if you try to get it to boot it says no controller to
every device
except DD and that says no drive
Hmm, I wonder if that's a clue. Ah, probably not: 'DD' means 'TU58',
which is
interfaced through a standard serial line (DL11 clone), and the standard
device location for the TU58's serial line is 776500, which is the standard
address for the first serial line, and since the 11/94 has a bunch of serial
lines, the code probably thinks there's a TU58 there. But there isn't...
I cant get it to go into ODT to look at the registers.
If you look in the "PDP-11/84 System Technical and Reference Manual"
(EK-1184E-TM-001), available here:
http://bitsavers.org/pdf/dec/pdp11/1184/EK-1184E-TM-001_Dec87.pdf
Section 3.7 lists several ways to get into ODT. In addition to those, if you
look at Section 3.2.2, it allows you to configure the machine to fall into
ODT on power-on (section B gives details).
From: Henk Gooijen
The first 4 (5?) slots are QBUS
Technically, PMI, which is more-or-less QBUS on the left (A/B) side (modulo
not having grants, unless the appropriate backplane jumpers are set to send
grants to those slots), and it uses the standard CD interconnect (as in Q/CD
backplanes) on the right (C/D) side to carry PMI.
The RX211 must have the NPR/NPG open. Check the
documention which DIP
switch must be set in the correct position. However, not sure if that
would cause the RX211 to be "invisible".
Right; DMA would not work, but normal master/slave UNIBUS read/write cycles
to the device registers should still work.
Can you check the RX211 in another UNIBUS system? See
whether its CSR
responds.
Another good test would be to plug a known working UNIBUS card into the
11/94, and check if the CPU can 'see' it.
Also, check the configuration of the RX211. It might
be set to a
different CSR ...
Yup.

I hope you tried a TUK50 instead of the RX211, not a TK50 ... (QBUS).
Personally, I would have tried using a simple DL11 or SLU module.
The TUK50 is too rare (read: expensive) to be used as a guinea pig ...

Well actually the the M7547 came with the system. It just says TK50
UNIBUS CONTROLLER.
I took it out because TK50's are very nasty beasts.
The motors do strange things from time to time. Not only that you
can't get the tapes.
The old tapes go sticky and jam. I have junked loads of them

You can of course read and write the CSR and all other registers of the RX211,
*if* it is in the memory space where you expect it. Making sure is easy: check
the jumpers / DIP switches on the RX211.
Note that the RX11 (for RX01 drives) does *not* use DMA, and what's worse
(IIRC) that module does NOT jumper CA1-CB1 on the module itself!
The RX211 does use DMA, so the NPG should be open. As said, there is no
need to cut the NPR/NPG wire, because those two pins go to that first module
at the right side, and has a DIP switch to open / close the NPR/NPG for *all*
UNIBUS slots).
But this is all from memory ... you can read the manual from bitsavers too ;-)
BTW, yes I have an 84 and an 94 in that box (power supply at the right side
of the box). Very similar in all aspects. In fact, DEC did "rebrand" an 84 to
an 94 by swapping the CPU module (and removing the memory modules),
and glueing a label saying PDP-11/94 over the original panel's PDP-11/84.
I have such a box too. Hmmm, should take a picture of that ...

Read the manual. See that setup option K is the Halt on Break option
which has a factory default setting of 0, which ignores console breaks
from the terminal Break key. If you set that option to
1 it enables
the processor to halt if the console SLU detects a break condition
from the Break key on the terminal, which should cause
console ODT
mode to be entered.
