Argh. (Very red face!)
I worked out the trap stack layout by looking at m40.s and trap.c, and
totally forgot about the return PC (that's the 0444) from the call to
trap():
0001740 000013 141756 022050 000013 000000 000000 000000 000034

I clearly should have looked at core(V) in the V6 manual!
The R6 you have recorded is correct for just after the trap; that's
the kernel mode SP, which points to the top of the kernel stack,
in segment 6 (in the swappable per-process kernel area, which runs
>from 140000-1776).
So there is no R5 mystery, I was just confused. Back to the other two!

This theory is contradicted by the fact (mentioned several times, including in
the message you were replying to) that doing a plain 'ls' bombs, but 'sleep
300 &; ls' works fine.

Amusing! Never heard that; our -11's were never under maintenance, so DEC FE's
never worked on them.

It acts just like the original; fails when run by itself, runs OK when 'sleep'
is also running (in the background).

I had suggested to Fritz that the symptoms led me to believe that it was time
to deploy a LA, especially since the MM trap only occurs once between him
typing 'ls' and the process failing - i.e. easy to trigger on.
He offered me the options of look at the IR or at the UNIBUS - I opted for
the IR so we can see _exactly_ what the machine _thinks_ it is doing! No
report back yet, though.
Noel
> From: Jon Elson
> Does the MMU classify what the error condition was
Yes, there are a series of bits in SSR0 to indicate the particular error:
'non-resident', 'length', 'read-only', etc (and also the segment number the
error's from). As my message mentioned, we're seeing the 'length' error bit
on, and for segment 1 (which the instruction isn't using).
> is it possible to borrow an MMU from somebody else?
Fritz does have a spare board, but it has known errors. We haven't thought about
borrowing one yet, it may come to that.
> If this fault could be caused by memory
Well, _some_ of it could. E.g. if the 'jsr r5, csv' is read as 'jsr r4, csv',
dropping the '1' bit in the register number, that would explain the wonky R5
content - R4 does contain the 034 that should be in R5, I have just noticed.
But that doesn't explain the bogus MM trap. Although I suppose there could be
several different problems, all at the same time.

Nope.

Here's a question for someone who has been around long enough to
remember.
Why did none of the available PDP-11 Unixes support the TU-58?
I have looked at Ultrix-11, V7M and BSD 2.11 (didn't try 2.9
but I suspect if it isn't in 2.11 it wasn't in 2.9) and none
of them had support for the TU-58. Seems to me it would have
been a rather simple device to handle as it ran over a serial
line.

Hi
I'm restoring a PDP-8/a with the help of some
friends. The CPU is now passing the MAINDECs I've
thrown at it. The memory is a modern semiconductor
board my friend Anders Sandahl made.
This machine is pieced together from several others
and the limited function panel I got does not match
the backplane I have.
My theory is the DEC simplified the design of the
boardto cut costs and simpler design is not
compatible. Mine is labeled (on the PCB):
"LIMITED FUNCTION BD.
5411507
5011506C-P2"
And the one I need is:
"LIMITED FUNCTION
5411165
5011167"
However, the picture I have of the other is not so
good. I may have read the numbera wrong.
I would very much like to buy one to finish this
project.

Evening folks,
I?m bringing a Sharp MZ80B back to life and have so far fixed a horizontal collapse problem on the video board meaning I can see what it?s prompting for at boot. I remember when I first got this machine back in 2003-ish I dismantled it and discovered some of the tape transport had melted and gummed up the automatic head mechanism.
Fast forward* 15 years and I have the transport in bits again on the bench and I can see that one belt has melted and another is on the way to collapse. Did we ever find a reasonable source of replacement belts? I know a couple of collector friends with 3D printers have printed replacements but this is new tech and I need old tech :)
Cheers!

My PDP 11/40 suddenly lost it's ability to boot RL02 disks except the XXDP
disk. I have two drives, both boot up an XXDP (I have more than one) just
fine, but any formerly-working RT-11 (v 5, 5.1, 5.3) no longer boots, it
just hangs. I have been troubleshooting, running the 11/40 XXDP tests, but
they seem to just hang too. And I am not a big fan of XXDP anyway. I have
cleaned the drive heads, the disks are ok. I can load BASIC just fine from
PDPGUI "tape" through the serial card (M7800)
Any off the cuff suggestions why this specific issue would arise? Power
seems ok, looking for dumb reasons that I missed. I have swapped out CPU
cards, does not make any difference. I am pretty sure it's a UNIBUS
interference issue, at least that's my working theory. I suppose there may
be an RT-11 boot instruction call or routine of the CPU that XXDP does not
exercise explaining why XXDP boots. Maybe RAM locations.
In the end I just have to work through everything, but I am open to
suggestions to help cut down the time spent diagnosing the problem.
Thanks in advance, I will be around tonight (East Coast USA Time)

Random question
would you prefer having, if you had to pick only one, the original PDP
11/70 or the newer "blue cabinets" PDP 11/70, assuming both were complete
configurations with racks of storage etc as they would have been sold, more
or less.
Assume space and power are not issues, consider just the machine itself.

