I'm using it successfully on my Adaptec 7880 (aka 2940 UW) motherboard SCSI.<br>

I too, have not gotten any response when I asked the Photo Scanner<br>
contact listed in the PhotoSmart developer's kit.<br>

<p>
I have a method for correcting for the negative's orange mask and <br>
inverting it to a positive. It seems to be fairly good, giving<br>
a result that is similar to the Win95 software for the scanner.<br>
Now if we can get automatic frame location, we could automatically<br>
scan a negative strip.<br>
