Irrigation technology has come a long way, as you can see from this August 1977 feature on “Space-age technology for irrigation controls” from Weeds, Trees and Turf (the former name of LM).

This article shows how an irrigation system developed by Rockwell International for the Johns Manville corporation was the first to use a microprocessor in its controls. Even back in 1977, this Model Keyboard Controller Series could service up to 24 stations and handle four, 14-day schedules.

This controller included a calculator-type keyboard to program the device. Other notable features include skip days, an automatic syringe for cooling and disease control. Another bonus is the deliberate “mushroom” appearance to blend in with the landscape surrounding the device.
