Blizz 1230 SCSI kit, how i can see thar damn 1230scsi.device?

Is a SCSI device attached to SCSI-IV kit? Perhaps you need to attach a device to it, in order for the 1230scsi.device to show up in the list, in HDToolBox?
Remember that the SCSI-IV kit is actively terminated on one end already, so you just need to use active termination on the other end, after your last SCSI device in the chain.

Another thing to try is to use different memory on the blizzard and the scsi kit.

Last but not least, do not forget to set the memory speed jumper to 70ns (located on B1230-IV card) when SCSI-KIT + SIMM is attached/used with B1230-IV. This is an absolute must, as per Phase 5 manual.
