I repaired one of these back in '88... for an unlit
LCD screen and an 8088 processor, this was a very
nice laptop.
I'll try to contact my former employer, see what
he might still have... but ISTR it had a brick
supply, negative center...

There's a set on ebay right now and it hasn't been bid on yet so it's still

Noted. In that case I'll desolder the flyback and proceed with the spray
detergent; there's only 2 or 3 pots on there.

Thanks for that; the board's been out of the chassis for over a week now;
I've just been trying to find time to clean it up.
If the flyback is suffering from bad soldering could that itself cause
stress in other components and thus the smoke? It won't take long to
resolder everything since it's not a very big board.....

Hi folks,
Talking about missing AC PSUs does anyone know the power requirements of the
SV328? I got one recently and it's missing it's power.....the socket on the
machine is identical to the TI99/4A, but the TI99 PSU kicks out something
like 8V and 16V instead of the usual 5 and 12.
Anyone got one handy?

That's an excellent starting point; 6 & 14 volts is ringing bells with me,
and there are some caps on the motherboard which could be part of a
regulating circuit. Pinouts match too, I think. I can make sure tonight.

There are no switches at the front of the box, unless you mean the
control panel
which contains the thumbwheel switches and a few other switches?
Do you have documentation on the data buffer board? This one does have 2
switchbanks,
and all are currently 'open'. Those 2 boards are the only one for which
I do not
have any docs.

That sounds more logical to me, but I can only substantiate that when I
have
the memory being available at address 000000.
As a tryout, I'll swap all the other boards in the cpu (I have a
complete spare CPU)
to see if this has some effect as well. I didn't do this before, as the
machine was
in operation until about a year ago, so it is likely to assume that this
could have
worked. I do not know if the MK11 is the original one, or is from
another 11/70.
I'll let you know tomorrow.

No, it's not yet another Gray wall...
I have 2 packages of VMS installation docs,
"VMS Installation and Operations

Order Number AA-LB33A-TE
"VMS Installation and Operations
VAX 6000 Series"
Order Number AA-LB36B-TE
Both are 5-ring insert sets, maybe 20-30 sheets + tabbed divider & end

Anybody want them?
Doc
Thanks everybody for the clear replies.
I removed the bus expansion card (for the external box)
and when I powered up the system again, it just ran fine.
The next step I did was move the RQXD3 to the location
where that bus expansion card was and where the RQDX3
was I inserted a DELQA (M7516). I connected the bulkhead
cable and mounted a 10Base2 transceiver on the AUI connector.
The 10Base2 transceiver has the bare minimum network: just
the T-connector with on both sides 50 Ohms terminators.
The system still boots and runs fine, but I expected to
see the XE: (?) device listed with the $SHOW DEVICES command.
(The system runs Micro/RSX 3.1).
Current config:
slot 1 A/B-C/D : M7554-02 KDJ11, 15 MHz, 1.5 Mb
slot 2 A/B : M3106 4 line EIA MUX
slot 3 A/B : M7546 TQK50
slot 4 A/B : M7516 DELQA
C/D : M7555 RQDX3
all other slots are empty.
Must the system with the new DELQA interface be sys/generated?
Am I doing something wrong?
TIA

Greetings.
I would like to use one of my classic machines to handle all of my email.
Currently, I'm using a Win95 PC. Because it contains classic gear (Voyetra
V-24S 64 port MIDI i/f) as well as brand new stuff (Audiophile 2496 hard
disk recorder), it contains a strange mix of DOS, Win 3.1, Win95, and Win98
drivers. This weirdness is the only way to enable *all* of the stuff in
this box to work together. After four virus attacks in December alone, I
have decided to move my email capability *off* of this box before some
virus catches me off guard. It takes about four hours to wipe and reload
this system and massage all of the drivers until all the hardware is happy;
I would rather avoid this painful task.
So -- how hard would it be for me to handle email on a small, classic
micro? I'd like to use my Z100 running CP/M-86; second choice is my Kaypro
10 (2.2, of course); third choice is the Z100 under ZDOS.
My BellSouth dial-up account does not provide shell accounts, but I see
that there are plenty of free providers out there. Is it possible to get
my classic machine to first connect with my BellSouth dial-up, then log on
to a shell account, and then send mail or retrieve my incoming mail for
offline viewing?
I'd prefer to cobble together some sort of system using other people's
software, but I am a programmer and can write stuff in C or assembler if
need be. Please bear in mind, though, that I have no knowledge of the
internal workings of TCP/IP, Telnet, POP3, etc., and I don't really want to
spend three months learning the protocols and writing and debugging the
code -- but I will if I have to.
Feedback from the list members concerning this idea would be greatly
appreciated.

