What brand TCAS? Are you using a 28v or 12 v system?

The sim provides the TCAS input for the display (which is the only simulated
part), so brand is not relevant. Likewise for the electrical system.

What kind of display?

In the Baron, the display is a Sandel ST3400. In the airliners, it's part of
the overall avionics suite, which I think is made by Honeywell and other
subcontractors.

Are you actually flying now, or still playing MSFS?

If you cannot tell, then it doesn't matter.
