Dick,

Many thanks for this information. Unfortunately the book itself is not of 
much use. It was copyrighted in 2000, and all references to software, 
hardware and concepts is circa 1999 or earlier. The only versions of 
Windows referenced at all are Windows 95, 98 and NT, and 95 gets most of 
the attention. In addition, a large number of the vendors listed in the 
appendices are no longer in business or have been merged with other 
entities, and many of the assistive devices referenced are no longer 
manufactured. Even taking the publication date into account, referring to 
TeleSensory as manufacturing "cutting edge braille displays" is rather 
silly, as they sold their braille products to FreedomScientific about the 
time the book was being written, and they had not come up with anything 
new int he braille display area for some years before that.

Perhaps this is why the book is now freely available - no one would buy it 
now.