My typing skills are about the same as yours, and, to complicate things, my

Hi.
I picked up a 35lb load of mostly Mac-related cast-offs last night,
and scored many cool objets de junque.
The 2 things I can't really identify are a Panasonic Easa-Phone,
KX-T1225 which seems to be a speed-dialer of some sort. The other is a
cable with a (Doc ducks & prepares to rub) 36-pin Centronics connector,
plus eyelet ground, on one end and a female card-edge connector on the
other. The shrouds are steel, squared, and embossed "TANDY" on both
ends. While I've never seen one, I'm guessing it's a Tandy printer
cable.
The rest of the haul is mostly OT, but see gimme list below:
working SyQuest 88MB drive & some cartridges
cordless 3-button mouse
a whole bag of the fabled 800K floppies
2 copies of FWB's Hard Disk Toolkit (one is even on-topic, I think.
System 6.0 bootable disk) The newer version came with docs
CharisMac Anubis that I can't date, but there's NO version info in the
docs, copyright is 1989-1996
Astarte Toast CD-ROM Pro v3, in original box but no docs
Adobe PageMill v2.0, no docs no key
Adobe Photo Deluxe no docs
Adobe Illustator v6 no docs no key (Waahhh!!!)
A couple of NuBus ethernet adapters, one with its right-angle adapter
A loose right-angle NuBus adapters with *2* female connectors
several Apple-AUI/10B2 transceivers
14400 (no AC adapter) SupraFax modem (needs 9V AC PSU)
33.6 SupraExpress modem with all its parts
GeoPort Telecom Adapter - first one I've found in the wild
2 28.8 SupraExpress modems, intact
1998 revision of the "Mac Upgrade and Repair Bible" with its CD.
Not bad for free. The transceivers, the 14.4 modem, the Tandy cable
and all the NuBus cards are all up for adoption; the rest is probably
available for trade if you need something.
All this because I gave $35 for a PowerBook 145B I didn't want and the
QuickTake 150 (with all its docs, disks, and a NIB Battery Booster Pack)
that I did want last week. Yee Haw.
Doc
I'm interested in the rc-25's that you have listed. I'm located in Klamath
Falls, Oregon and am willing to pay freight and shipping costs for them. I
have lost a drive head in mine and would like the two that you have for parts.
Please give me a call 1-800-289-2093 regarding this matter.

If you know how to program it, or have some software to do it, you could
clear an area in memory, get it to DMA some data in, and then look at the

That's almost certainly what's wrong. The software probably checks for the
presence of a device at the address(es) it expects for the ADV11; that's
very easy to do (just set up a trap handler in case it causes a bus
timeout, then try to read from the address. If it doesn't cause a trap,
the device is there.)
The standard adresses for an ADV11 are 170400 for the CSR and 170402 for
the Data Buffer Register. The standard addresses for a DRV11 are 167770
for CSR, and 167772 and 167774 for the OUTBUF and INBUF registers.
If you haven't got an ADV11, I can think of three options open to you:
1) get an ADV11
2) get a 3rd party equivalent, such as an ADAC card
3) use some other device, set it to the ADV11 addresses, and hope you
fool the software

Greetings folks;
Someone was kind enough to copy a manual for the Heathkit ET3400
microprocessor trainer for me. NOT complaining, but it was single sided
copy, and I'm anal so I went and copied it from single sided to dual sided 3
hole paper for myself. As a result, I have a single sided copy left over
that is free to anyone that wants it for the cost of mailing.
It is not a 100% complete manual, but the pages that are missing were
skipped intentionally as they were far from essential. I'm a stickler for
that sort of thing and I can assure you the missing pages won't dissapoint
you.
If someone wants it, speak up or the duplicate will probably go into the
trash.
Regards,
Jay West
This is becoming a pretty silly thread because there can be
understanding
without proper grammer ; if we are being technical here. Sure there is
meaning,
u just dont understand it.
The real story here is this is pretty much a none issue since what i
am saying and pretty much what everyone is saying here, is just to enjoy a
hobby. To worry about someones ideas to the point that it bothers u defeats
the purpose of a hobby; to have fun or to enjoy yourself. If you cant
understand something ; it doesnt matter. This is not a business or the F.B.I
; it is just a hobby.
I get your point. I do use a lot of shorthand and because this is a
hobby
i dont focus very much on my grammer. If u see me post then dont read it.
That is all that i have to say about this matter.
joee
P.S i hope the grammer helps you understand this.

If you know its address, try to access the CSR from ODT. For example, if
the CSR is at 772410 (which is the default) then if you type that address
at the ODT prompt, followed by a '/' (without the quotes), you should see
the contents of the CSR. If there's nothing at that address, trying to
read it will cause a bus timeout, and all you'll get is a question mark and
a new prompt.

Probably the Microcomputer and Memories Handbook 1982 is your best bet, as
it covers the 11/23, LSI-11 and 11/2, various memory boards (including your
MSV11-D and MSV11-L), and has sections on the processors, architecture, and
so on. You sometimes see them on EBay. I think that was the last (or
2nd-last) QBus CPU/memory handbook. There are at least one or two earlier
editions that would have the same general infomation, but not the specific
bits about 11/23 and contemporary memory, or 22-bit operation.
There's a companion volume, PDP-11 Microcomputer Interfaces 1983-84, which
you'd find useful. It has all the information about the BA11-M/N/S
backplanes and many peripherals, including your DRV11-B.
Apart from that, have you looked at the Micronotes at
http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/hardwar…
?

Many of the QBus processors have a set of terminators on the CPU card, and
the QBus spec allows for the use of short bus length with light loads and
no extra terminators. The definitions of "short" and "light" are subject
to variation at short notice :-)

This sounds familiar. And to be honest, if you are running anything other
than RT11SJ, you probably have a lot more than 28KW of memory anyway, so
the saving is minimal. My advice would be not to bother trying to squeeze
another 2KW out of the system.

Nope, zmail and MediaMail both see it as multipart but don't see the first
part as the main text part, so they don't show the text straight off, just
a multipart attachment.

