1st of all, you are asking this question on the wrong list. The Performa 475 is NOT a PCI Power mac. 2nd, if I don't miss my guess the connectors or ports on the back of the Performa 475 are a serial, modem, and 25 pin SCSI. So if you want to use this external CD rom, you'll have to use an adapter cable. Like I said before, I don't know whether they refer to it as a 25 or 50 pin Centronics, but it definitely needs to have a 25 pin DB 25 end on one of the ends of the cable. The other will look like the male equivalent to the centronics end that you see on the back of the CD rom case. If you have a working CD rom in the Performa 475 then it is likely set to ID 3 (a popular default setting) which is also what the external will be likely set to too. You will end up with a conflict if you try to run them at the same time. Look for an ID controller on the back of the CD rom case, and if there is none, you'll likely have to remove it from the enclosure and manually change the ID to some # that you do not have a device already set to. So with conversion cable, a terminator, and proper ID settings, there should be no problem hooking them up and getting the CD rom to work providing it is in working order.
