This sounds really good. Which version of Windows95 driver do you have? vpmd.vxd
or vpmd2.vxd? If you have the first one your Scanner might not really be a
D600, because all the D600 we´ve heard of use the second one.... I´m not really
sure about this, but reporting it to us, would be really nice.

Yes, that´s because there´s no calibration, yet. The code for the
software-calibration should be in version 0.2, but it´s not intended for use,
since the scanner has its own ability for calibrating. The scanner is able to
use its full 30 bit for calibration, software has only 24 Bits...

Well, open the scanner´s cover. Near the hinge you´ll find 2 skrews. Simply
remove them and you´ll be able to open the scanner. On the side where all the
connectors are, you´ll find a circuit board with 6 ICs on it (well in the
Colorado Direct there are 6, maybe you´ll find more or less...). Well write
down the things written on these ICs.

Well, this seems to be a problem of the CD-Writer... Furthermore we don´t know
how the sent material changes when there´s another device on the parallel
port... it also doesn´t work if I switch on my HP Printer...
Thank you for supporting us.
