Fellow techies,
The Byte Shop's owner is preparing to 'unload the archive' of his store in Hayward. This news is based on the attached E-mail I received this afternoon.
Interested parties should contact Michael directly, please. His E-mail address is clearly shown below.
Keep the peace(es).

"If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
I've had a quick look at my 11/45 printset.
It appears that the interrupt handling is partially done by the processor
microcde (page 12 of the microcode flows in my printset). And that there
is no special path for the vector, it's goes via the normal data paths,
into nromal intenral CPU registers, etc.
So, I would propose the following tests :
1) Make sure you can read/write all bits from external memort. Just write
1, 2, 4 ,8, 16,.... to successive locations using the panel and examing
them. Jsut to eliminate a silly fault like a dead data buffer.
2) Run the basic instruction diagnostic if you've not done so already.
This should veryify that the data paths are OK.
3) If possible, try some other interrupting device. An obvious one is the
console receiver. Wirre a program to : Load all the vectors with .+2, HALT
as you did for the line time clock test that's failing.; Read the Console
Rx data register to clear the data received bit (if necessary); then
enable the receiver interrupt; and go into an endless loop. Then you press
a key on the conosle. The processor should halt, but _where_ does it
halt. If 4, then it appears the processor is ignoring all vectors.
Hopefully this will point us in the right direction to look for the fault.

Hi,
I have an HP9000/345 system with two HP-IB interfaces. However I see
that inside there are two SCSI connectors (one with termination resistors
next to a power socket for a disk drive. I also found a reference that
HP shipped 345 systems with an internal SCSI disk drive.
However, my system does not locate a SCSI controller when it boots
(note I am talking about the boot monitor, I have not managed to boot
an OS on this machine). If I remove the ribbon cable connecting the
second HP-IB controller, the machine recognizes a SCSI controller ,
but if I connect anything to one of the SCSI connectors, the system
complains that the SCSI controller registers are bad (failed test).
I believe that there is some config problem (perhaps some jumpers
need to be changed?). Anybody has any suggestions?
Thanks

A few weeks ago I rescued a 6Mhz IBM AT in an unusual rack mount case
with a Plexiglass cover. I don't know how it got in that condition or
how anybody permitted it, being as it was not shielded. But I digress
.. (It is marvellous .. like the original case mod!)
It had a 5154 with it that displayed output, but the output looked as
though it was 'smearing' to the right. This made text look goofy. The
problem was more apparent in graphics modes. A different 5154 or worked
on the machine so it is definitely the monitor, not the EGA card.
I'm a monitor novice. I know these things pack a punch, so I have a
healthy respect for them. Are there any simple checks to make?
(I have the Sams guides for the 5151 and the 5153, but not the 5154 so
I'm kind of in the dark.)
The machine also came with a 5151 that doesn't work at all. I don't
even think it is getting power. For that one I can refer to the Sams guide.
As for the rest of the machine, it was fine except for the full height
hard disk. The hard disk would start spinning, but it sounded as though
it was making metal shavings - I don't think there is any hope for it,
so I replaced it with an modern IDE drive and controller. The machine
has 1152KB, EGA with daughterboard, monochrome card, IBM 5250 emulation
card, IBM token ring card, original BIOS and a single 1.2MB floppy drive.
I want to trace out the bus grant signals on my /45 to make sure there's not
a break somewhere. However, I don't see the backplane printsets on
bitsavers.
I could start at the first unibus slot in the system backplane and check BG4
through BG7. However, I'd rather start at wherever those 4 signals actually
originate. It's pretty hard to identify visually what pins and where, so I
wanted to check the prints. Then I can check from where BG4-7 orignate to
the end of the bus and make sure I have continuity.
Can some one point me in the right direction?

Does anyone know where to find some sound files of the ASR-33 chunking
away on printing something out?
Didn't the teletypes have a bell they rang near the right margin when
printing a long line? Or was that only during input...

This is on an 8085-based system.
It looks as if some of the features of the 8237 DMA controller (like

Right now, there's an 8257 in there.
Other than some reprogramming, is it feasible to make this swap? Are there

I will look at what Byte Paperbacks I have. They are all about
the 6800 (or perhaps more general: Motorola processors). I never
quite liked the Intel stuff, but that is an other topic :-)
I will probably make scans (next week) of the books I find in
the attic (this weekend), so I will post a list.
RA6800ML will be first, but if there is interest for some others,
I will scan them in order of # requests.
As a packratt I will indeed not sell books, except the case where
I have more than one copy. "VAX Architecture" or something like it
comes to mind ...

