In the Release Notes for 3.0 under AppKit, the following statement is made:

"	Under NeXTSTEP 2.0 JPEG images were written using a very early draft of  
the new TIFF standard. Because of numerous revisions to this spec, JPEG images  
written under 2.0 are pretty much _not_ compatible with anything, except that  
they can be loaded under NeXTSTEP 3.0.  JPEG images written under 3.0 are  
compatible with the TIFF 6.0 draft but cannot be read back on earlier versions  
of NeXTSTEP."

Does anyone have access to these early drafts?  Even a good idea of what the  
various private TIFF tags mean would help.  I would like to write a conversion  
program which reads in old NeXT-specific JPEG TIFFs and write out JPEG TIFFs  
which are compatible with the other platforms which are used by people I send  
images to.  A quick investigation shows that it doesn't appear to be a simple  
matter of changing the TIFF tags to standard numbers - the format of the extra  
information has also changed quite a bit.
