Finally took a couple pics of this "original" battery operated controller. Couldn't get into it but its now sitting idle since it got replaced by an easy-rain. One day it will be mine.
Not sure about how to rotate the second pic.

They are the battleships in the controller fleet, not to mention they look damn good.

Note the terminal strip connections. The company kept making this style long after they introduced a UL-listed version with molex connectors like you'd see on a Rainbird RC-7

I still have a few in service as well. We used to put in clock and advance motors in them to keep them going. One thing they will do that some of the new clocks won't do, is run a high amp draw solenoid like on some old brass valves. IMO the draw back on the Imperial, Weathermatic RM,Rain Bird RC or any of the other mechanical controllers is not keeping time on a power interruption. With all the water restrictions we can't have them coming on during the day or on the wrong day.

Why couldn't you put them on a battery backup like you would use on a computer?
