Once the logic board design flaws were discovered, a newer logic board design was produced - which included wider traces and better designed chip sockets.[9] The revised model also included 256 KB RAM as a standard configuration.[9] The 14,000 units of the original Apple III sold were returned and replaced with the entirely new revised model.
