What Johnny said. The prompt says "(O)", not "(0)" - the letter O for
Octal. The zero after that isn't a default, it simply means that the
value hasn't been set.
There is no default. Or at least no sane one. Zero in this case means
that it's writing to memory address zero for CSR. The diagnostic should
reject that, but diagnostics are notoriously user unfriendly.

From what I observed, this zeroed-out prompt was just
another manifestation
of the zeroes bug. The values were there in memory and were
supposed to be
offered to the user but got blanked out with zeroes instead. I had
suspected this and just hit enter at the prompt and XXDP did, in fact,
exercise the disk. There were blinking lights and head noise, obvious work
being done that wouldn't have, had there actually been real zeroes in the
address and csr fields. I might swap the bad cpu board back in and try
again, but now that the problem has been isolated and removed, I'm inclined
to just enjoy the pdp11 :)

Short question: What did you boot from? The same RL controller and disk
you then wanted to run diagnostics on? Or did you have a second storage,
from which you booted?

Yep, you're right. *sigh* more work. But that's honestly a good chunk
of the fun of this hobby, right? I guess I should take advantage of the
momentum and curiosity about this bug that we have going here. I just need
quite a lot of hand holding because I'm still way too green with this stuff.
Johnny, you're insisting that I put in the real numbers for address and csr
for testing the drive (for instance). I'm going to do that next, here.
But are you understanding that some of us think that the reason it prompts
a zero default is that it's a manifestation of the zero bug and that the
real value *is* actually safe but hidden in memory? Did you see the
RSX-11M crash dump I posted in the other thread?
And to your other query, yes, I'm booting from the rl02 I'm testing with.
I just switch out to a scratch pack once the diag is loaded and ready to
run (hence the warnings about writing on LoaD device).

I didn't see a crash dump, but did you see what I posted yesterday?
The default in XXDP for CSRs is very often zero, and I'm pretty sure it
is so in the RL02 diagnostics (I've ont checked the listing for that
particular one, but I did look at some others that were more readily to
hand). So when it asked you for input and you just hit "return", you
really did tell it zero. Applying the principle of Occam's Razor, and
assuming the simplest solution is the correct one, you got a lot of
zeros back because it was accessing memory instead of the controller you
wanted.
It's hard to believe you have a CPU fault that consistently prints
numbers as zeros yet happily boots three different OSs. Still, I'll
change the tune if you re-run XXDP with sensible inputs.

ok, now with my 'good' 11/34 board set (not the set with the mysterious
zero bug) installed, I re-ran xxdp against the rl02. I'm getting proper
prompts with the address and vectors supplied with non-zero numbers as
defaults. I just hit return like I had been doing with the 'zero-bug' cpu
boards and this time, the tests run, the drive blinks wildly like before,
and I get real results with real numbers filled in. I think this pretty
conclusively proves that there's something really weird (mysterious zero
bug) going on with my other board set.

So, pardon the large post, but here's the real comparison between my
'mysterious zero bug' KD11E-A cpu board M8266, and my good one: First is
the bad. Note that even at power on, I have to halt and restart the
console emulator at 165200. Look at the registers, all blanked to zeroes
and missing digits, too. It did manage to boot xxdp, but when I tried to
enter the correct address and vector to ZRLG??, it actually told me I was
wrong and couldn't even run the test on the device that way. Then I just
accepted the default (which was presented as zeroes) and it did run. Two
passes. Blinking lights and audible head movement. I let it run for two
passes, but it presented even that as zero passes and spit a bunch of
zeroes in the results. Just for kicks, I then booted (and very promptly
crashed) RSX. It crash-dumped, giving a whole lot of zeroes. Next post
will be same test with the good KD11E-A; stay tuned..
thx

CRASH -- CONT WITH SCRATCH MEDIA ON DY0

ok, now with my 'good' 11/34 board set (not
the set with the mysterious
zero bug) installed, I re-ran xxdp against the rl02. I'm getting proper
prompts with the address and vectors supplied with non-zero numbers as
defaults. I just hit return like I had been doing with the 'zero-bug' cpu
boards and this time, the tests run, the drive blinks wildly like before,
and I get real results with real numbers filled in. I think this pretty
conclusively proves that there's something really weird (mysterious zero
bug) going on with my other board set.

Johnny, you're insisting that I put in the
real numbers for address
and csr
for testing the drive (for instance). I'm going to do that next, here.
But are you understanding that some of us think that the reason it
prompts
a zero default is that it's a manifestation of the zero bug and that the
real value *is* actually safe but hidden in memory? Did you see the
RSX-11M crash dump I posted in the other thread?
I didn't see a crash dump, but did you see what I posted yesterday?
is so in the RL02 diagnostics (I've ont
checked the listing for that
particular one, but I did look at some others that were more readily to
hand). So when it asked you for input and you just hit "return", you
really did tell it zero. Applying the principle of Occam's Razor, and
assuming the simplest solution is the correct one, you got a lot of
zeros back because it was accessing memory instead of the controller you
wanted.
It's hard to believe you have a CPU fault that consistently prints
numbers as zeros yet happily boots three different OSs. Still, I'll
change the tune if you re-run XXDP with sensible inputs.
Totally agree with that one.