Every once in a while someone on this list will ask about manuals for
some piece of vintage test equipment that they picked up for working on
their vintage computer.
I was looking for a manual for an HP 6284A power supply and found this
ftp drop on agilent's site:
ftp://ftp.agilent.com/pub/manuals
There was no 6284 manual there, but there was one the 1630 logic
analyzer, and of course lots of other HP equipment.
The web page leading to this ftp site has an impossibly long URL, so I
won't try to quote it, but the page does say:
(quote)
Help us share old manuals! If you have an electronic copy of an old HP
or Agilent manual, we'd like to share it with your test colleagues. Send
a brief email letting us know what you have, and we will contact you
about receiving the file. I have a manual to share (manuals at agilent.com)
(end of quote)
I think it is great that they want to collect the old manuals (too bad
they won't scan them themselves though). If you happen to have any
scanned HP test equipment manuals, why not mail it to them to help build
the archive?
There is also a subdirectory of HP Journals, althoug there are only a
dozen or so issues. I'd imagine they'd post copies of any issues sent
to them as well.

Hi!
Since I had to leave my 8/L behind for the next couple months I got
myself a smaller toy for the meantime. It's a PDP-11/03 with LSI-11/2
CPU, 32k MOS memory and a DLV11-J serial interface card.
It also had an EPROM-board and an unknown interface card (40-pin
connector) by a company called "sprecher + schuh" but I removed those
till I figure out what exactly they do.
Some TU58 tapes came with the machine so I guess the EPROMs only contain
some kind of bootloader and the main program came from the tape. I don't
have the tape drive though.
I made some adapter cables for the DLV11 and can talk to the ODT and
execute small programs. To try something bigger I guess I can use
VTserver. I don't have any tape-images to use with VTserver though. I
found hints on the net saying it is possible to create xxdp and RT-11
tape images using simh or E11 or something like that.
I didn't manage to do that myself though. I can boot both systems on the
emulator but E11 crashes whenever I try to access the emulated DECtape
II and simh doesn't seem to support it at all...
Is there an idiot proof howto somewhere on the net that I missed?
Could someone maybe send me some images to try?
Is this the way to go at all or is there a better alternative to get
software into the PDP?
thanks in advance,
Sebastian
> I have 925 manual(s) and control code info somewhere. I'll try to

This trip into the attic was well worthwhile. I found several things,
include my Yarmish&Yarmish 370 assembler book, and my Baase Vax
assembler book. I also found the old Prime PL/P manual, the MTS
sysprog and operator docs, etc. Cool!
But, for this thread, the useful info is the Esprit 6310 and Televideo
925 manuals. I've scanned these, and they are available as PDF and
zipped TIFFs, at:
http://yagi.h-net.msu.edu/tvi925_ig.pdfhttp://yagi.h-net.msu.edu/tvi925_ig.ziphttp://yagi.h-net.msu.edu/esprit6310.pdfhttp://yagi.h-net.msu.edu/esprit6310.ziphttp://yagi.h-net.msu.edu/esprit6310errata.pdfhttp://yagi.h-net.msu.edu/esprit6310errata.zip
I did the 6310 stuff because the terminal emulated, among other
things, the 925, and the manual has some control code info which
might prove useful. Esprit was the name later used by Hazeltine.
(I suppose they had to escape from the legacy of a name associated
with using a printing character as a control code. :>)
Al Kossow, if you're listening: these are available for your archive
if you want them. They were built using tumble; the TIFF files were
generated using a Canon iR copier and OmniPage Pro 10. (Did I mention
I'm a non-Windows guy? Grrr.) Unfortunately, the combination doesn't
seem to be able to do anything but 300 dpi.
Hope all of this does someone some good.

No, if you have set up the standard trap catcher, and you halt at 4, it
loaded the vector from 0, executed the HALT instruction at 2, and the
PC contains 4 by the time it stops or returns to ODT.

I just had another thought. Standard traps for errors and software
traps start at 4, and zero is reserved. Normal interrupt vectors for
hardware devices use the area from 100 up to 400. 000000 is reserved,
so if anything uses that as a vector, it's because you have some
hardware fault.
My guess would be something along the lines of a hardware device
generating an interrupt, but apparently giving 000000 as a vector
instead of the true value intended. Unlikely all three of your LTCs
would do the same thing. Could be the CPU reading zeros due to a fault
in the interrupt logic, as Tony suggested.

