I experiencing some problems on two different dual boot Macs. One is a G4/667 Powerbook, 30GB HD, 512MB RAM. This PowerBook needs to boot in OS 9.2.2 to drive a BetterLight Scanback camera. The camera is SCSI based and utilitizes a Ratoc CB31 Pismo cardbus. My problem is the camera software quits unexpectedly during a scan but contiues to record the image to its own hard drive. I can't however re-start the software (does not see camera back) until I re-boot the entire system. This only happens with this Mac, when I connect a G4/466 (OS 9.2.2 only) tower no problems at all. I've spoke with both Ratoc and BetterLight and have followed their instructions for proper set-up. My thought is OS 10.2.8 and OS 9.2.2 on the same hard drive is the problem. The other dual boot Mac is a DP 867, 60 GB HD, 512 RAM unit that also has both OS systems installed. This one runs QuarkXPress, Photoshop and Illustrator for my Art Director. He locks up alot and experiences problems in Quark that I can't reproduce on any other Mac that runs only one OS (9.2.2). Can I safely trash OS X and run OS 9.2.2 on these Macs?
