TI-89 Emulator

[simX]

Anybody know any good software for emulating the TI-89 calculator? I've searched around on MacUpdate, VersionTracker, and Google, and have come up with nothing. :( I thought I remember there being one for the Mac, but I'm not sure.

if one exists, it would be at emulator.net but they appear to be down currently while they move servers.
