Got me curious so I looked it up. The loss of the No.1 gen bus took out power to the lone stick shaker motor, the left stall warning computer and the slat disagree indication. The left and right stall warning computers did not compare information by design anyway. Good memory there. The accident report dinged the stall warning system for overall lack of redundancy. Lack of data comparison between sensors / computers being highlighted. And here we are 40 years later.
