I still have my Spectrocam, no UV-cut.

I still have my Spectrocam--no UV cut. here I thought it was a pretty good
instrument for the time. Sadly its only serial connection and there's little
direct support for it these days. I also still have Profiler Pro and Doctor
Pro. You have to measure your chart and import the table into Profiler Pro.
I don't think I'm getting the best profiles these days with this arcane
stuff.
Regards,
David
