I recall a customer producing Mylar had a system (early 1970's I think) that would run in autonomous mode for about 45 minutes. After that a lengthy shut down was required to remove the goo and restart the process. IBM systems with sequenced power were supposed to be sequenced down. Many of the products took a lot of TLC before they would restart after a Emergency shutdown or power dump. Most of the time they survived the event without damage.
