HiDue to the help from Glen Slick. (The only guy to answer the question as asked.)
What to do is interesting. How to do it will get you there.I now have a SCSI drive on the 11/93 that thinks its an RD54 and is trying to boot RSTS/E.
It fails gracefully during the boot giving an error message. So we have a working Hard Drive and Controller on the target system. No to find out what it does not like. The transfer rig is now working OK. So I can try out more drives if needed Rod --
