Hello, ive been reading on the list here for a while. I'm usually in the
background not seen much, I figured i would give a status update on my pdp
11/34 system. I have been moving quite often for work over the past couple
years, and still have not gotten my machine running since picking it up
over 3 years ago. Thankfully I have all of the equipment and peripherals in
one place now, and am hoping to get this thing finally running soon.
I had picked up an entire truckload of a pdp 11/34 system. Its an 11/34
with a tape drive in a separate rack, 2 rl02 drives and an rl01. Lots of
disk packs and terminals. I fought with some power supply troubles at
first, but after some part swapping i got the machine to power back up. As
of right now, i have a minimal machine that i can key in programs on the
front panel. I was able to enter programs through the front panel that
would display on the vt100 connected via current loop.
Thats pretty much the state of things right now. The system is in a minimal
state,most of the cards are removed for troubleshooting. i wanted to test
the hardware and see if i can boot to a disk packs. My disk packs appear to
be loaded with RSX.
I was trying to switch from current loop to rs232, so i can connect the
machine to a modern computer with a serial port, and dump diagnostics over
the line to test the machine. I have tried wiring up the cable, but am
getting intermittent garbage on the terminal. Thats pretty much the hangup
at the moment. I hope to over the weekend troubleshoot it further and get
this project moving again.
There is a lot of local activity here with all the hacker spaces and
amateur radio folks, i really want to get it running in some kind of public
manner that others can interact with, perhaps some kind of telnet gateway
or over ax.25 packet, but thats later down the line once its running.
There is also another 11 I am picking up in Georgia in the following week,
so i have that drive ahead of me. Not even sure i will get started checking
the other system out till the 34 is running.
Well, thats about it for the state of things and my progress. Once i get
things cleaned up a little better ill post back with some pictures of the
current setup.

About a week ago, "drlegendre" posted looking for some 386 and 486 boards.
I said i had some, but was quickly overwhelmed with work and have not had
time to post back till now.
Should anyone else be interested, I'm putting a link to some pictures of
what 386 and 486 boards i have. Some have corrosion from battery leaking, i
usually clip those off, and use an external battery. If you have a board of
interest in the pictures , let me know and i will clean it up and make sure
it posts / checks out.
I have other boards as well, for pentium, pentium pro, amd k6, 5.25
floppys, drives, etc. Plans are to get a website going with a listing of
everything, but for now, if you are looking for an older system , just let
me know, and ill get back to you with what i have on hand.

In the 1970s I got a catalog from a T-shirt company named "Outer products" and this one was in it. I had to look it up in the OS/360 "Messages and Codes" manual. It's a real code, and it fits. I never did try to reproduce it, though.

Does anyone have any SGI Onyx parts? Any parts. I am trying to resurrect a
deskside r10k onyx, and will need parts - right now I am more focused on
power and VCAM parts, but again, I am interested in all parts.
And if you have a system, I would be interested as well.
This is the original onyx, not the onyx2. I have an issue that is power or
vcam related.
thanks.

Uh, no. The copies there are 'prototypes', later modified for actual use by
adding in the actual address in main memory. Still trying to understand how
that works - the code (in sureg() in main.c) is kind of obscure.

Hi Everyone,
The DiscFerret found a new home.
I did get some questions on its usefulness, which I would address here.
Indeed the software developed for it is limited to a driver and some
analytical tools. But it uses the same format for flux-intervals as the
CatWeasel, at different (higher) clock rates. So any open source
CatWeasel program is easy to adapt to the DiscFerret. Using the provided
MagPie dump program I managed to adapted Tim Mann's cw2dmk program for
the CatWeasel to dfi-files
(https://fjkraan.home.xs4all.nl/comp/divcomp/discferret/). Of course
this only does FM, MFM and variants (DEC and Intel), but demonstrate its
usefulness for archiving.
It is too bad production stopped and the writing image software never
materialized.
BTW, reading floppy disk rate flux-changes can reliably be read with
modern ~100 MHz micro-controller. Several are commercial available.
AFAIK not open source.
Greetings,
Fred Jan

The only -11 that complains if the grant chain is broken that I know of is
the /34 (maybe the /04 too). I certainly have a QBUS chassis right next to my
workstation here that i) has a bunch of empty slots, and ii) works fine, as
long as there are no empty slots between the CPU and the devices.
Also, IIRC he said it works with 3 cards plugged in, but not 4; how can
plugging a card _in_ cause grant problems?

