my pdp11/53 and pdp11/73

Ideally I'd like to get the OS on a SCSI hard drive, but I'm having trouble getting BSD2.11 to recognize the UC07 as a second MSCP disk controller, which would be the easiest way at this point. I'm not having much luck with my 11/73, which turned out to be an 11/83, for which I also now have a spare 11/83 and 11/73-B CPU. In my 11/83 system, "MAP" shows the address the MSCP or TMSCP address the UC07 is jumpered for, but nothing (blank line) under "Device Type" for that address, no "DU" or "MU" description like it just spits out a question mark, as if nothing is at the address. Do I have to do something in SETUP mode an 11/73B or 11/83 CPU to make it "see" MSCP controllers at specific addresses? Should it be reporting a DU or MU Device Type in MAP, instead of blank lines? Right now my CPUs are set to the "Initialize the Setup table" defaults. - Several different CPUs behave the same way. - I assume there might be a correlation between the problem with F.R.D. and the fact the device isn't showing up like on the 11/53 in MAP, but I don't really know since I've never seen it work right on an 11/83. - I've tried this in two different Q-BUS BA23 chassis. Same results. - I'm having similar results with other kinds of MSCP controllers with the 11/83 CPUs. I haven't gotten anywhere with them either. Mark -- Mark G. Thomas (Mark at Misty.com)
