Looks like it still didn't recognize the output-device and reverted to
ttya.

Careful here - you just blew away the input-device setting by setting it
to an empty string.

OK, I see the layout. Seems to me we're looking for something easier to
use than bandit@XXXXX
Do
dev /alias .properties
and look for pci2 or vci0. Then you can do
setenv output-device pci2/ATY,mach64

It looks like a valid OF display type. What does .properties yield?

Was this after deleting the input-device? If either the input-device or
the output-device can't be found, OF will default to ttya.
