On a peripherally related note: 
ISTR that HDDs are assembled in a Nitrogen filled, clean room environment, sealed against Oxygen and obviously dust. I never questioned this, figuring Oxygen is deadly to anything subject to corrosion.
1) is this true?
2) if a drive is opened is it toasting, just waiting for the timer to pop?
3) can it be re-assembled in a home-mad clean room box, similar to a sandblasting box?
4) is Nitrogen available in quantities less, and more convenient, than a welding tank?
I've always wanted to make a clear plastic cover for one of the (Quantum?) drives with the stamped Aluminum pan cover. It's part of the long term goal of creating a ClearProtoHoaxMac of one of the Frog designs or a modified Mac design.
Lately I've been leaning toward a taller IIsi/BeigeG3 Mobo w/low profile PCI cards kinda deal. A clear lidded HDD would be a killer feature.
Were Teflon lubricants available at time of manufacture, what was the original lubricant spec?
