Both 757-200 (RB211-E4) and 767-300ER (CF6-80C2) experience, both had a RAT to power flight controls only from memory (although the 767 might have done a little more, I only flew it briefly so can't remember the detail). All the 767's had HMGs (again don't remember how many) but only some of the 757's had a single HMG, the rest were non-ETOPs and had none. 757's were all passenger config, the 767's were a mixture of factory built and converted freighters.
