I'm a little late on this thread...but have something to report that may or may not be useful. I have a G4 MDD 1.25 dual with an Adpatec SCSI PCI card Model 2906. It runs perfectly using OSX 3.9. and 9.2.2. It came with a CD & software for Power Mac. It did not specify OS version. I have the box if you want to know more. I purchased the PCI Card for a G4 450, so it's probably about 8 years old. It worked fine on that machine. The Card has an internal connection, I suppose to support an internal HD. I never used it. When I want to use a SCSI HD with my MDD, I shut down, then power-up the SCSI HD, then turn on the mac. It is recognized immediately on the desktop. In OS 9.2.2 I use the same procedure, then use SCSI Probe to mount the Drive(s). Hope this doesn't confuse the issue. Jonny ** Also possibly of interest to some, but vastly obscure, I am using the SCSI HD to move data processed on an old Apple 540 C laptop running OS 7.5. I need to use that OS to run an image application (kodak) only available on that machine. I fiddled around. When I first tried to connect a SCSI drive with the laptop (special adapter necessary), I used an old 4 GB SCSI drive. It wasn't recognized. As I had been previously advised by the LIST that OS 9.2.2 will not recognize a drive over 128 GB. I applied that logic to the laptop running 7.5 and used a 540 MB SCSI drive. It automatically mounted & worked. I do not know what the upper size limit is, I just went with the smallest SCSI drive I had. /// >Hi Eric, I tend to agree with you that (It would be cheaper and >faster for Cecil to buy a new ATA driveand write the SCSI up to >experience.)