I've found info in the micronotes about upgrading a Micro/PDP-11 to use
the KDJ11-A CPU, but I've been unable to find out anything regarding the
new versions of this board. In particular, will a KDJ11-BF drop into
a Micro/PDP-11 that currently has a KDF11B-BH CPU? The box also has a
Clearpoint 1 MB RAM board; any idea of this will work as well?
Any help is appreciated!

i am 38 years old, so there is nothing about my typing style

i collect any computer i can get my hands on.
i am developing an operating system and a multimedia program
to create movies.
i use a newer computer to produce records.
i am also working out, as i was talking about
in the original thread that got off track, a distributed

to do the same.
i guess thats it.

Howdy,
Is there anyone here that would be interested in rescuing an
Astronautics ZS-1, or maybe a couple?
I am currently the Systems Admin for the Astronautics Technology Center
in Madison Wisconsin. Our facility has been sold and our staff may, or
may not, be relocated. Either way, the plan is to scrap the several ZS-1
mini-supercompters that we designed and built here. If I can find
someone who has the resources to pick up these machines, I may be able
to persuade our management to OK it.
Unfortunately, the time window for doing this is very limited. Our
headquarters wants to come dismantle these machines ASAP.
These machines are are large, they require a lot of power, and will
_NOT_ be supported in any way by this company. Each machine is a tall
double-wide rack with a third rack for a Storagetek 9-track tape drive.
If you need more information on what these machines are, or are capable
of, I suggest searching Google. If you have any specific questions,
please feel free to e-mail me.
Later,

I believe all Sequent machines use Dynix. It's all a question of which version you need.
I suppose some of them will run windows nt too, but why waste a perfectly good computer?

I'd like to see how a Sequent that new will handle, say, 16 or 32 cpus. They may very well be capable of it.

Hi, Christopher. Mine is one Sequent Symmetry 2000
with four 486 processors and 256 Mb of memory.
I comes with one extension box with over 10 Gb of
SCSI disks. It uses Dynix like OS.
I'm in treats to get one Sequent Symmetry 5000, with
4 Pentium processors, 1Gb of memory and 10 Gb
of disk.
Both systems can be take with OS, Tapes, Documentation
and so.
The best of all os the possibility to get another one Sequent 5000
same than the other but... with one 65 Gb storage Extension box
of 180 cm high.
Good find if reliable. Don't think so ?

Hi Sergio,
Sequent was/is relatively stingy with information. They are now owned by IBM, who wouldn't even talk to me about my old machine.
That said, the Symmetry series may be the closest thing to a real parallel computer that was ever done with Intel CPUs. They're very cool machines. I don't know the exact models you're seeing.

=============================================================================
1.1 Mailing List Basics
A mailing list is a simple device which takes an e-mail and
redistributes it
to a group of people. People can add and remove themselves from the
distribution list by Subscribing and Unsubscribing. When you send a
message
to the list, it is first examined by the robot for key words that tell
it
to process an automatic funtion (like help, subscribe, unsubscribe,
etc).
If the message does not contain a keyword it is sent to the distribution
list.
1.2 How to Talk to the Robot
There are a few List Processor commands that you might want to use. To
send a command to the list processor, write a message to
listproc(a)u.washington.edu
(Do NOT send the message to classiccmp(a)u.washington.edu). In the body
of
the message (not the subject line, that is) write one of the following
commands, then send the message.
SET CLASSICCMP MAIL ACK
Tells the robot to send you a copy of messages you
write to the list. This is the default.
SET CLASSICCMP MAIL NOACK
Tells the robot NOT to send you a copy of messages
you write to the list. I don't recommend this.
SET CLASSICCMP MAIL DIGEST
Tells the robot to send you a digest of messages
rather than each as it is posted. With this option
you will get a weekly bundle of messages and keep
a nice, tidy in-box.
SUBSCRIBE CLASSICCMP Your.Address
Subscribes you to the list.
UNSUBSCRIBE CLASSICCMP Your.Address
Removes you from the list.
[][][][][][][][][][]
2.1 FTP Basics
FTP is a protocol by which files can be transferred over the internet.
You can use FTP to connect to a remote site and retrieve files. The
commands you use with FTP depend on the software you use. In general
you must make sure that you are in BINARY mode before transferring a
program file or compressed files. The process of downloading a file
is usually termed GET and the process of uploading a file is usually
termed PUT.
Your FTP program will require an address to connect to. For the
ClassicCmp site that address is 140.142.225.27.
You then may be asked to log in (unless your program assumes an
anonymous login). When asked for a name, use anonymous. When asked
for a password enter your internet e-mail address.
[][][][][][][][][][]
3.1 WWW Basics
The only complicated thing with the WWW is knowing what bells
and whistles your web browser supports. You don't really need to
know much other than the address for ClassicCmp. The web site is
all text which means just about any web browser from the oldest
Lynx to the newest Netscape or Microsoft browser should support it.
The ClassicCmp site is http://weber.u.washington.edu/~bcw/ccl.html.

They're called "false cognates." My favorite one in Spanish is "embarazada,"
which would make you very embarrassed if you use it to mean "embarrassed"
(as it means "pregnant.")
There's the story of a female exchange student who told her host family
"Tengo hombre" ("I have a man") when she meant to say "Tengo hambre" ("I'm
hungry"). When informed of her error, she blushed and said "Estoy
embarasada!", which only compounded her chagrin. (She said "I'm pregnant"
instead of "I'm embarrassed.") :-)

OK, I've been watching the thread for a couple of days about battery
damage. I just realized what's confusing me. I'm also fully aware that
I'm about to expose the true depth of my electronic ignorance.
"Never recharge a lithium battery?" (Yes, I've also been watching the
grammar thread.)
My laptop has lithium-ion batteries. That Apple camera came with
"Energizer Hi-Energy Lithium" AA cells that I was planning to stick in
the wall-wart battery charger. I'm fairly certain they're _meant_ to be
rechargeable.
I think I'm missing a crucial concept here. As they say in West
Texas, "Could somebody please 'splain this wonderment to me?"

