The official TI-73 Explorer emulator, TI-SmartView 73 1.0 is now available on TI web site.
Up to some weeks ago, it was only available on a demo CD shipped for free to North America residents. The matching form seems to have been removed.
The links aren't available publicly on TI web site to my knowledge. I've just made various tries by modifying other TI-SmartView emulators url, and this time the "73" suffix worked although it didn't work some weeks ago.
Just follow the links at the end of the TI-Bank news:

The emulator comes with OS 1.91 and Boot Code 1.3007.
