There are about six rows of integrated circuits and very few passive components. On the top row there is a potted module. There is a two megahertz crystal mounted between the first and second rows. There are two round stickers, one green and one blue, stuck to the upper left integrated circuit at the insertion end. All but one of the integrated circuits have sockets. At the left corner of the component side near the extraction end there is a eight pole DIP switch.
