the original article appeared in pop-electronics in feb 1971 
but about two months later an error was found and printed in a following
issue. no libraries carry issues that far back. can some kind soul
who has stacks of old pop-electronics in their basement look up what the
errata was and post it on the net? i'd be eternally grateful. thanks.
