Hi folks,
I've been chatting to someone who has a TRS80 Model 4 that's giving him a
horizontal sync issue, is there anyone around the Fremont area who could
give him a hand with it?
Cheers

I just got off the phone with Jesse at Cypress. He said he did not post the
gold and tantalum items on ebay. It is someone else, trying to cast a bad
name on him.
I explained to him that the list would really like to work with him, and
that old HP stuff is wanted. He explained that each item is put into a
system, fully tested, and has warranty and follow up support if needed, so
prices are not low. I explained to him that many list members can do board
level repairs.
I suggested a "garage sale" type scenario, where he offers as-is equip, to
save the costs of paying a tech to test everything. He is open to that idea.
He has pallets of old terminals and keyboards that he does not work on
anymore, so no warranty. I told him that if he would test the monitor to
make sure it turns on, and include a complete matching keyboard, members
would prob pay about $85 plus shipping for a set. He does have a 150, and a
lot of 1970s and 80s terminals and keyboards. He said he will gather them
together and do a basic test and offer some out, on an as-is basis.
Please understand that he is a business (for the past 30 years), and he does
have to cover costs of storage, technicians, etc. No, he won't sell stuff
for $5. It costs him more than that to pay someone to find the stuff and
pack it. Please bear his needs in mind too.

I've always wanted a 3000 system to play with after using one (as a user
only) many years and many jobs ago.
Epay prices seem a little high. $current_job had one years ago and sold
it on eBay for $250 (I found the sold listing in a folder ...). I cried
a little. It wasn't a fill the floor model - but it had to have had a
little "oomph" as it supported 30-40 interactive users all day.
I agree with the other posters and the list-boss - if you provide hobbyist
pricing I'd be game. You're not going to get far with commercial or
"high price just because it's rare but not in demand" pricing.
Otherwise, I offer fifty bucks ... :)

Man you guys are tough... We sell this old HP stuff, thats what we do.
There is no commercial or retail price in 20+ year old items. Its comes
down to what we have into it, what others are selling them for, and what
the demand is. Jay, I dont recall quoting you a 12920, I went back 3
years on my sent emails and I cant find it. I dont remember what the
price or circumstances were. If I had that info, I could understand and
explain the price that I quoted you .. but I'm glad you found what you
needed... sorry if you were offended.
As for me posting an intro on this site.. I have a boat load of older HP
stuff and I'm always trying to find homes for. If my info or parts helps
someone get the part or system they need, then its a win for everyone.
I'm not some spam bot that just sends crap email out, we are a very
small company thats been around for 25 years and we have a lot of
knowledge with this older 1000, 3000, 9000, & Itanium hardware.
Resellers get flack from everyone but small HP vendors like us help keep
the wheels of this older HP machine rolling. Try to buy a 25 year old

So this really confused me, as the UNIBUS spec says parity is wholly within
the slave device, and only an _error_ signal is transferred over the
bus. E.g. from the 'pdp11 peripherals handbook', 1975 edition (pg. 5-8): "PA
and PB are generated by a slave ... [it] negates PA and asserts PB to indicate
a parity error ... both negated indicates no parity error. [other
combinations] are conditions reserved for future use."
The answer is that originally the UNIBUS parity operation was _different_, and
that sometime around the introduction of the PDP-11/45, they _changed_ it, which
is apparently why Appendix E, about parity in the /45, says what it does!
I found the first clue in the MM11-F Core Memory Manual (DEC-11-HMFA-D - which
is not online, in fact no MM11-F stuff is online, I'll have to scan it all and
send it to Al); I was looking in that to see if the parity version had a CSR
or not (to reply to Paul Koning), and on the subject of parity it said this:
"The data bits on the bus are called BUS DPB0 and BUS DPB1." And there is
nothing else on how the two parity bits are _used_ - the clear implication is
that the memory just _stores_ them, and hands them to someone else (the
master) over the bus, for actual use.
Looking further, I found proof in the "unibus interface manual" - and
moreover, the details differ between the first (DEC-11-HIAA-D) and second
(DEC-11-HIAB-D) editions (both of which differ from the above)!
In the first, Table 2-1 has these entries for PA and PB: "Parity Available -
PA ... Indicates paritied data" and "Parity Bit - PB ... Transmits parity
bit"; at the bottom of page 2-4 we find "PA indicates that the data being
transferred is to use parity, and PB transmits the parity bit. Neither line
is used by the KA11 processor."
(Which explains why, when, after reading about parity in the MM11-F manual,
I went looking for parity stuff in the KA11 which would use it, I couldn't
find it!)
In the second, Table 2-1 has these entries for PA and PB: "Parity Bit Low - PA
... Transmits parity bit, low byte" and "Parity Bit High - PB ... Transmits
parity bit, high byte"; at the top of page 2-5 we find wholly different text
>from the above, including "These lines are used by the MP11 Parity Option in
conjunction with parity memories such as the MM11-FP."
I looked online for more about the MP11, but could find nothing. I wonder if
any were made?
This later version seems to agree with that Appendix E. I tried to find an
early -11/45 system manual, to see if it originally shipped with MM11-F's,
but couldn't locate one - does anyone have one? The ones online (e.g.
EK-1145-OP-001) are much later.
It's also interesting to speculate about _why_ these changes were made; I can
think of several! :-)

