In certain B&W (and Beige) G3 models, SCSI drives were offered as an option, which usually meant one or possibly two 9 GB Seagate drives and an Adaptec, but Apple-ROMed, UW-SCSI controller. At that time, SCSI was the performance option, and ATA was the low(er) cost option. The particular Adaptec controller used UW-SCSI drives, which have a 68-pin interface for a 16-bit-wide data path. Traditional SCSI has a 50-pin interface for an 8-bit-wide data path. OWC may not be the best place to look for SCSI drives. A possible alternative is the ACARD "SCSIDE" adapter, which allows you to connect an Ultra ATA (UATA) drive of truly un-SCSI-like capacity (nearly 1,000 GB) to the Mac's SCSI controller. ________________________________________________________________ Not entirely correct: My Beige G3/300 miniTower had a SCSI card which was ATTO, with Apple firmware which stopped it using its external connection. I flashed mine back to ATTO spec to add further SCSI drives and it worked well. I still have it now, but like my G4, it hasn't been used in a while. Best beloved uses the G5 and I'm happy with my MacPro... -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
