Telling the story of how the place was actually used over time was more important (and interesting) than being able to show how it looked when it was first built. I suppose there's a parallel can be drawn with old computers, *whilst sufficient numbers in as-new condition exist*. Actually even then, maybe that only applies to commodity machines - low-volume machines are probably equally interesting both in original form and with any modifications that owners may have made over the years. I'm sort of sitting on the fence on that one; I'm not sure whether I agree or not. But it's certainly food for thought, and 5155's are going to be common as muck for a long time to come (second only to Osbornes I think; I don't want to see another one of those damn things in my life!). Ensuring that the ink on the note isn't going to fade in a matter of years, or any tape used isn't going to cause stains that will damage the case etc. :-) It's the irreversable stuff I don't like - people cutting holes in cases or tracks on PCBs to modify them etc.; reversible things I have no problem with, providing there's sufficient knowledge out there to put things back as they were (and any parts needed are easy to get hold of). cheers Jules
