Amateur Radio magazine 73, issue #148. Although not directly computer related, an article on page 39 shows you how to make "Another Integrated Circuit Frequency Counter", which technically can be a method of early computing. An interesting letter submitted by Scott Marovich of Chicago, IL talks a bit about minicomputers, a few paragraphs of which are on the Intel 8008 chip. Edited by Curtis.
Sorry, no images have yet been entered. As we get more volunteers/interns we will be adding these images.
