I can type things after the @, but it seems that pretty much any
keypress results in a '?' and a new prompt.
I'm a total PDP-11 newb, but the users manual implied that I should be
seeing some sort of post-ish procedure similar to what you get on a
VAX. Any ideas?
What boards are in the system? ?Is the CPU dual or quad height? ?What
board
is the terminal hooked to? ?IIRC, this indicates you're lacking a
bootstrap.
If we know what boards, and drives you have we can probably better advise
you.

This is on a KDJ11-A (dual height). I've just been reading the manual
and yes, as Josh notes, it seems that I'm in the ODT prompt. Do I just
want to try "P" and see what happens?
Right now I have the drives disconnected, but it has the standard dual
5.25" floppy drives and Maxtor XT-2190 (190 MB) drive in it. At the
moment, I have the power supply to the drives disconnected because I
wanted to make sure I could get to a boot prompt sort of thing without
spinning up and spinning down the hard drive all the time--I also
wanted to avoid having it start booting RT-11 while I'm not watching
the console.
Currently the card stack looks like:
[ ? ? dual-height KDJ11-A ? ? ?] [empty] [empty]
[ board connected to serial lines] [empty] [empty]
[ Three connected boards that I believe are ? ? ]
[ ?extra hardware installed by the lab ? ? ? ? ? ? ?]
[ ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ]
[ ? another board
Jerome Fine replies:
My best guess is that you have a BA23 box since you seem to be describing
having two 5 1/4" drives included in your configuration.
Since RT-11 is quite happy to boot with the drives in WRITE ?PROTECT,
I suggest that you attempt to figure out the "sort of" front panel which
allows
that to be done for the RD54 (Maxtor XT-2190). ?If you have a floppy as
well, place a WRITE ?PROTECT tab on it.
If you can also provide the names of the boards, that would be more helpful.
With a KDJ11-A (dual) CPU which does not have an boot ROMs, you may
have a third party controller for the drives with a boot ROM. ?Otherwise, if
you have an RQDX3 (M7555 dual board - required for an RD54) which
does not have a boot ROM and there is no other board with a boot ROM,
you will have to enter the boot program via ODT. ?Since this takes only
about
5 minutes to do, it is not an impossible situation.
Any other question?

Here is a complete list of the boards in my system, as removed from
top to bottom (this was a rack mount unit)
1x M8192
1x M7195
1x mysterious quad-height board from DEC; I can only find labels
saying "PC304135-I4", "0202", and "Rear PSW1-0"
2x Matrox QRGB-G-64/4 boards
1x Matrox QVAF-512/8A (or QVAF-5/2/8A, hard to read)
1x Dataram 40903 (memory? It's got tons of little ICs)
1x M7941
1x M7555
Here are all the boards I have that were *not* installed:
1x M9400
2x M7946
1x TI GPIB11V-1
5x M8045
1x Data Systems Design A44324
2x M8043
1x M8192
1x DT 2766
1x M7195
1x M8059
1x M7270
1x 3com board, all I can find is "QE serial 0223-01". It's dual-height
1x Data Systems Design 804140
1x M9400
4x M8013
1x M7856
2x Matrox QRGB-G-64/4
Hope this helps
