Hello Al, I have an interface like this, and an attached working hard disk that boots RT11. I don't have an original floppy disk with drivers or tools, I'm searching for it too, but some time ago I did a copy of the hard disk content, thus also of the drivers for the interface. I'll be glad to send / upload an RT11 floppy image for SIMH including these files. Furthermore a guy an year ago contacted me about drivers for SMS (I posted a message searching for manuals at the time); he had a copy of manuals and ROM onboard with latest version. I can provide a copy of all of this. Let me know how I can send you the files. Andrea
