Fifty years ago, the September 1966 issue of Electronics World showed this General Electric transistor portable with a rechargeable battery. It came with a detachable base containing a clock, which also served as the charger. The battery was said to power the set for up to twelve hours after an overnight charge.
As seen from the headline, one notable feature was the fact that the set contained integrated circuits, and GE engineers predicted that all of their products would contain IC’s by 1970.
Citing the set’s reliability, GE offered a three year warranty, including the battery.
