What do you have to have in order to build a computer? By that, I mean how do you know which chips, ICs to use, etc? Are there core (really important parts) of the digital logic ICs, for example, are there certain ways to align up chips so that they act as a processor? What do you have to do in order to build a cpu? From looking at various websites in the webring, some people have used nothing but TTLs in their computers. Others have built CPUs for their computers. Until I stumbled upon the webring, I could never really find anything other than "how to build our own computer" websites that showed you how to select an existing PC motherboard, and put in various ATI and NVIDIA video cards, to build a "customized" Windows PC.
