Huh?
I had almost no Problems to install 2.11BSD from a UC07 with tapes written
So my 11/53 just arrived, and my 11/73 is on
it's way, both in BA23 chassis.
Inventory of the 11/53 is:
KDJ11-D/S CPU
Dataram 4093 with 2MB RAM
RQDX3 controller
I've made good progress on the 11/53, and successfully installed
BSD2.11 a MFM drive, by booting from an Emulex UC07 and DLT-8000
SCSI tape drive to perform the install. 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. from simh (and my own convert program for writing tapes
with the blocksizes
2.11BSD want to use) and that on a SCSI Drive connected to a 2nd
UC07.
That are not real single UC07s, that are two on a single PCB, don't know if
that is to be called UC08 at all, but it worked fine. :-)
Make sure the RQDX is the last board in the Card Cage.
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
from "MAP" on the 11/53. If I try to get into F.R.D. with @17772150/...,
it just spits out a question mark, as if nothing is at the address.
Maybe you have a problem with the DIP Switches on the Conteroller?
I have an 11/83 too (which was a 11/73 KDJ11-Bbefore, changed the DCJ11
and the xtal to 18Mhz Versions. No Problem with 2.11 BSD, it runs for
days w/o a single Problem.
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?
No. so far as I know nothing. But..it's almost a year if not more,
since I fiddeled with that stuff.
Just get sure that you have the latest Firmware on the UC07, it can be
found on the net, I you can't find it, contact me, I'll search for it..
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.
It works on a 11/53 wich was some DEC Server CPU before and which I've
polluted with the full amount of memory (1,5MB it was 512K before)
and it worked with my KDJ11-B with 15Mhz and 18Mhz and with and without PMI
RAM.
- 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.

Try to update the UC07 ROM, and if this doesn't help, try another one...
