Yes@Keith. and the exponential growth in the complexity of automobiles was responsible for dragging me kicking and screaming into the computer age. In the early 90s the Mitchell and Motors manuals representatives each quoted me in excess of $2,000 to update my shop manuals which included wiring diagrams, vacuum diagrams and testing of computerized controls. A computer and a regularly updated set of CDs from Alldata was cheaper and much more convenient. Mitchell on Demand was superior in some areas so I had both Alldata and MOD of several years. Having updated technical service bulletins and factory recalls, etc., can save a shop enough to pay the cost of either system. But I still have the 1963 Chilton manual from 50 years ago and occasionally use it to answer questions here.
One of my grandfathers was born in 1880 and died in 1969. He was one of those who never believed that the moon walk was true. Ironically, my other grandfather was born in 1895 and died in 1982 and worked as a welder and mechanic building the Redstone rockets at Redstone Arsenal in Huntsville. Technological gains in their lifetimes was Jules Vernesque.