Bummer time.... I turned on my VXT2000+ today and after about
5 minutes there was a "pop" and a small puff of smoke from
the power supply. No smell like you get from a selenium diode

twitches and the led blinks slowly. No obvious blown part
visible. Does anyone have a service manual for the H7109-B

I can't remember the video output on the Rainbow, but I wanted to do
something similar to have one setup for the S-100 machines. After
looking on eBay (before I banned them from my use), I found a device
that basically had RCA audio/video inputs with a VGA output. It also had
the advantage of having an analog TV tuner built in so I could also use
things like the old video games that had the Channel 3/4 output.
The device is buried somewhere so I can't tell you the brand.

Excellent! I imagine you're busy with a soldering iron at this moment? :-)
Once those are fixed, it will be interesting to see if the problems you saw
with the OS's go away.
It'd be easy to hack V6 to turn on parity error detection, if you'd like to.

I don't know about 4116's, but I've seen a fairly high failure rate on _some_
cards with 256K DRAM's - on one board, a couple of chips totally dead, some
others with just _some_ bad bits. Other cards were totally fine. I suspect it
depends on the chip manufacturer.

Ah... Looking at the "pdp-11/45 processsor handbook", 1972 and 1973 editions,
there's an "Appendix E: Memory Parity" (of which I was previously unaware!),
referred to in "2.5.6 Memory Parity". (I haven't checked to see if later ones
have it.) It claims there are "16 memory status registers ... each one
associated with an 8K section of memory". (It doesn't say whether UNIBUS
memory, Fastbus, or both!)
One bit in each register claims to be 'Halt Enable': "[when] set, the machine
will execute a halt if a parity error occurs"; when clear, it traps to 4!
Even better, it claims to be able to control whether the memory uses odd or
even parity! (How, for UNIBUS memory, I don't know - there's no way to do
this over the UNIBUS. And the MM11-L and MM11-U manuals indicate they both
use odd parity, although there's a CSR bit to allow wriring 'wrong' - i.e.
even - parity.)
Very odd. Maybe this was deleted in the hardware (or they decided not to do
it), and someone forgot to follow through in the manual? I recently found
another reference to a /45 CPU feature I'd never heard of - forget what it
was, alas!

Could be. I wonder if there's any way to get ahold of the ECO list for that
card?

That's odd; those are the 'error address' bits. Maybe there's an assumption
that the sweep of memory to size it will have caused a parity error from
garbage in DRAM at startup? (If so, I wonder if it would work on a machine
with all core? :-)

Oooh, pretty clever - good workaround for rhe undefined relationship between
CSR's and memory.
If I added parity support to V6, I'd be tempted to do it with a
hand-configured table - devices are all manually configured anyway in V6, so
I'd be continuing a theme... :-)

Hi All --
Thought you folks might be interested -- I've been working on a Xerox
Star emulator at LCM+L on and off over the past year and I've finally
unleashed it upon the world.? It's called Darkstar, it's open source and
it runs all the Star software I'm aware of.? The Ethernet interface is
still mostly untested, however.
You can grab the emulator and its source code on our GitHub site
here:https://github.com/livingcomputermuseum/Darkstar.? Disk images are
available on Bitsavers as always.? Thanks to Al for providing a lot of
assistance on this project.
Please let me know if you have any questions or suggestions.

