    Re: recommendation for slide rule ?
    From: J Cora
    Date: 2009 May 21, 09:42 -0700

    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.
