My business partner has many hours as copilot in the King Aire.
A couple of years ago asked if I still had the USB external 3.5 inch floppy drive. I dug through my closet and found it. He borrowed it to do some update to the King Aire. It was laughable, an aircraft with millions, and it uses a 3.5 inch floppy.
Kinda like the McLaren F1 that REQUIRES an old Compaq laptop to update it. Multi million dollar car, fantastic in every way, and a 20 year old Compaq to keep it running.
