I have certainly used a large number of the DX50's and DX2/66's and never had any trouble with them. The DX2/80 part has always slipped into the cracks pricewise, and thus I've never used one. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" -Terry Lambert UNIX: live FreeBSD or die!