I heard the advantage to Lithium batteries over Alkaline is that Lithium
provides steady voltage right up until it is dead, where an Alkaline
looses voltage as it dies.
Any truth to that? Or is it simply Lithium provides more amperage at a
given voltage?

In olden days I would go to Radio Shack, but that doesn't work

Anyone know where I could find a small, cheap, low power, amplified,

Rick,
You are correct!
This command set remains one of my all time favorites. I just wonder who was the engineer who developed that command. We had a drum storage device on our 2000 and it spun a bearing one day and made a very loud squealing sound that scared the bejesus out of us. Before it died, I did have the opportunity to sanctify and desicrate several files. If you have any other 2000 tidbits like this one, please post them.
Thanks!

I recharge primary alkalines all the time; roughly doubles their life, although
useful time before they need recharging drops substantially. Can't let them
run down too far though, gotta recharge 'em while there's still life left, sort of

Incidentally, another statement often made which is also incorrect is
'Do not recharge alkaline batteries'. It's intended to apply to the
primary alkaline batteries like Duracells. But, of course, the NiCd (and
other) batteries use an alkaline electrolyte and those are designed to be
recharged.

I certainly don't mean to question your word, but can you provide specific
references?
Material published by William S. Burroughs (references available upon
request) indicate that the problem was that *exactly* the proper amount of
pressure had to be applied to the actuator lever in order to produce a
correct result, which was nearly impossible. The hydraulic piston ensured
that the same force was delivered to the machine no matter how much
pressure was applied (as long as it was enough to depress the lever). This
gave the Burroughs machine a huge advantage over competing products
(several of which existed at the time and all had the same problem), and
allowed it to capture the market.

I just did that and came up with this site
http://www.invent.org/book/book-text/17.html
which contradicts Mr. Lawson's "destructive jam" theory (no offense to John
L.) and supports the ideas I put forth in my previous post.

QNX is a perfect solution for this since it's real-time and has great
interprocess communication built in.
Or, maybe you'd prefer to cook up an OS from scratch.

I think it was Fred in a previous post who said that CompatiCard would indeed do FM, but it's early and I'm too lazy to check right now. :)

Well I gotta say it's great that someone out there is getting a 2000 up and running! I used to work at HP and know a few good hardware guys who might be willing to help you out. Also, if your interested I could ask a few of my old friends to scour their attics and basements for any paper tapes, sleep/hib tapes, or manuals for you...let me know.
Also, I have a trivia question for you...what commands were used to add and remove files from the drum disk drive?

The smaller switch, S1, controls the vector. S1-1 to S1-8 correspond to
bits 9 to 2 of the vector, respectively. ON sets a '1' in the
corresponding bit position. Default is OFF, OFF, OFF, ON, OFF, ON, OFF, ON
= 00010101 which gives a vector of 000124.
The larger switch, S2, controls the base address. The DRV11-B has 5
registers, with factory-standard addresses as follows:
WCR Word Count Register 772410
BAR Bus Address Register 772412
CSR Control and Status Register 772414
IDBR Input Data Buffer Register 772416
ODBR Output Data Buffer Register 772420
Note that the CSR is not the first address.
S2-1 to S2-10 correspond to bits 12 to 3 in the base address. ON sets a
'1' in the corresponding bit position. Bits 15-13 are fixed at '1'.
Default is ON, OFF, ON, OFF, ON, OFF, OFF, OFF, OFF, ON = 1010100001,
which gives 172410 (corresponds to 772410 with 18-bit addressing).

It might work. It might not. The DEC diagnostics make use of specific
facilities in the RLV (QBus) controllers that aren't in the RL (Unibus)
controllers, and may or may not be in a 3rd party device. The early
diagnostics only cover RL01s and RL11/RLV11:
ZRLA?? Controller Test Part 1
ZRLB?? Controller Test Part 2
ZRLC?? Drive Test Part 1
ZRLD?? Drive Test Part 2
ZRLE?? Performance Exerciser
ZRLF?? Compatibility Test
where ?? means any revision (a single letter) and any patch level (single
digit), as usual for XXDP.
The Performance Exerciser would probably work *once the disk is formatted*,
as it just does a lot of read/write/seek tests. The compatibility test is
pointless for a DQ614 as it tests moving packs between drives.
The later diagnostics are for RLO1s or RL02s and RL11/RLV11/RLV12. There's
an extra program to allow you to read and write the Bad Sector Table which
exists on a real RL02:
ZRLG?? Controller Test Part 1
ZRLH?? Controller Test Part 2
ZRLI?? Drive Test Part 1
ZRLJ?? Drive Test Part 2
ZRLK?? Performance Exerciser
ZRLL?? Compatibility Test
ZRLM?? Bad Sector Utility
Finally, there's a pair of diskless tests written specifically to cope with
differences between Unibus and QBus controllers:
VRLA?? Diskless Test 1
VRLB?? Diskless Test 2

