I wonder if this would be useful as a dataset for economics research. Lots you could conceivably pull from the ads: fine grained pricing, company formation and destruction, trends in standards for components, performance specs of components over time. All at the time of the Cambrian explosion of computing
Also wow this is a gargantuan effort. I scanned thee equivalent of like one issue of Computer Shopper one time and it was painful. Kudos to the author.
