Yes. All the devices where used in a MVII bevore and are knowen to
work. Thats a bit confusing.

BINGO! Pulling W5 solved the problem. But then I seted it again to
double check. (I changed location today and took only the cards and
disk with me.) In the "new" BA23 the system runs even with the W5
jumper installed. Then I noticed the different setting of the front
panel DIP swich. The upper switch is off and the lower on. The switches
of the other cabinet are both on. If I boot the machine with W5
installed and the upper switch on it hangs. It continues to run
immediately if it is switched off. What is the purpose of this
switches? 

OK. The machine is currently un-tar-ing /usr... :-)))

Ahh, and an other question: Can the RT11 bootstrap listed in 
http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/bootstraps/mscp_rt11.txt
be used to boot 2.11BSD? I have no bootstrap ROM card. (Emanuel, hint,
hint. ;-)  ) So I use a minicom script to load the bootstrap via ODT.
But the current bootstrap script is for TMSCP. So I have to load the
bootblocks from tape...