I gave the filename to both Jay West and Hans B Pufal
so the files should be available soon and anyone can
grab them. I'm limited to email attachments of 2MB or
less. And even uploading them to my web site took 17
minutes at 145 Kbps.
Actually, I asked about compression and generating
.PDFs for use with other documents I have scanned.
I'm up to my hips in scanned pages from manuals

achh died because of the huge number of posts from people who had bought a
motherboard, case, and video card and wanted help to make it work. We
referred to them as those who belonged on "alt.fix.my.peecee" or similar.
There were some amazing arguments between newcomers, who thought such
lamers should get a polite answer including a solution, and veterans who
argued that doing so reduced the S/N ratio and encouraged even more OT
crap, and that people should read the guidelines. Doubtless some members
of classiccmp will remember Leon Heller. And, yes, that is exactly why the
'bot was employed (it had been tried on achh, but since that wasn't
moderated, it had to be a retro-active cancelbot, rather than an
approvalbot).
As for active, well, yes, I saw the post. And all the others; there must
have been at least ten posts in the last 6 months. Not a very busy group
these days :-(

Thanks for the tip Mike. I had intended to fit some NiCds but opted for two

Luckily the HD is OK. The floppy drive occasionally throws up seek errors
and I haven't been able to clean all of the crud off the head stepper motor.
I've found a source of replacement drives in the UK and at very reasonable
prices.
Cleaned up the mother board with warm water, detergent and a stiff brush,
then let it bake in the oven at 70C for an hour. Had to use a small grinder
and a wire brush on some of the metal work. Installed DOS and I now have
a happy computer :-)

OK. From what you've written there, and a few other places, I assume you

That makes sense. On an M9312, it simulates a power-down and then

Are they M8728-AA or M8728-CA? The latter is only 16KW. The easy way to
tell the difference, if there's no -A or -C beside the number, is that on
etch revision B and higher, the 64KW board is fully populated with 64K
DRAM, while the 16KW is only partly populated. I suspect there might once
have been a fully-populated 16KW version that used 4K DRAMs, though.
I was, no surprise to anyone, wrong about their having switches -- showing
my ignorance about the specifics of 11/70's. Most of the things I've
written are gleaned from the meagre information in one or two of the
processor handbooks, or from my (incomplete) collection of microfiche.
Anyway, the memory box has switches on the front (and I assume you've
checked those?) but as far as I can see from the 'fiche, the memory card
base addresses depend only on their position in the box. So the two cards
have to be adjacent, and nearest the other cards, I think. Do you agree?
It looks as though the box might be set to the wrong address -- 400000 is
131072 decimal, or 128K -- and is only showing 16KW (32KB) of memory. I
don't know how you set the address of the box, though.

> It is the 23-233F1 diag rom.
OK, I've found some data (actually the listing) for that ROM. It's
assembled at 165000 (but it looks like position-independant code, so that's
possibly not its real address). It ends at 165776, ie 1000 bytes (octal)
later. It is indeed an 11/70 diagnostic ROM for the M9312, probably just a
later version than the 23-616F1 my other docs refer to.
The docs say there's no way to enter the diagnostics directly, only by
entering a bootstrap at the "run with diagnostics" address. They suggest
that would be 173006/173206/173406/173606 depending on whether you're
booting from a bootstrap ROM in socket 1, 2, 3 or 4.
The docs also say that when the 11/70 powers up (or you press a boot switch
attached to TP1 and TP2 on the M9312), it loads the PC from address 773024,
and PSW from 773026. And indeed every boot ROM has a reserved word at that
address for the PC, followed by 000340, which is the usual interrupt mask
to set in the PSW for booting. Every ROM has code (opcode SEC) starting at
173x04 leading to a BCC BDIAG at 173020. In every boot ROM, that branch
goes to an absolute jump, JMP @#DIAG, which in turn leads to a PC-relative
jump at absolute address 165564, which goes to 165000 (the actual code is
165564 000167 177210 DIAG: JMP START).
Why do you think address 777644 is the diagnostics ROM start address?
All the 11/70 tests halt on error (unlike the CPU diagnostics for the 11/34
and other processors, which loop on error). The first section tests
assorted instructions that needn't to use memory, the secondary CPU tests
use the stack (R6 set to 000776). However, the very first instructions in
the diagnostics code store registers at 000700...000704, and use 000706 to
hold a flag which tells the code whether it's running on an 11/60 or an
11/70. If the memory isn't working, this will cause problems later in the
diagnostics.
Address 165344 is one of the error halts partway through the secondary CPU
tests (assuming the diag ROM starts at 165000). What it does is set
SP=776, then does a PC-relative JSR to the address 2 ahead of where it is.
The code there checks to see if the top of the stack contains the correct
return address, and should halt at 165326 if it doesn't (it should halt at
165320 if the JSR didn't execute). If it does see the correect return
address, it adjusts the stack contents, does an RTS, ending up at 165342.
At 165342, it pushes a zero and an address on the stack and then tests
RTI. 165344 is the address of the push instruction, and 165350 is the RTI.
That's folowed by a jump to the next test, which is the memory-sizing
routine.
So having it loop until you stop it, and then halt at some address ending
in 344 doesn't make much sense to me. Either you're not starting at a
sensible address, or there's something wrong that is sending it into a
loop. That could be a CPU fault, or maybe (I've not read all the cache
test code) something to do with not having memory between 000700 and
001000.