...and the same routine with the 'good' KD11E-A.
Note that it has proper console emulation numbers with real values and no
missing digits at power on. Also, I don't have to halt the thing and enter
165200 to get it to talk to the console - it does it happily itself. ZRLG??
offers sane defaults and gives real pass counts and numbers in output.
Note also that rsx boots and starts up happily.
What can I say? That other board was just a pretty messed up processor :\
I'd like to fix it, but have no clue where to start.

Have a nice day

!!! oops, I just noticed that I foolishly used wildcards and accidentally
ran NRLGA0.BIC in the former and ZRLGE0.BIC in the latter. In the interest
of being completely thorough, I just re-ran the bad board using ZRLGE0. No
change - the 'mysterious zeroes bug' behaves nearly identically with
both NRLGA0.BIC
and ZRLGE0.BIC on the bad board.

...and the same routine with the 'good'
KD11E-A.
Note that it has proper console emulation numbers with real values and no
missing digits at power on. Also, I don't have to halt the thing and enter
165200 to get it to talk to the console - it does it happily itself. ZRLG??
offers sane defaults and gives real pass counts and numbers in output.
Note also that rsx boots and starts up happily.
What can I say? That other board was just a pretty messed up processor :\
I'd like to fix it, but have no clue where to start.

So, pardon the large post, but here's the
real comparison between my
'mysterious zero bug' KD11E-A cpu board M8266, and my good one: First is
the bad. Note that even at power on, I have to halt and restart the
console emulator at 165200. Look at the registers, all blanked to zeroes
and missing digits, too. It did manage to boot xxdp, but when I tried to
enter the correct address and vector to ZRLG??, it actually told me I was
wrong and couldn't even run the test on the device that way. Then I just
accepted the default (which was presented as zeroes) and it did run. Two
passes. Blinking lights and audible head movement. I let it run for two
passes, but it presented even that as zero passes and spit a bunch of
zeroes in the results. Just for kicks, I then booted (and very promptly
crashed) RSX. It crash-dumped, giving a whole lot of zeroes. Next post
will be same test with the good KD11E-A; stay tuned..

conclusively proves that there's something really weird (mysterious zero

I haven't seen any crash dumps either.

Yeap. Tried that on both boards. It crashes at load on both :(

Seems like running the 11/34 CPU diagnostics would be the next logical

Yep, you're right. *sigh* more work. But that's honestly a good chunk
of the fun of this hobby, right? I guess I should take advantage of the
momentum and curiosity about this bug that we have going here. I just need
quite a lot of hand holding because I'm still way too green with this stuff.
So all other combinations results in different types of strange
behavior. So you might as well start listing what happens with all the
other combos...
Johnny, you're insisting that I put in the real
numbers for address and csr
for testing the drive (for instance). I'm going to do that next, here.
But are you understanding that some of us think that the reason it prompts
a zero default is that it's a manifestation of the zero bug and that the
real value *is* actually safe but hidden in memory? Did you see the
RSX-11M crash dump I posted in the other thread?
I have not yet even understood what the "zero" bug means. :-)
Are you saying that the system works fine, but for some magic reason all
numbers printed out comes out as zero, no matter what number you tried
to print?
What I do remember is that all XXDP tests that I can ever recall running
actually shows, and needs proper CSRs and vectors. And when they show 0,
they use 0. But who knows, I might be remembering wrong, or that
specific test might be the exception. Or any number of possible
explanations. I did check the documentation for the tests, and they also
suggest that the test should show the actual CSR and vector, so the fact
that you get zeroes there are either some really weird magic, or else
the tests are clever and do not give your standard controller numbers
because XXDP booted from that device, and it tries to avoid you
accidentally destroying your diagnostics pack...
And to your other query, yes, I'm booting from the
rl02 I'm testing with.
I just switch out to a scratch pack once the diag is loaded and ready to
run (hence the warnings about writing on LoaD device).
And I wonder if the test might try to be clever and avoid just
defaulting to writing on the diagnostics pack...
By the way. I don't remember if I saw exactly which test your were
running that failed.

What Johnny said. The prompt says "(O)", not "(0)" - the letter O

Octal. The zero after that isn't a default, it simply means that the
value hasn't been set. There is no default. Or at least no sane one. Zero in
this case means
that it's writing to memory address zero for CSR. The diagnostic should

Right. :-)
