Ruth,

Having spent the better part of the week in Nashua, I now have lots of new
"points of interest" I'd like to see covered in the newest manual updates.
Being one who has read the I&DS from cover to cover many times, with ample
interstitial diversions through the related source listings, the I&DS is a
very valuable resource for providing a macroscopic understanding of source
and internals that would otherwise take too many work cycles to fully com-
prehend.

In relation to Galaxy, obviously, a section and/or new chapter related to
the Galaxy and the "configuration tree" mechanism used to partition Galaxy
resources (in this case the memory) would be a monumental resource.  This
is a great new feature and interesting functionality within VMS and would
permit those of us who hack the kernel to conceive and develop new and in-
teresting applications to exploit this new capability.

I'd be interested in a section and/or chapter devoted to the console and 
the support it lends to both the Galaxy (and specifically, memory mgt).  
Talking with Greg this past week, I'd very much like to see some detail 
relating to the console support/changes/modification and firmware support/
changes/modification in relation to address translation/TB invalidation/
etc.  PFN management both intra- and inter-Galactic instance would/should 
be topic for consideration.

Also, new "global buffer objects" have been introduced.  I've already been
bitten with a driver I modified for Fast I/O and a well known application
already using these features.  If you could (I know this is supposed to be
memory mgt), a brief diversion into performing I/O (Fast I/O) using these
new objects would be very welcomed and appreciated.
