I come up with tm10079 for the tech manual, should be around $50 or so when downloaded (printed always costs about 2x's) from johndeeretechinfo.com when searching just the 200dlc it would contain the nuts and bolts of the repairs, specs, guidelines, etc. TM10076 should be the test manual, and it is quite spendy but without the hardware/software to plug into the excavator much of that info will not be a huge value to you. What kind of info are you looking to access? There is also numerous componenet manuals that just cover specific sections, like the engine, etc.
