I've just got my hands on a traxcopier duplicator. It copies 150 CDs at a time and has come with only one cd writer installed. Does anybody have any information on this machine? would i be able to install DVD writers? would i need to upgrade the firmware? Would i need to change the controller card? I'm thinking of just taking to a friend of a friend who is good with computers and letting him have a go at "modifying" it. Any ideas?
