What specs do flight computers have?

[LambOfGod]

Hey, I'm interested in what type of computers aircraft companies use. i.e Boeing, Airbus, Lockheed etc..

I have some Q's - And is anyone here an aircraft computer designer or something along the lines?

1. What processors do they have?
2. RAM?
3. Who build them? (Microsoft, that would excite me)
4. How much?

I know they're a hell of alot better than all the mostly pos computers out there.

And I searched, I could only find post's critising FBW and A'bus.

Thankyou gentleman.
