However, the actual costs of all the are not zero. We are talking bronze age embedded systems not iPads. Nothing is easy there. Limited resources - not money wise - may also have been an issue coupled with time pressure.
You need a DAL A system for this. If developed early enough clearly possible with special hardware. However Boeing tried to get away with a cheap solution which is now extremely costly. Wonder how much people at Boeing were in the know of this.