You mean the PC contains 4 when it halts? The LTC interrupt test you
ran sets each of the vectors in low memory to contain two words: when
the processor uses the vector, the first word is loaded into the PC.
The LTC test fills each vector with a pointer to the second word of
the vector, and put a halt instruction in the second word, so the
reason your PC contains 4 when it halts is that it tried to use the
vector at zero. The PC gets loaded with 000002 from location zero, and
the processor executes the HALT instruction at 000002. By the time you
see it, the PC has been autoincrememnted and contains 000004.

Standard stuff. You're supposed to enter _and_execute_ the little
program that fills memory with zeros -- that fills the vectors like the
LTC test. After it's run, the vectors are set up, and *then* you
replace the first instruction, at 001000, with 000777, which is a
branch-to-self instruction. When you run *that* the processor will run
in a tight loop until an interrupt or trap makes it jump through one of
the vectors. If you use the first, shorter program, all the vectors
contain 000000, and 000000 contains a halt instruction, so the
branch-to-self halts at 000000 (so the PC will contain 000002) when it
gets any interrupt or trap.
If you use the second test instead of the first, each vector contains a
pointer to its own second word, so it halts with the PC pointing to
4+the vector it used.

The ISBN is available through the usual suspects - simply lookup at
Amazon, but I wrote I haven't
seen it pop up for used-sale for a while. I also do not expect Henk to
sell it to me, BTW; copies or scans would be perfect for me.

Now, I remember these paperbooks were not too thick (I once had
Emmerichs Tiny Assembler and MONDEB from that class - unfortunately got
lost - TinyAsm at least can be copied from old 1977 Byte issues), so
I'am not sure whether it will wear out more than by simply reading the
book. Unless you have
a multi-page scanner where you'd have to destroy the spine.
Regards
Holger
Correct, I prefer to keep my books in good shape.
But keeping a book on the shelf is not why they are printed.
So, if I can be of help, the book will be *used* instead of
just collecting dust.

I am 100% sure, that I have that book!
Copy or scan is the same work for me :-) The drawback
is that it will damage the glue of the spine ... I like
to keep my books in perfect shape.
There were a few more books from Byte (for the 6800) in
that time. I have the Relocating Linker too.
My first StarShip code was built using these programs!
I also have several books from TSC. BASIC, editor, and
6800 Simulator [ on 6800 :-) ] comes to mind ...
I will try to check this evening (I get home after 22:00).

Hi Jay,
I think I have a set I could loan you, but weren't there two different
models? A "B" and a "C" I think. I don't type well, But I'm willing to give you
phone support on my dime.
Thanks, Paul
I recently saw a thread posted on the parts list for the Radio Shack model
28-280 kit does any one have the manual for it my son would be extremely
appreciative. Allen
We just got a query from a fellow in India who's got a PCB milling machine
connected to a PDP 11/53 running Micro RSX. He's got his data on a Seagate
ST-251.
He wants to convert this setup over to Peecee, migrating the HD data and
running an emulator (he mentions ertz-11).
He's asking for a quote to do this. Anyone want to take this one on? If
so, drop me an email offline. We'd rather not, because of the distance
involved and our unfamiliarity with his setup.
Cheers,
Chuck
Thanks to Richard Cini & Bob Lafleur, everything's been taken care of!
Thanks again, guys!

What do you do when Life gives you lemons,
and you don't *like* lemonade?????????????
Well, I'm working on reworking my PC setup (it's the only accessible EPROM
burner for my old stuff), and I want to set up an MS-DOS (and maybe
Win3.11) bootable partition - prolly on a 256Meg USB key, if my BIOS can
boot from it. That would give me a nice portable environment for burning
EPROMs and the JV CoCo3 emulator w/all my schtuff in one spot.
So, whilst drudging 'round my attic, I came across my original Dos6.22 &
Win3.11 disks - and yes, they're totally original & legal ;-). I promptly
went to make images of them just in case - and my Disk 1 of MS-DOS 6.22 is
hosed. Anyone happen to have an image (rawrite/dd is fine) I could 'borrow'
via email to reformat that floppy? -- (assuming the media's not damaged -
else I'll make a backup floppy and tape it to the original as proof of
legal ownership)
My other 2 MS-DOS & Win3.11 disks read/imaged fine, so if anyone needs to
restore one of their legal copies, I'd be more than happy to provide. ;-)
To my knowledge, the request isn't illegal or out-of-line, but if I am,
please LART me and ignore the request. ;-)
Thanks!

Hi,
This is a LOOONNGG (*very* long!) shot, but does anyone
have any information on Motorola's RGP (I think 1980
timeframe)? I can't seem to find my manual anywhere
(though there are still boxes hidden for me to dig
through -- along with others stored off-site).
Thanks!