Those reading through the recent "PDP-11/45 RSTS/E boot problem" thread here will know that I've gotten to some corners of my 11/45 CPU now that don't match up with the commonly available engineering drawings.
My /45 is an early serial number (#152). So far I've verified hardware differences on at least my M8100 and M8105 cards and spares, relating to parity error abort handling. I would really like to track down any of the following resources:
- PDP 11/45 system engineering drawings *earlier* than those currently available on bitsavers (Jun '74)
- Any PDP 11/45 backplane wire list (what looks to be a wire list in the currently available engineering drawings is actually only a breakdown of the power harness.)
- PDP 11/45 ECO information, particularly the following:
M8100 00003
M8103 00005
M8105 00005
M8106 00007, 00008, 00012, 00012A
M8110 00008
KB11-A 00015
Bitsavers seems to have a DEC-O-LOG for M8105, but this does not contain specifics on cuts and jumps for ECO 00005, referring only to the associated "kit". DEC-O-LOGs for the other processor boards are missing.
If anybody thinks they might have any of this info squirreled away anywhere, I'd really love to find out more about it!
Parts of the ECO's are pretty easy to figure, just by comparing the state of my existing boards to the '74 drawings. But other parts not so much...
thanks much,

Hi,
I knew that since ~20 yrs, but I didn't know the affected gcc
version(s). According to http://toni.technetium.be/hacker/pragma.htm
this "special" pragma handling should be in gcc 1.34.
But I cannot find gcc 1.34. ftp.gnu.org has gcc-1.30.atari (where the
sequence doesn't exist), and gcc-1.35 (where it's "#if 0"ed).
Does anyone know where to find the source code of gcc 1.34?

My KB11-A prints have an 'overall' date of "4/76" (on the front page), but
prints within the set seem to be older.
E.g. my M8100 prints are dated 2/72, and none contain any entries in the
'Revisions' block (lower left). However, they are marked as Rev. D, which is
newer than the KB11-A prints at Bitsaver, which are marked as Rev. C. So I
have no idea what changed to cause the rev update! (The first drawing, the
board layout, does show a listing for 'D', so maybe it was just a layout
change?)
The boards aren't all the same rev, though: the M8102 in mine are marked Rev.
C.
My KT11-D prints are dated "5/72" (on the front page), and the M8107 prints
are hand-marked as Rev. A, but the M8108 pages have mostly been replaced with
'yellow-sheet' updates with Rev. F, dated 6-'73.

Hi,
I'm looking for some (technical!) information on the HP E2447AA or
E2447AB probe pod (for using a HP logic analyser to monitor a 68000 CPU).
I need to probe a DIP64 packaged 68HC000, but the E2447AA/AB are for PGA
parts. So I figured I'd make a "top hat" PCB to adapt the 68k to a bunch
of HP transition headers.
The E2447AA delays the UDS and LDS signals before passing them to the
analyser. Does anyone know how much of a delay is introduced compared to
the original signal?
Thanks,
Phil.
Kudos to Jesse for working with me offlist, I feel I've gotten a good deal. I appreciate the offers to help purchase, very much, but I got this taken care of directly with Jesse and I'm happy.
We have to understand, as others pointed out, that if no one speaks up for stuff at a price that can keep the parts houses in business then the parts won't be around. By the same token, the parts houses have to know we can't pay typical full price that corporations/military can. We must be willing to pay something above scrap value, of course.
I ask folks to keep an open mind and give Jesse a fair shake moving forward.
Best,

Sorry, but this doesn't really check out. Jesse sent an email to the list,
original subject 'Hewlett-Packard 3000, 9000, Itanium (HP-UX & MPE/iX)

same seller as the original gold scrap ebay link,
https://www.ebay.com/itm/382505855460
Here is the list of reasonable possibilities that I can think of:
- Somebody sent a fake email, from a fake Cypress-Tech.com, and made a fake
ebay page with the sole purpose of defaming this person (I'll admit, not
entirely out of the realm of possibility if there were someone with a
grudge against him)
- Jesse does not maintain full exclusive control over the ebay store, and
one of his coworkers/employees have posted the gold scrap auctions without
his knowledge (I suppose this is possible)

Would it be possible to put it on a disk and boot it from there? If it's in
some documented format (e.g. .LDA), I can easily produce a Unix disk with it
on, if that would help (although loading the image onto the physical pack
would take forever, I guess - although you could let it run overnight).
It's probably not worth trying to devise a way to load individual files onto
a Unix disk over the serial line until Unix is working reliably, so the
program can run under Unix (otherwise a stand-alone program would have to
include file-system code).

One of the first things to add is to store each location's address in it during
a set-up pass, and check to see that it's still there during the checking pass.

Yeah, sounds like you still have memory issues (per the diagnostic grumping).

