The first three volumes of the Ciarcia's Circuit Cellar books are now
available for online viewing (but not downloading) at Google Books.
These books collect Steve Ciarcia's 70s/80s Byte columns - lots of
interesting stuff.

I have no relation to these scans but thought I'd pass the link along
since these books come up now and then on the list and have lots of
classiccmp-relevant content.
