I just did the same thing, put a 18G Western Digital SCA (80 pin) with an adapter into the zip space of a 7300/200. You'll need termination. The SCA adapter may have a terminator itself, look for a TE jumper. My adapter doesn't so I've got my old 700MB Quantum still in there. One way to test this, I've found the external SCSI bus to be more tolerant of termination problems. It'll still probably screw up, but it'll probably boot first. It's easy to switch the cable to the external bus by swinging the drive portion of the case up, and just moving the cable to the other connector. I don't know the legality of this, but Drive Setup is easily modified to support most SCSI drives-- instructions are easily found by google. (it just involves using ResEdit to change a text string in one of the resources, it's really easy). I've been considering throwing my drive into an external case, because of the heat and power considerations. To do this, I have: (1) a case (2) a cable (3) a terminator (4) a SCSI card The external bus on the 7300 is only half the speed of the internal, so I was planning on using an old 10MB/s card (same as internal speed). The external case also makes it slightly easier to use for testing other computers. -- Dana [EMAIL PROTECTED] -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
