Jules sayeth: Yes, I believe that opportunity is still available. But I don't think that's necessary. I think one could be analyzed adequately if it was removed, de-vaccumed, and a hole of 1cm is drilled through the face where the affliction is at its worst. Then blow the dust away and see what you got. If there's something biological there, isn't there a simple test you can apply (say "hello" to it and see if it responds)? If it's delamination, I think it will be apparent at the cross-section. The drilling would not be that trivial, but doable. If I get time I'll try this, just to put this to rest once and for all. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
