Condition: For Parts or Not Working
This BusLogic BT-742A EISA SCSI Controller Card is being sold as-is for parts or repair. The board looks clean with no obvious physical damage — traces, solder joints, and the external SCSI connector appear intact in the photos — but we have not powered or tested it and are not able to confirm functionality. Due to its age, it is sold strictly in as-is condition with no guarantee of operation. Please view our photo set and contact us if you have any questions.
