If the connector on the Orb drive is high density 50 pin, it can't be anything higher than Fast SCSI 2. What you need is an HD50 to DB25 SCSI cable to connect to a Mac, or a NuBus SCSI controller. The two best known are ATTO and FWB Jackhammer. Both companies made a range of SCSI controllers so you need to know which one you're getting. For ye olde SCSI drives you *do not* want a differential SCSI controller, unless it also has support for SE (single ended). There are two types of differential SCSI Low Voltage Differential (LVD) and Differential SCSI, which got "backromymed" as HVD for High Voltage Differential when LVD came along. HVD was short lived because LVD included support for operating in SE mode thus most LVD devices have settings to enable adapting to 50 or 68 pin SE SCSI controllers. FWB made at least one HVD NuBus controller, but you'd only want one if you can lay hands on some dirt cheap HVD hard drives. -- ----- You received this message because you are a member of the Vintage Macs group.