You probably remember that the rapidly-increasing number of off-topic posts
led to a variety of attempted solutions. That culminated in the creation
of a moderated group, comp.arch.hobbyist. The moderation is done by a
'bot, with human backup, but the group traffic level is very low. I
suspect that's because the 'bot is too good, and it's actually hard to post
as a newcomer, so interest has dropped off. The last few times I tried to
post, my posts bounced, and attempts to contact the human moderators
failed. Maybe I was just unlucky. Anyway, you'll find the FAQ and charter
on Mark Sokos' website, http://home.supernet.com/~sokos/cahfaq.htm although
it's seriously out of date and a lot of the links are broken.

The actual idea was to create or assist with the creation of a completely
"free" (GNU?) implementation of VMS that "looks and feels" just like the
original.
The next step was to port this version of FreeVMS to i386, VAX, and AXP.
I've seen a few projects that have started or have stopped that attempt to
achieve similar goals.

Many thanks for this tagline to a fellow RGVAC'er...
Hello. About the probes with the DILOG DQ614 over one PDP-11/23 PLUS
with one MFM hard disk using the diagnostics program for these board,
I have some matters to speak about:
* Somebody spoke about a possible modification of the U55 chip.
I have the reference of the chip mounted. It's the 55U-91358.
In fact, the order number of some chips of the board is:
25U-91353
69U-91354A
64U-91355
21U-91356
22U-91357
55U-91358
The question is: Could be used some XXDP diagnostic to determine
the possible problem of the board that I told in my previous message
about it ?
* I want to use another hard disk, one IBM MFM full height of 44 Mb.
Is one Type 31 (for the IBM PC) disk. Somebody has the complete
geometry of it ? I don't have it actually available in the BIOS of my PCs,
but I suppose that one 486 or 386 could have it.
Thanks and Greetings

Hmm.. Lots of DEC CPU backplanes have dedicated slots for various things,
and the position/order of the boards is very important. I don't know if
the 11/70 is like that, but I'd not be at all surprised if it were. Have
you checked that everything is in exactly the right place? If you've
removed any optional boards, have you checked in case any jumpers need
replaced?

Do you mean that someone swapped the wires from their normal places, or
that someone added a switch that wouldn't normally be there?

That's an unusual address, and it's only 32K bytes (16KW). You said you
had two 64KW boards. What type are they? They probably have switches to
set their base addresses. Are these set correctly? It would be worth
trying just one, set to address zero, and see if that improves things.
Start with the minimum in the system, and build it up as you get things
working.

It's an odd sort of address. I'd expect it to stop at an address in the
ROM. If you had to halt it manually, it must have been running in a loop.
Why that address, I have no idea, because according to the M9312 manual,
it only runs code from ROM until it has booted some device. According to
the M9312 manual, it runs various CPU instruction tests, then tests memory
>from 1000 to as high as it can go (up to 28KW), then tests the cache. It
will halt if it gets an error in any of the memory or cache tests, but you
can press CONTINUE to ignore the fault and carry on.

All DEC ROM numbers begin 23-<something>. All DEC diagnostic PROM numbers
end in F1. The correct bootstrap for a M9312 in an 11/70 is 23-616F1. If
that's not what you've got, it's unlikely to work correctly.

Well, you ought to set it to the correct value, obviously, but I've no idea
what would happen if you set it too high or too low. Yes, it's the high
limit.

I think the bus init is supposed to set them to zeros. Of course, the map
may be faulty. Normally each memory board has a switch pack to set its
starting address. What type of board(s) do you have?

i think you and i are saying the same thing.
except i am putting more emphasis on the bot being self controlled
with outside help. you are putting more emphasis on remote control
with eventual self-control.
the thing is; the brain is the easiest part. the brain of the bot will
be self learning so each bot will learn as it goes as opposed to me
having to do a lot of designing.
Follow nature for ideas
for example a little child has just enough knowledge to ask about what
he or she doesnt know about.
so each bot will know just enough to refer to the master os on whatever it
doesnt
know until it learns.
it will be set up to sort , retain, recall various information.

Yes, U is the ground for V...Z (K is the ground for L...P). X-U (with all
other bank pins disconnected) gives a start address of 00100000 (32K,
decimal).

If you have any devices in the lower 2KW of the I/O page, you should
disable memory access to that area. If you don't, you'll get a conflict
when both the I/O device and the memory try to respond to the same address.
However, not many small QBus systems have I/O devices in that address
range (160000-167777). It's normal to leave the whole I/O page for I/O
devices, and disable memory in that area, though.

I don't know; try it and see :-) I suspect if you set it to 18-bit mode
and use it in a 22-bit system, it will respond to multiple addresses. If
you set it to 22-bit mode and use it in an 18-bit system with no
termination on the upper 4 lines, it may respond to noise on those lines
and not turn on when it should. The bus signals are active low, so if
there's no signal they should float high and read as zeros -- but life and
bus systems are not always so predictable.
OTOH, if you have a 22-bit processor, it's easy to upgrade the backplane by
soldering four pieces of wire-wrap wire to bus the extra 4 address bits
(and upgrade the BDV11 if necessaary).