Well, I have decided to stop playing with my hardware for a while and
get back to playing with software. :-)
In order to do this I am building three (maybe four)
PDP-11's. I have an 11/93, an 11/73 and an 11/23+
(and maybe another 11/23 or 11/73). BUt, I have run
into a small problem. Memory. (both the systems and
me!)
My 11/93 has 2 meg internal and I would like to bring
it up to 4 meg. The others I would like to see with
4 meg if possible. (except the last one which I may
deliberately keep at 128KW.)
I have a number of different memory modules. Mostly
DEC but a couple third party. Here's the problem.
None of them are reflected in any of the documentation
I have been able to find so I can't configure them away

Here's a list of numbers:
M7551-AC - All the docs I can find seem to refer to

in the same locations.
M8067-LB
M8067-LF
M8067-LJ - Same problem. I can find no documentation
for any -L boards and these don't even resemble
the pictures I find.
And then I have two non-DEC module that are unlikely to
have any documentation still floating around for.

So, one of the things I have along with my 11/45 is an RK05 alignment
cartridge. Unfortunately, its seems warped -- rides up an down a few
millimeters in each direction as you turn it in an RK05 drive. :-(
Is there any hope for bending one of these platters back more into true
(maybe using a rig like they do with bicycle rims, etc?). Or is it just
basically junk at this point?
I wouldn't really care, but it's an alignment cartridge and there can't
still be too many of these still around out there... So it sort of sux
to just write it off. I'm assuming that if I had to release the media

You've looked in EK-MSV1Q-UG-002, right? That seems to cover a couple of
different revisions.

The M8067-L variants are all MSV11-PL (512-Kbyte QBUS MOS memory). The

I too couldn't find any documentatin for this; there is the 'SMS 1000

Complement. I already have a large stack of empty bezels, acquired to hold
the indicator panels... :-)
Although Dave Bridgham has been playing with the CNC mill at his local
makespace (he's already turned out a bunch of light shields for me), and he
now has a prototype of a thing which combines the bezel and light shield. So
maybe the empty bezels will instead get paired with blank sheets to make a
stack of 1/2-width blank panels. Someone still makes that 'pebbled' sheet
like what DEC used in blank panels, but we haven't acquired any yet to see
just how close a match it is. (Anyone happen to know?)

Wondering if anyone has any EPROM dumps of Netronics' BASIC for the
Explorer/85. I'd like to set up my own EX/85 for that but also have this
little Atlantis 8085 board that I was hoping to experiment with. I've
looked all over the interwebs and have had no luck finding a dump, although
I have found reference to people dumping them for backup purposes.
Many thanks!

Yes and no.... The RK05 alignment pack is mostly to make sure that the fine
lateral track adjustment is correct (i.e. that when the head thinks it's over
track 0, it's _really_ over track 0).
However, there's also rotational alignment (i.e. start of sector), which is
done with the slits in the ring on the pack (so yes, releasing the media from
the hub in an ordinary pack will make that pack unreadable - at least until
it's reformatted). There is an index/sector timing adjustment procedure, and
it uses the alignment pack too, but this rarely needs to be done.
Still, if the platter is on wrong, the whole thing's useless anyway. So as
long as the platter goes back exactly concentric (and I'm unsure of how the
mechanical alignment works, there may be something to assure there's no
runout), it should still be usable for the head alignment. (To use it for
sector alignment, you'd have to ensure that the drive is aligned for this
before-hand, then use it to align the pack.)
But check the RK05 Maintenance Manual (EK-RK5JF-MM-001), and see if there's
anything I missed. There's also an 'RK05 Subsystem Maintence Course' document
(EY-D2055-WB-001) which might contain some useful info.
Off to look at the V6 MMU setup code! ;-)

