 redesign, I only accept reviews for currently-developed applications that work on Mac OS X (or later....whatever that might be!!).
