I have successfully restored old plastic to near its original condition by wiping it down with a "hot" solvent (I use acetone). Be advise that what you are actually doing is removing the very top layer of the plastic, thus exposing the original color. How much damage you do depends on the quality of the plastic, how "hot" the solvent, and how carefully you go about the work. A little trial and error on the underside will give some insight as to how well it will clean up. A little furniture polish or similiar at the end will generally gring back the luster of the plastic that has been deadened by the solvent wipe. Please, no flames about this. I do not recommend, nor do I personally use this procedure on any equipment that I deem too valuable to "clean up". I also have discolored HP equipment which will stay that way. OTOH, I see no reason not to clean up old Commodores, and the like, this way. As far as an ADAM goes, the owner will have to decide. I have a couple and put them in the same catagory as Commodores, i.e., clean-up candidates.
