You can use a Yamaha YM3623B to take a standard digital out from a CD or DAT
player and then get digital out along with sucode out.  The chip also has outs
for copy disabled/enabled, and the category (DAT) or other than DAT.  This is a
very common chip (in digital audio) that is used in the D/A section of many cd
players.  If the CD-ROM drives had a chip like this in it, you could patch
the output that list copy/no copy, otherwise you could take the raw data from
the digital out and process it yourself.  Yamaha's address is:
YAMAHA Systems Technology

They don't give samples, but the chip can be obtained through Marshall.
