I looked at the site and they have an incredible collection of
manuals.  I downloaded the manual
for the 4080 of which there are around 60 html
pages using a download manager.  Also I want
to thank you for the photos particularly the
link to the zip files which made the download
very easy.

I bought two slide rules on ebay  neither were the 4080 model as the
autobid is a nuisance.
Now just waiting for the sellers to ship.
