Is SCSI termination correct for all tested combinations?
The fdomain card should have a jumper (w4 usually) for termination. Is it
in or out? If the board is not labeled, I can look up the setting.
Are all devices on one cable or do you have both internal and external
cables in use?

Maybe testing the nec as the only device with proper termination at each
end would help.

They are iso9660 and if you mount them on a dos or windows system they
should even be readable, but with 8.3 filenames. I have tested a lot of
them on my funky 2x soundblaster, which often gets errors on silver
CD-ROMs and they play well. If you can pop them into somebody's w95 or dos
pc, it will assure that they are readable. It's possible that the kid's
CDs appear OK because the directory is small, hence less transfer needed
to mount it.
What message do you get when you try to mount these CD's?
