The article showed how to put the chips together so that they work. This oversimplification that is so prevalent today that you can "just put it together like the databook shows" is a bunch of crap in so many cases. I had a client once that felt anything short of a Cray-1 was a 'cookbook' design and should take no more than one day to design/build/troubleshoot. The fact is, find a working wheel or else prepare to go through a painful process re-inventing your own wheel. Flame off.
