Time to get rid of some stuff...this was to be the crown jewel of my little GA sim, but I've since scrapped the sim. This HSI came from an AST-300 FTD, and still powered up & moved before I pulled it.

Should be ideal for sim use....I just never got around to interfacing it before getting rid of my old sim.