Congratulations for your advance. I have one PDP/11-23 PLUS
with 128 Kwords of memory. I don't tried to boot it because
I need to take my own RL02 from Germany where it's actually.
But I use to startup this V6 distribution under Bob Supnik's

some months ago in my private hackings. I should agree to know

Well, I've only been on this list since October, but I think I've gotten a
pretty good feel for the style and flavour in that short time, and all in all
it's a great resource, informative (although, like you, I spend a lot of time
scrolling through the DEC stuff :), and often a lot of fun to read.
Actually Sellam is one of my favourite posters; his comments are usually
quite appropriate and I really appreciate his often acerbic, no BS style; he
apparently values his time (and mine, as the reader), whereas a number
of people on this list apparently have a great deal more time available
than I do (and that's not a criticism; in fact I envy them).
No problem with the 'A' word either, especially when used self-deprecatingly
or as a warning to me that if I say something foolish I might not be treated
with gentle understanding and kindness; I am surprised though, that people as
intelligent as everyone on this list seems to be would not find a more
sophisticated way to show their contempt for someone else's opinions than
to just call them names (and seriously mean it as far as I can tell).
Just my C$.02 worth; as a newbie here I've got no business judging anybody.
But as a newbie, I do want to add something FWIW:
The original replies to Joee made the point that his way of expressing himself
might backfire, in that someone who might have something useful (to Joee) to
contribute might either just skip over his posts or judge that he wasn't 'worthy'
of their help. Then the replies to those replies suggested that if we alienate
Joee we might lose out on something _he_ might have to contribute.
Well, speaking for myself, although I too was mildly annoyed by Joee's style
and _apparent_ attitude, I wasted more time on and was more annoyed by
the subsequent squabbling, although the _serious_ discussions of language
were interesting for the most part. Joee himself must be rolling on the floor
laughing over what he stirred up; reminds me of the story of the person who
was incorrectly diagnosed as retarded for 2 years ("And they called ME retarded!")
I do love the irony that while there's lengthy discussion over whether it's
appropriate to type without caps, there's little interest in whether it's
appropriate to call someone an asshole - style over content, sign of the times...
My point (at last!) is this:
When I first started looking around for a place to find takers for the 30 year
accumulation of hardware, software and documentation I am getting rid of,
this list stood out among the many others as an intelligent and fairly (but
not too) serious and intelligent place; if I'd run across it a few days ago, I would
have passed it by as just another list where people spend more time yakking
and flaming each other than discussing computers and helping each other,
because the people who have relevant things to contribute either remain quiet and
invisible, or their posts are buried among the other stuff.
Maybe, just maybe, there are other people who could make substantial
contributions to this list and vintage computer collecting in general who'd feel
the same way, despair of finding a suitable place to post, and move on or just
toss out their stuff and whatever resources or expertise they may have.
I like your idea of separate lists, in fact I am on a list that does just that;
one list for the actual purpose of the list, and another for OT threads, rambling,
ranting and raving. Works very well for me; I have a choice whether to just
quickly read the important stuff in case there's something urgent to reply
to, or grab a cuppa and 'socialize' for a while.
Oops, this rant's getting longer than even Richard's recent ones; just wanted
to say that while we're certainly going to yak among old friends and ramble OT
occasionally, maybe we should try to stand out among all the other lists and stop
short of the point where someone new with something to contribute will pass
us by and write us off as just another bunch of assholes...

I've got a T3100e, so this may be irrelevant, but FWIW:
Just had to replace the Li battery in mine; cost $15
the last time, $25 today. Since there was just enough
room in there for 2 alkaline AAs in a holder, I thought
I'd give that a try; seems to be working fine so far,
despite being only 3V instead of 3.6V.
Re the HD: when mine failed a few years back, I heard
lots of info that it was an ST-512 drive with a special

As mentioned elsewhere, I'd recommend a cheap pair of computer
speakers as well; trouble is, all the ones I've seen split the batteries
between the two speakers, so it's tough to just use one.
But if you're still looking & don't want to rebuild a portable radio (hard
to find one with a speaker these days), I've got one or two of those RS
powered speakers somewhere that you could have for next to
nothing, depending on shipping cost.

The other piece, with 12 chips per side, is marked:
Front:
PIICEON
SR8192PS
Back:
GTS12 94V0
16 (8 on each side) of the chips are Micron Technology 4C4001JDJ-7.
8 (4 on each side) of the chips are Motorola MCM511000AJ70.
Pictures of both pieces, front and back, are at
http://members.shaw.ca/ajwotherspoon/ps2. Each of the two images is 0.5mb.
Unable to test. Therefore AS IS.
Yours for US$10 (or offer) for the pair plus the shipping cost (Canada Post

Movie studios don't generally make any "puppets" that are THAT big. If it
is entirely anamatronic, then it is probably done on scale. Something of
that size would be limited to basic movements, and probably not for a
movie prop. They would just build dinosaur "parts" (sets and props are
never made to more than what the camera sees anyway).
>Watch the movie Jurassic park #3, the T-rex had his head chewed

>people put in some REALLY big beasts.
But by #3 were these still anamatronic, or entirely CG? (even #1 was a
good chunk CG, but I haven't seen #2 or #3, so I can't give my opinions
on the "look" of it). I would think by the 3rd, the only scenes that
still had "real" dinosaurs would be close ups of the actors interacting
directly with the beast.
However, these kinds of things ARE built for outside of the movie
industry. Ever been to Disney's Animal Kingdom? They have a "Dinosaur
Adventure" ride (or some name to that effect). That has a few "full size"
dinosaurs in it, and they do some basic movements. (Although, if you ever
get to walk the track, I would think you will find they are not truly
life size, but rather use forced perspective to make them look bigger
than they really are). They are probably fairly fragile as far as the
skin is concerned... but I wouldn't want to get caught up in their
skeleton while it is operating... I'm sure it could take a limb off with
ease.

