The ASCII controller was the 7171, developed by Dr. Wehrle's team in the
Glendale Lab in the 1980's.
My car pool buddy at the time, Tom Murphy Jr. (the other Tom Murphy for
those of you in VM) was the lead
developer on that box.

In days of yore, there was a hardware solution. The 3174(?)
Asynchronous Emulation Adapter. I don't remember the configuration
I tried, but it made an (independent vendor) 3278 behave remarkably
like a VT-220.
