I find it useful to draw analogies with user friendly things like personal computers. Your three cases then become:
>1) ADD AN OPTION WHICH ALLOWS MACHINE TO PERFORM FUNCTION >IT COULDN'T PREVIOUSLY DO. Add a sound card to an old 386 - the sound card must be CE marked and shown to comply with EMC requirements but it doesn't affect your old 386. >2) ADD AN OPTION THAT DUPLICATES AN EXISTING FUNCTION; Add a second sound card (or whatever) to your old 386 - again, the sound card must be CE marked but it doesn't affect the old PC. 3) ADD AN ADJACENT MACHINE THAT WORKS IN TANDEM WITH THIS MACHINE AND COMMUNICATES WITH IT; Add a printer connected via interface cable to the parallel port of your old 386 - again the printer must be CE marked, etc, but still your old PC remains the same. If this analogy is an accurate reflection of your situation, then none of your situations require looking at old installed equipment. You need to look at the add-ons.
