Hint:
The theoretical breadboard used for artwork layout purposes in this
book is specified with a total of 550 contacts arranged in a main
matrix of two blocks of 47 rows of five interconnected sockets, and
a row of 40 interconnected sockets down each side of the main
matrix. Such a theoretical block will hold upto six 14-pin or nine
8-pin dual-in-line integrated circuit packages, together with their
ancillary components.
Remember though, that you may need to adapt the theoretical circuit
layout to suit whichever particular breadboard you buy.

Hey, wait a minute — I’ve mentioned a few times already this
mysterious component called a dual-in-line integrated circuit,
but what is it? Well, Photo 2.3 shows one in close-up while
Photo 2.4 shows it, in situ, in a professional plugblock. The
pins (which provide connections to the circuits integrated
inside the body — integrated circuit — geddit?) are in two
