This is an Orange Micro Grappler scsi 940UW PCI card. Specs: This top of the line Grappler SCSI 940UW pipelines data at a blistering 40MB/sec for up to 15 SCSI daisy-chained peripherals. That's 8 times faster than Apple's original built-in SCSI port. Customers for this Ultra Wide SCSI-3 interface are expected to be users of high performance internal disk drives (7,200 or 10,000 RPM).

I will basically take best offer on this one. All parts are in mint condition.
