technical reference choices

[LeonKatz]

here's a question I feel that only the experts can answer
went to my local MB dealer and purchased the Model124 service manual library Version2.0 thinking that it would enlighten me on the in's and outs of repairs and tech references of my restoration project 87 300Dturbo, well as I scroll through the library I sudenly notice when I magnified the text because I could not read the Tiny words or pictures , the more I magnified the more distorted it became which caused me to shift my little brain into overdrive to get a full understanding, this is really something when you have to translate wiring diagrams (routing/terminations and color codes
and wire numbers/sizes, now the question is it better to purchase the tech reference books ? or just fell lucky because I have all the tech information at hand and it takes up less space, more picsels or more books? interested in getting your opinions
