FWB made the Jackhammer line of NuBus SCSI cards that supported Wide SCSI. ATTO made the SE-II narrow SCSI, SE-IV with wide and narrow SCSI and the SE-4D that was differential SCSI. AFAIK, nothing newer than Wide or Wide/Differential SCSI was done on a NuBus card. These two have 2x the maximum transfer rate of Fast SCSI 2 because they move 16 bits at a time instead of 8 bits. However, you can still adapt SCSI-3 to Wide SCSI and it will transfer at Wide SCSI speed. Differential SCSI controllers should only be used with Differential drives. You can adapt Low Voltage Differential drives to Single Ended, most LVD drives will automatically sense when connected to an SE bus or they have a jumper to force them to SE mode. There might be adapters to connect SE or LVD drives to a Differential controller, but the cost of the adaptors would make it too expensive. OTOH, adapting an SCA80 SE or SE compatable LVD drive can be done for around $7 for an adaptor with both narrow and wide connectors. I have a Seagate 18.2gig 7200RPM LVD drive jumpered to SE mode on my Radius 81/110 and it works fine. ===== It's total Fandemonium! http://www.fandemonium.org __________________________________ Do you Yahoo!?