This is not quite last call, but it is getting close ...
We have 16 exhibits so far and we need a few more to make the show work.
(20 would be nice, 25 would be ideal.) The event is March 23-24th in
Seattle. Soon I'm going to start working on the exhibit floor plan, set
the event schedule, and start to do the prep work that makes the show
possible. But I need to know who is participating before I get too deep
into that.
If you know you are definitely going to participate then please help me out
and formally register. If you have questions or are on the fence then let
me know and I'll try to help you decide. Maybe this is not the right year
for you, and that's fine ... but if there is something I can help you with
let me know.
I'm not fussy but if you can exhibit Commodore 8 bitters or Amiga equipment
then I really want to talk to you. :-) (We seem to have a gap in the show
there. Amazingly, nobody is doing an IBM PC related exhibit either.)
A description of the event can be found at http://vcfed.org/vcf-pnw .

Is it really an MS11-P? Those are EUB memories; I don't recall offhand if

Hi folks,
I'm in search of source code for AT&T's System V Release 3.2.1, 3.2.2,
and/or 3.2.3 for the 3B2. Does this exist? Has anyone ever seen it?
Note that I'm not looking for the System V Release 3.2 Source Code
Provision for the 3B2 /310 and /400 -- I already have that. It was
absolutely invaluable when I was writing my 3B2/400 emulator.
The reason I'm so keen on getting access is that I have ROM images from
a 3B2/1000, and I'd like to add support for it to my 3B2 emulator. The
system board memory map seems a bit different than the /300, /310, and
/400. These max out at SVR 3.2.
I can't imagine trying to add 3B2/1000 support without the 3.2.x source
code.
I imagine there's some tape image somewhere that's a delta of files that
take you from 3.2 to 3.2.1, 3.2.2 or 3.2.3?

Hi - I am making some room. I have a two SGI Indigos. One of them is a R4K.
The second may be a r3k, but may be a r4k as well (I wont get a chance to
check til the evening).
Both will have ram/cpu/graphics/sled. If youre local, come and get them.
If no takers locally, I will ship for cost of shipping (but I wont get a
real chance to do this for a week or 2, if not longer).
Ping me if youre interested, thanks.
I have used Jorgs kit to get my 11/70 front panel running.
There is NO NEED to split the cables - for manual circuit, nor is there in the new
?cap? adaptor board.
I *THINK* Jorg has many cables and many panels and the split is a throwback
to some earlier work that I saw photos of.
My (wire wrapped, no using the new ?cape?) is at http://www.scotnet.co.uk/iain/DEC/1170/ <http://www.scotnet.co.uk/iain/DEC/1170/>
Flat 40 pins - no split.
I have not had time to document the process of the old or new board. All I can say is
that the kit turned a messy job into a fairly quick and easy one.
I can strongly recommend the kit to anyone.
It took me two nights with the circuit list and a wire-wrap tool to set up the board in the
link above.
Then an elasped day footering with the test software and scope checking signals etc.
With the newer 11/70 add on board I would think it would be a painless evening of work.

Greetings CCtalk,
? Does anyone in the Boston area know of a working 80-column
punched-card reader?
? I'm working with a researcher at Harvard who's come across some very
interesting election polling data from the 1960 Kennedy-Nixon race,
punched onto about 10,000 cards (five boxes).? That's too many for
manual transcription, but too few for an industrial-strength solution.
? The cards are in a professionally-managed university archive, so it's
not as easy as just throwing them in a shipping box and sending them off
to who-knows-where to be read.
? Some of the cards are in binary format, so I'm fine with some ad-hoc
Pythonic data massaging, if I can just get the bits read.
? If anyone in the Boston area has a machine they might be able to make
available, could you get in touch?
? That's fedorkow at mit.edu
? Thanks!

This doesn't seem to have been done because you needed to re-order them (they
turn back into flat cables before they go into the connectors - although
perhaps you cross-connected a pair of wires)? Easier access to individual
signals for debugging?
Needless to say, if people who want to build one of these also have to do

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.
