Assuming they weren't upgraded, the plane was 30+ years old when it was decommissioned. Normally, I'd say the market for equipment that old is third-world countries, and the old planes need old parts, but the 747 is a big plane. The other buyers of old airplanes are companies like UPS and DHL, but I'm not sure they want them that old, and they'd probably upgrade the avionics.
