Need help with a 68K Mac board

I just received a Micronet Raven ProPDS card (2 NCR UWSCSI chips on an 040 PDS card for Quadra era Macs) and can't get it to work. This card was supposed to be the fastest SCSI you could get on a 68K Mac: "The new Raven Pros offer access times as low as four milliseconds (ms), and sustained writes of up to 17.2 megabytes-per-second (MBps), according to Taradalsky. MicroNet will deliver the disk arrays in two separate products: RavenProBus, a NuBus board for Quadra, Centris, or Power Macs equipped with a full-length NuBus slot; and Raven ProPDS, (Processor Direct Slot) a card for Quadra or Centris PCs with an 040PDS." Anybody ever use one of these? The card without a HD seems to hang the system when booting into OS 7.6.1 on both a Quadra 950 and a Quadra 800. The card used to be made by Storage Dimensions, MacinStor line (before it was sold to Micronet in 1994) and called either the Data Canon 040 PDS or the Digital Video SpeedArray. There seems to be 3 jumpers on the card that I have no clue about. Thanks for any help. TZ