<http://www.mythtech.net>
the idea is to have the robot take care of itself. just refer to the master os
for references and instructions. master os will be used like a server.
server of info, directions, traffic directions , scripts, etc. like a
co-ordinator.
to direct everything that is going on.
for example like a forman on a building site.
the forman gives everyone their job and they go to it.
if there are any questions you refer back to him.
or when you are finished your job, you refer to him
and he gives you another one.
and the forman monitors everything in progress.
if he sees something that isnt going correctly,
he may step in and give other instructions.

Are you sure about that address? According to my M9312 manual

I just think some people need to realize that sometimes, what you get is
the best a person can do. I'm not defending a lack of use of punctuation
or capitalization, or anything like that (re: the emails this thread is
about... I agree they should have had better care taken when being
written)... but with generally poor writing, particularly when you find
the same person doing it over and over... you just have to accept that
that MIGHT be the best they are capable of. And you might want to ease up
a bit on them... since the bitching may very well be taken as a direct
insult to their intelligence level... and is apt not to fix the problem,
but rather cause a nasty conflict.
I mean, how would some of you feel, if you asked about some unknown
classic computer part, and were told "you must be some kind of dumb ass
to not know what that is... anyone who has half a brain in their head
would know this".
But then, if your writing sucks because you are lazy... well, you should
just be taken out and shot... or at least deserve to be insulted for it.
Just my thoughts. And no, I myself have not been insulted by ANYTHING
that has ever been said on this list, much less the recent discussions...
including all the bashing I took over the crescent wrench incident... but
then, I am think skinned (or was that think headed), and it takes far
more than a bunch of emails to offend me (kick me in the nuts... I might
be offended... call me a dumb ass... I am likely to agree with you)

Good question. I'm not sure, I think it's tested by the diagnostics on the
bootstrap card. I think it's possible to disable it but I don't know how.
It may be in one of the processor handbooks, which I can look up tomorrow.
That's where I checked the value for the LSR and USR.

That sounds encouraging. At least it seems to be running the diagnostic
code. I think, though, that the address it halts at is what tells you what
(if anything) failed the test. If you can tell where it halted, it may be
able to look that up.
Do you have the manual for the M9312? There are several ROMs that might be
on it, with different device bootstraps, and I think there are at least two
diagnostics PROM options: one for 11/70 and one for other Unibus machines.
I could be wrong about that, of course; I might be confusing it with the
multiplicity of variants of the M9301. I just happen to have an M9301-YC

Bob is quite right, the exploding battery referred to in an earlier post was
a standard (primary) cell.
Personally I tend to avoid Lithium batteries at all costs, firstly, for the
reasons
given above and secondly, they're probably the least environmentally friendly.
I'm just glad that PC manufacturers use EERAM these days.
BTW, the Toshiba laptop has been thoroughly cleaned and reassembled :-(

Two other things occur to me. The first is that memories like the MSV11-D
(M8044) and MSV11-L (M8059) have jumpers to enable or disable memory that
corresponds to the I/O page. This gets a little complicated... Most DEC
memories decode the BBS7 signal to sense access to the I/O page and disable
memory access accordingly. The MSV11-D has a jumper 1-2 to enable memory
in the lower 2KW of the I/O page for systems that don't use the whole I/O
space; jumper 2-3 (the factory setting) to disable memory in the whole top
4KW. The MSV11-L has a similar arangement, using jumpers 28-29 to enable
the memory in the bottom half of the I/O page, and 27-28 to disable it.

And that's the second thing. The MSV11-L doesn't use BBS7 for everything
it decodes, so you have to set it according to whether it's in a 22-bit
system or an 18-bit system. If there's a jumper from R-T, it's set for a
2MW system. Remove it for 128KW systems.
It's also a parity memory, unlike the MSV11-D, and furthermore it has it's
own on-board parity control and reporting register. I don't think that
would stop it working if not set up, though. If you want to check the
parity jumper settings, the factory default is 9-10 out, 10-11 in, 18-19
out and 19-20 in (to enable parity); 1-2 in and 2-3 out (to enable register
reporting); 6-7 in and 7-8 out (necessary to disable wrong-parity writing
which is used for testing); F-H in and J-H out (to enable the CSR for
parity setting/reporting rather than other methods).
There are also jumpers to enable/disable half the board. Normal settings
are 32-33 out and 33-34 in for a fully-populated board (reverse for
half-populated) and 15-16 in and 16-17 out (the reverse disables the lower
bank, used if part of the bank fails).
Most of the remaining jumpers set the starting address. For a starting
address of zero, you want pins P,N,M,L disconnected, and pins V,W,X,Y,Z
disconnected (the addressing is done in two parts). To change the address
to something other than zero, you would connect one or more of these pins
to pin K (ground).

Quick check is to hold the board with handles at the top/contacts at the
bottom, and look for a metal jumper (W18) about an inch below the handles,
about halfway between them, and above a diode jumpered with a red wire. If
it's there, it's a Rev.A.

I've done it too. A standard BDV11 doesn't terminate the upper 4 address
lines, but there's an ECO (ECO 005?) to fix that. It consists of adding 4
short wires from the contact fingers to termination resistors that are
otherwise unused.

Steve,
Did you use the HP2000 in school? I used to work at a board of education in northern NJ and we used to provide timeshare services to many schools in the area.
Saw some posts back in August that Jay got his 2000 up and running, just wondering if it was available to for a guest to login and reminisce.
Thanks!
Mike
