I endorse Rainboe's comments. I flew the 737-200 for 13 years, and never heard of a manual reversion due to tech problems in all that time. Once, I went into manual by choice - FL100, 250kt IAS, for a trim check prior to deep maintenance. It was nothing like the sim, very much heavier, so heavy in roll that with full strength I got a roll rate of about 5 deg per second. Pitch was not quite so bad. As for landing, I would try to find somewhere calm & CAVOK with a long runway. I can't see any training value in spending time on something that is so unlikely to happen. If you have spare sim time, try an engine failure just after lift-off - it's harder to handle than a cut at V1.
