Hello,
I don't usually post here so if I am somehow posting wrong please tell me.
This popped up on the VCF yesterday and I have been talking with the guy
and am going to go pick it up on Sunday, I will be picking up the computer
and the software and hopefully all the manuals too. I am going to a
Hello,
I have this DEC M8017-AA / DLV11 module that I am trying to configure to
act as a console. I have been trying to find a manual to tell me what
jumpers go where, but the only manuals or resources I can seem to scrounge
up are for the DLV11-E, DLV11-F, and DLV11-J.
If anybody knows what the

Hello,
As part of my H11A project, I am trying to debug my M7264-CB LSI-11 CPU
module. When powered on, the CPU does not respond to the Run/Halt switch
either on the front panel or via the console. I found engineering
schematics for the M7264 online, but I was wondering if any in depth
troubleshoo
I was referring to both the ODT prompt and the run light. I get nothing on
the console and the “Run” light does not come on when the switch is toggled.

This is a continuation of my post from about a week and a half ago. The
weekend I had some free time, so I returned, armed with a oscilloscope and
logic analyzer, to try and figure out what is wrong with my H11A. At first,
I tried to use the logic analyzer to confirm that the four clock signals on
Alright, I hooked the oscilloscope up to SRUN off of E68, and found that it
oscillates low at 58.68KHz. This oscillation is very short lived, with it
bouncing back up to high nearly instantly. Hitting the Run/Halt switch does
not have any effect on the period or amplitude of the oscillation.

Ok, small update. My M8043 (DLV11-J) just arrived today. It seemed in good
condition so I confirmed it was set up correctly (9.6k baud and console on
J3), built a serial cable from the information provided on gunkies, and put
it into my system. Sadly, it behaves exactly how it did with the M8017. N

I spent a good amount of time with the RUN LED issue, but eventually hit a
brick wall. I
I took a look at all the lines you mentioned. BDAL3-13, BDIN, BSYNC, and
BBS7 are all active and jump around in some manner. BRPLY is still the only
line that does not have any activity on it. None of the BDAL lines seem
shorted to ground or to each other. My DLV11-J is configured to essentially

Sorry for the break, finals at school have been a little crazy. For
simplicity of testing I have switched back to the M8017-AA instead of the
M8043. The both are behaving in the exact same manner, so I am not ruling
out the idea that the CPU is at fault just yet.

Wow, I wasn't aware that the ODT console needed memory to run. Checking on
my board, it looks like the 4kw was disabled. I plugged in my 32kw module
with my M8017-AA, and it fired right up to ODT without a hassle. Seems that
was the issue all along.

Tried that one out too, and it works. In fact, unlike my M8017, it will

I have been working on it for the past week, and I would say the I have my
system 95% functional as of now.

Hello,
A few weeks ago I ordered a Sigma 400255 for my H11A LSI-11 computer with
the hopes of getting a 8" floppy hooked up for VCFMW. For the most part,
all the tests I ran from the ODT seemed to be AOK. The one this I couldn't
do it boot RT-11 from my TU58 emulator, as it would crash every time.

Man, that its one nice system. If I didn’t already have a S/36, I would be
driving down there as we speak. Maybe one of these days I will get my hands
on a 9 track for the S/36 like the one in the images.
Oh well, good luck to whoever ends up getting the system!

Hello,
I have had this issue with a number of H/Z89s I have. The terminal board
and the logic board are two separate systems, so it seems to be common for
the logic board to go down while the terminal board keeps working. I would
check voltages on the logic board, then take it out of look for blow
