[no response so far] Update: I have today tried a HP 35470A DAT drive and to my surprise it works. It is a SCSI-2 device like the Tandberg streamer but unlike the Tandberg it works fine. I suspect that they respond a bit differently to SCSI commands. Does anyone know the fix for 386BSD to get the Tandberg working? BTW, both the Tandberg and the HP DAT work fine under OS/2, so it's not a fault in the hardware.
