Qualified SCSI HBA Cards Pro Tools|24 & MIX Systems With Pro Tools 5.x for Mac OS 9 For maximum track count, use of a qualified SCSI HBA (Host Bus Adapter) card is required. Optional SCSI HBA cards bundled (by Apple) with some G3 and G4 computers are not compatible due to lack of support for external drives. Depending on your computer certain ATTO ExpressPCI and Adaptec Power Domain cards are qualified for use with Pro Tools, refer to your computer's "SCSI HBA Card" section for details at the following links: SCSI HBA cards are not required for Pro Tools III Systems. Note: Adaptec 2940UW and 3940UW cards with G4s are unsuitable for full Pro Tools performance. Due to PCI bus related issues the Adaptec 2940UW and 3940UW SCSI HBA cards are unable to provide full Pro Tools performance. Additionally, Adaptec has discontinued these cards, and as a result there will be no future engineering support from Adaptec on these cards. |
