I recently got a PDP-11/34A, with 2 RK05 drives, about 10 packs with RSTS/E and maybe
RSX-11M (not sure about what else). The main cabinet is almost completely full of cards
that I know almost nothing about. I powered up the CPU, and it appears to work. I have a
lot of manuals also. My question is: What should I do first? I have no idea how to clean
this stuff. Right now I really want to know what I should do in preperation for setting
everything up.
Thanks,
Owen

All right. I'll start identifying the boards right now. I spent two months
checking the CPU over before I ever powered it up. I haven't turned on the
drives yet. Where on the internet can I find a site that will help me ID the
cards?
Thanks For All The Help,

All right. I identified all the cards. I don't have any actual DEC
terminals, but I have several that can emulate a VT100 and VT52. I have a
cable that plugs into the PDP-11/34A Data Paths Module (M8265), and ends in
a DB25 connector. How do I hook up a console terminal to run the
console-ODT?
Thanks,
Owen

You don't. The M8265 has no serial port.
You need a DL11, DL11-W or 3rd party equivalent.
The part numbers M7800, M7856 come to mind -- but it's been 15 years
and I'm working from bad memory.

OK. I now have a DB25 connector coming from the M7856 (DL11-W) RS-232 Board.
I can connect it directly to my terminal. Is this all I need to do? If so,
what communications settings should I use?
Thanks,

All right. The following cards are in my system:
(1) M9302 11/04 UNIBUS Terminator
(1) M7257 RK05 Bus Control Module
(1) M7256 RK05 Register Module
(1) M7255 RK05 Disk Control Module
(1) M7254 RK05 Status Control Module
(1) M920 UNIBUS Connector
(2) M7856 RS-232 SLU & Real-Time Clock Option
(1) M7819 8-Line Double Buffered ASYNC EIA With Modem Control
(8) M7847 RAM
(2) M7850 Parity Board For G651
(1) M9202 UNIBUS Connector, Inverted
(1) M9312 Bootstrap Terminator
(1) M7859 Console Interface
(1) M8265 11/34A Data Paths Module
(1) M8266 11/34A Control Module
I have a cable that connects to the connector on the M7856. It ends in a
DB25 connector. I don't have a manual for the DL 11, but the 1973-74 PDP-11
Peripherals Handbook talks about it. So, my question is, how do I attach the
console to the computer, and change the communication settings?
Thanks,
Owen
8:24 a.m.
I just found the manual for the DL-11W. I Found out all the communication
settings, and set up my terminal. I hooked them up with a null modem cable,
and nothing happened. The terminal remained blank, and the RUN light on the
front panel of the computer came on. Should I try the terminal with the
other M7856 card? I'm sorry I'm so dumb when it comes to DEC stuff.
Thanks,
Owen

One other thing that might be a problem. The DIP
switches on the
bootstrap/terminator card (M9301 or M9312 depending on which version you
have) can be set for it either to go into console-ODT (which is what you
I wasn't aware that an 11/34 *has* Console ODT?
Or are you talking about the very non-ODT like "Virtual Console" in
some versions of the M9301 ROMs?

All right. Here's what's happening:
I connected the terminal to the console port.
I turned on the terminal.
I turned on the computer.
The display shows all 0s.
The RUN light is on, and will not go off.
When I press CTRL-HALT, the BUS ERROR light comes on.
When I press CTRL-BOOT, nothing happens.
I checked the settings on the M9312.
Any ideas?
Thanks,
Owen

There are what I assume are grant continuity cards in all the D slots. They
are all secure, and the state of the system has not changed. I haven't
changed the location of any of the cards. Any suggestions?
Thanks,

The grant cards are as they should be. The unit is exactly as it is when I
received it. There are some empty slots, but not any empty D slots. Removing
the terminator worked. I still see nothing on the console. What should I do
now?
Thanks,
Owen

I think I found the problem. According to the processor handbook, the M9301
contains the Console Emulator ROM. My PDP-11/34 doesn't have an M9301. Do
you think that could be it?

The 9312 is a similar (later design) equivalent... Is there one
of those?

Yes. Mine has an M9312. I can halt the system now, but nothing appears on
the terminal screen. Also -- should the RUN light be coming on when I first
turn on the CPU?
Thanks,

Don't you have an M9312 instead? That's a
later version of the M9301
(with a number of electical differences which needn't bother you for the
moment), and it almost always contains the console emulator program.
I thought it was the other way around. I've got an M9301 manual but
no M9312 manual. Almost all M9301 variants have the virtual console,
but unfortunately the M9301-YC (the only variant I have) does not.
AFAIK the M9312 normally has the 23-616F1 diagnostic PROM, which does
not have the virtual console.

Well, the comm settings are dipswitches on the DL11-W serial port/line
clock board.
The cable's a null modem. (The PDP11 doesn't use any flow control on it
so it should be something like this: (BTW -- you may just need to
get 6 and 8 to 20 on the PC side if the PDP11 DL doesn't assert DTR.

Anyone have the DL11-W dip switches.
The console usually runs at 1200 Baud (if it had an LA120), 300 baud
if it was an LA36, or 9600 baud for a Video Terminal like a VT100 or
VT52.
