There is a project on GitHub where someone worked with the terminal and created software to interface it: https://github.com/charcole/zmachine3270. This even includes the ROMs and a pretty hacked up MAME driver. Unfortunately two of the three ROMs are bad dumps.
The new driver works relatively well, but it's difficult to test and I'm pretty sure we don't support all the synchronous mode stuff it wants from the Z80SCC.