Starting the CPU (i.e. 'START' switch) or an INIT instruction will clear
the 'trap enable' bit in the MS11-L CSR.
I'd modify your program to set it, and check to see if you're getting
parity error traps. (Clearly, if that hardware - either in the MS11-L,
or the CPU - isn't working you need to look at that first.)
> some of the earlier ones support setting a bit to determine whether
> parity errors will halt or trap the CPU
Huh? I was just looking at parity in the MM11-L and MM11-U (to see if
parity needed to be enabled on them, or if it's always on by default),
and I didn't see that. Also, there's no way I know of, on the UNIBUS,
for anything to halt the CPU (the QBUS has such as line, but not the
UNIBUS). Which memory has this feature?
> I'm curious how OS init code sniffs out what memory CSRs there are,

Unix V6 does nothing at all with parity (doesn't enable it in memory modules,
although the memory that was extant at the time - MM11-S, MM11-U, etc - did
support it as an option).
If one turned it on, the code _would_ catch the trap and 'panic' (print a
message and halt operation). It would be pretty easy to modify the code to
send a signal to the process if it happened in User mode. I'm not sure there's
much to be done if it happens in Kernel mode.
V6 sizes memory by doing a read every 0100 bytes (of the xxxx00 byte), looking
for success or a trap. If that succeeds, it clears the 32. sequential words
starting at that address, and then tries the next 0100. (So if you modified
the code to enable parity traps, you wouldn't hsave to deal with bad parity
left over from random contents at power-on....)

Yup, that's what it looks like to me too..

Well, if you have an M8106, you do have a KB11-A; in the later /45 CPU, the
KB11-D, that has been replaced by the M8119 - but that still has W1! (The
KB11-D prints are in MP00039, 11/55 Vol 1.) I looked on my M8119, and W1 is
indeed there - it's a 0-ohm 'resistor' (single black band) just less than
half-way up the 4th column of chips, with a '1' next to it in the etch. The
M8106 board layout drawing (a couple of pages back from UBCB) does show W1 -
upper left corner of the board, next to E84.

First priority goes to anybody willing to come up here and pick up all or

They are in low-light locations; without flash it's a long exposure and I get
blurring because my hand isn't steady enough. And I don't feel like moving
them, or re-doing the lighting - too many higher priority things to do.

It's spotty, and seems to die out later on. The -11/40 boards have it, but
for the -11/45 and -11/70, some do, and some don't. None of the KDF11 or

Ooops. Fixed. Thanks.

That's the KDJ11-B, no? That's there.

Hey, one just went for more than that: eBait #183624991924, $3K! Admittedly,
that one was loaded, but the page does say "a number of factors will cause
them to vary considerably from the numbers given here ... Exactly which
peripherals and memory are included".
But I did adjust the number a bit - the boards are going for about $50 each,
and add in a BA11-A, it's probably $700 for a bare machine. Actually, I
really need to check all the numbers.
But I think I'd rather get the QBUS boxes sorted out first; I pretty much
only know the BA11's. If someone could tell me what later boxes to list,
above the BA23, (which I also need an image of), that would be very helpful.

Kudos to Jesse for working with me offlist, I feel I've gotten a good deal. I appreciate the offers to help purchase, very much, but I got this taken care of directly with Jesse and I'm happy.
We have to understand, as others pointed out, that if no one speaks up for stuff at a price that can keep the parts houses in business then the parts won't be around. By the same token, the parts houses have to know we can't pay typical full price that corporations/military can. We must be willing to pay something above scrap value, of course.
I ask folks to keep an open mind and give Jesse a fair shake moving forward.
Best,

Holly smokes... 1st, Cindy thanks for calling me and vouching for me on
this list but let me clear something up here....
A. the ebay ads are mine and I put all content up there.
B. there reflects different locations (Largo, Clearwater, Land o lakes)
all around the Tampa area. We have been in that area since about 1995
and address have changed several times because we have moved .
C. The ebay ads are not all corrected with the current address since I
didn't thing that was going to be any kind of issue ever. I have like
400 running ads and you have to individually correct each one.. again, I
really never and up until this moment thought it was ever an issue since
selling on ebay since 1997.
D. some of the older 1k and older board ship from Pittsburgh because
thats where I split my time between Tampa and Pittsburgh and the really
old stuff is in Pittsburgh.
E. I never even posted my ebay stuff on here, I did an intro and posted
some stuff I was looking for.. Heck, I never even contributed to the
ebay thread.

Hello to all IBM 5100 owners,
I have started disassembling and commenting the Executable ROS of the 5100
that a kind soul has exctracted and provided me with the dump.
I've come across an inconsistency with the Maintenance Information Manual
as found on the net. I have both SY31-0405-2 and SY31-0405-3.
The issue is the description of the control I/O commands for device 1
(non-executable ROS selects). The manual says bit 12 is APL select and bit
13 is BASIC/Common select (page C-4), and that matches the block diagram
on page 5-20.
But in fact, the code uses the bits as defined for the 5110 (12=select
BASIC, 13=select APL, 14=select Common) and therefore, the 5100 must be
different from the system described in the MIMs.
So here are two questions:
- Does someone have a newer version of the MIM, i.e. SY31-0405-4 or greater?
A scan would be wonderful, especially because the scans for the
available MIMs are horrible...
- Are there known major revision changes in the 5100 line?
Christian
PS:
I really mean 5100, not 5110 or 5120 ;-)