I know that these are supposed to be quite common but there don't
seem to be any on eBay at the moment. I'm looking for an old 68k
Macintosh, preferably something like a Quadra 800, to use to run
Macintosh Common Lisp. I used to have a bunch of old Macs but I've
gotten rid of all of them except a Color Classic and I find its
screen too small to use for Lisp development. Anyone have a Quadra
800 with a 14/15" color monitor they want to get rid of? I would
prefer one with an internal CD-ROM drive. Other Macs (maybe the
LC475) might be okay too but I'd like one with a 68040 processor.
Thanks,

Hi,
for historical reasons I am looking for an electronic copy of the
RA6800ML relocating assembler for the Motorola 6800 (surely one can find
and even write from scratch PC-based crossassemblers, and I do know of
several of them, but this is not interesting for me).
This was published by Byte Paperbooks in 1978, and its ISBN is still
listed at Amazon et al, but hasn't appeared for quite some time as a
used book. I have located the corresponding relocating linker (at least
it seems to be it) from Flex Usergroup downloads (where it is listed as
"unidentified/RA6800ML") but this linker is likely the code from another
Byte paperbook of that time. Or if someone has this book and could xerox
it for me, provided we can negotiate some method to transfer expenses -
I'd be willing to pay reasonably.
THX & Regards
Holger
I have some early DRAM chips, was wondering if any of you guys would be
interested? It's gonna take me some digging to get to where they are, so I
figure I'd ask first before doing that. :-)
If there's some interest I'll dig 'em out and post a list.

This subject comes up from time to time, and I ran across the following post to
the Heath Listserver that applies equally to classic computers. He makes some
very good points, and I too am becoming more and more aware of things that
should be done to preserve some of the less common stuff that I have.
**************
I've been following the recent thread on Boat Anchors regarding large
collections of ham radio equipment and the (eventual) problem of
disposing of them after the collector's eventual (and inevitable, I
might add) demise and exit from this world.
I, too, have accumulated my share of old radio's - both amateur radio
types and broadcast types. When I was younger, I frankly did not give
much thought to what a burden these might be to my family when I pass
away. But now I am older (just retired and a 'youngish' 65) and I have
certainly given the problem much more thought. Additionally I have
helped other's dispose of their collections and have, in some cases,
purchased collections of equipment for my own collection. Anyways here
are some serious thoughts for those of us who love our radio's.
1. Make a list of your radio's and keep it up to date. Include an
estimate of condition and what you would guesstimate the 'street value'
is. Make sure your wife and family know where this list is.
2. Make a list of people and organizations your wife and family can
turn to for help when the time comes to dispose of your equipment. In my
case, this includes a few local hams and the antique radio club that I
belong to.
3. Keep your collection honed down! Purge it on a regular basis. EBAY
and these lists are a great way to keep the surplus down I'm still
working on that part of it and, more or less constantly, I go though my
'stuff' (not just ham or radio gear either) and get it gone!
4. Buy with discrimination! It is easy to become a hoarder! I am
trying to be more discriminating now - in fact, I skipped the last
couple of hamfests. I only buy what really appeals to me and only at a
good 'value point'. I have plenty and plenty of radio's to work on. I do
enjoy the hunt for new and interesting radios (building an HBR is still
a dream) but I am more discriminating that before. Plus I try to sell
some for every one I buy (kind of spread the joy).
So it is serious - this 'obsession' that we have. It does behove us to
try to keep it in check and try to make things easier for your spouse
and your family when the big cleanup is needed. With any luck, I'll sell
my last radio just before you pass on and that will be one less burden
for my wife to cope with. Meanwhile I intent to have some fun with my
collection. But remember - the emphasis should be on the fun (and in
preserving old radios!).

I just used this company to get Patrick's Megatek "Whizzer" graphics
terminal (1984) to my house in Salt Lake from Dallas. (Sweet unit
by the way!)
I selected their "cardboard crate" option and they prepared everything
for shipment and contracted with a freight carrier to have it
delivered to my house. (There was also a RSTS distribution on magtape
combined with this, thanks Patrick!) They did a very professional job
of wrapping and cushioning everything in the crate and it was
delivered in a timely manner with no damage.
Their home page <http://www.cratersandfreighters.com> has a photo
gallery of the various crates that they've built for items they've
shipped. The company history says that they started in Silicon Valley
in 1990 and that they specialize in the shipping of electronics, art
and antiques.
I would recommend anyone needing freight shipping to check them out.
They work directly with dovebid and govliquidation and are familiar
with those sorts of auction lots.

