MAKE: AMENDS Errata for This Article

Correction for page 143
In Volume 23's "Learning Electronics" column "Zap-a-Mole," the descriptions for the 4078 chip's pins 8 and 13 were mistakenly reversed in Figure F. Pin 13 is the NOR output and pin 8 is unused. The corrected detail is included here; to download the full diagram PDF, click on the image on this article page. This correction is also in the MAKE Digital Edition.