Anyone here, owning a Xebec Owl and/or its documentation?
The Owl is a SASI-disk-drive from 1984. One could say that it's mostly a
Xebec S1410A mounted on a drive, thus eliminating the ST-506-interface.
The one I had my hands on seems to be a late version, called the Owl II
(20MB instead of 10MB). It shiped with a PC-SASI-controller for the
8-bit-ISA-bus (TTL) and 4KB Boot-ROM (in a 2764-EPROM).
The firmware of the Owl II itself seems to be more advanced and bigger
than that of the well-known Xebec-bridge-boards: The Owl has 16KB
(27128) of firmware, compared to the 4/8KB (2732/64) of a S1410/10A/20.
A lot of its commands are explained in the documentation of the S1420
controller, but it seems there are some commands missing, e.g. the
command 0x0C.
The drive is not compatible with later SCSI equippment. The owner
reported, he did not manage to run it with a "modern" PC-SCSI-Controller
and I'm not surprised about this: Some commands and codes are
incompatible to SCSI/CCS, so the SENSE codes. There is also a command
collision with the INQUIRY command, uhhhh :(
Does someone own the/some/any documentation for the Owl?
It doesn't seem there's much more out there than this brochure:

FWIW, I use a password manager (Keepass/Keepass2, tho there are other

> Re: Microcode, which is a no-go for modern designs
I was a tech in the 90's when the original Pentium FDIV bug was
storming. The issue was confined to the integrated floating point
portion of the processor and was therefore rarely an issue as the vast
majority of software did not use the mathco portion of the chip. Only
a handful of applications and relative handful of users were affected.
This became Intel's position on the matter and they hoped the issue
would just die down to those handful whom they would provide new chips.
The issue did not die down and the bad press forced the decision to
replace ALL pentiums affected. Only a relative few were actually
replaced in the home and small business arena. A software patch was a
common solution to the problem. It masssaged input to the FDIV
instruction to produce a corrected result and worked pretty well as I
recall.
At the time of the storm, the Pentium was still pretty new and very
expensive. Most folks were getting along with AMD k5 and k6
processors. I WAS. I went from k6 to Celeron.

The prices I see for this equipment online are stiff! May I assume (and yes,
I know what that spells) that you guys are looking for machines in the sub
$200 class, not $2000 like some sites have posted? Equipment from the
recycler is so much cheaper, but strictly as-is.

I enjoyed reading the discussion regarding these bogus emails.
I get a one or two per week. Some with no password, and some with a
password only used for one particular site with an email address only
created for that site. (and the site is no longer around more than
likely due to being hacked ... essentially the account I had there was a
throwaway).
Some of the phishers are getting "smarter" and dropping the "-suffix" I
used for the email (which also ends up getting to me ...)
Obviously the system(s) they send it to don't have a camera, don't have
any web browsing software installed, are text based (Linux and OpenVMS)
and I just laugh.
However, I do enjoy totally confusing the scammers. I have the extra
password configured for the SYSTEM account on my main VMS box. The script
kiddies have no idea what to do with a second password prompt (since you
don't get a User Authorization Failure until you enter both passwords,
good, bad, or indifferent).
34630 failures since last successful login
No intrusion records either, as they try once and move on. Long
passwords are looooong so I challenge them to guess. If they get in,
login DCL does checks and if you don't have the secret sauce ... *plonk*
I probably don't have to have extra password set, but I'm paranoid and do
it anyway.
I've also noticed folks at $work are starting to get these "give me
bitcoins because I saw your pr0n" messages as well. Those were some fun
discussions.