The 11/45 will boot xxdp+ v1, but won't boot RT11 v5.1.
Upon booting the RT11 v5.1 RL02 pack, the disk flashes for about 5-8
seconds, then the processor just halts.
First question which I didn't see in the RT11 5x docs... what exactly would
the hardware requirements be for RT11 5.1 on a 11/45? Is it expecting a
minimum of memory? Certain I/O devices at certain locations? I tried both a
real DEC RT11 v5.1 RL02 dist. pack, and also was able to gen one from a 5.1
image on a scratch pack with vtserver.
The only thing I can think of (and another listmember point to as well) is a
problem with interrupts. But I've no idea how exactly to go about
troubleshooting it, not being a DEC expert like others here :) I've gone
back and forth between using 8K core, 16K core, or 128k unibus memory.
Similar results. My copy of xxdp+ seems a bit old, so most diags I have seem
to have older names.
Any thoughts are most appreciated!

I just have a question about Standby mode on an 11/34. I read it's
supposed to leave power applied to MOS, but do the fans and whatnot turn
off along with the CPU? Or are they supposed to stay on? My junk's in
a BA11-K box.
the manual for my T Personal Mini calls for a T 925 or
950 for the console. Floppies (bad) have emulator
software that makes a pc look like one of those. So
does anyone know of another way of emulating a T
terminal, or perhaps got one theyll let go cheapish?
This all assumes the hard drive even works, but what
have I got to lose.

Hello all;
I have been offered an RS/6000 Powerstation 370. Not sure of whats
in it yet... can anyone shed some light on this system? Is it a
decent machine for running latest AIX versions?
Thanks
David Barnes
davebarnes AT adelphia DOT net
OpenVMS , Tru64 , Solaris , Linux , OS X , SGI Irix
Had this machine dropped on me last night...
Can anyone tell me anything about it?
So far, google etc. have turned up little.
It's a "squat" format workstation or server of some
kind: 11"w x 18"d x 21"h
Front bears the name: UNISYS A SERIES
Two doors reveal:
Upper: Tape drive, CD-ROM, Floppy
Lower: Power/Drive lights and key switch
Two serial number labels on the back, a smaller
one which says:
Style: A7-311
And a larger one which says:
Style: CER4344-100
One of labels inside says it was made in 1994.
Appears to be somewhat "PC-ish":
- Large maniboard with EISA slots
- CPU card with 486 CPU and "OVerdrive socket"
- VGA connector on back
- PS/2 Keyboard and Mouse connectors
- Also has serial, parallel, SCSI and UPS
connectors.
It also has a very large network card, and another
card with more RAM and several large UniSys chips
that I don't recognize (one with a large metal lid
with the warning "DO NOT PRESS ON LID" printed
on it!).
It powers up, but reports that it's configuration is bad,
and that I should run the setup disk. All I can do is
press F1 to try and boot the floppy.
Doesn't appear to be a PC - attempt to boot a DOS
floppy results in silence (machine sucks on it for a
while, then goes into la-la land).
Attempt to boot a cleaning disk results in the message
"Disk read error" and return to the "Press F1" prompt.
(which suggests that it didn't have trouble reading the
DOS disk).
Can anyone tell me exactly what this is? What does it
run? Any information would be appreciated.
Regards,
Dave

I remember flying all over the US with my toolkit. Then once at LAX, United said
no and I had to check my toolkit. The toolkit was broken when I arrived at the
next stop and my luggage was sent to the wrong city.
After I got back, I raised hell at the United office, and never flew with them
again until many many years after I had left that job. Still makes me irritated
when I think about it including the nonsense with TSA. I *REALLY* dislike stupid
people!

I don't know that area, or if it is close to Walnut Creek.
The installation instructions detail how to install the magnets and wiring onto
a Selectric. Volume II contains the illustrations of the Selectric that go with
the installation instructions.
When I go back over (hopefully tomorrow), I'll check and see if any Selectrics
survived the dumpster.

The advanced cases show signs of renting and borrowing space to hold
equipment that won't fit into their own property. I've seen where once
the cellar and living room and dining room are filled (and the wife has
left the marriage) they go on to spending all free money on rental sheds
and even warehouse space. The truly sick go on to form museums so they
can write off their expenses on their income tax.
Again, from (my) memory :-)
If core is installed, the standby position is of no use.
To use the backup battery the 4th "power brick" is an H775 (IIRC)
which is needed for the battery charging/regulation.
If you have core in the machine, the 4th power brick in the power
supply (H765?), is the H754 for core (+20V and -5V).

Hello!
I'm looking to trade my two MM11-DP memory modules for a 128kw(256kb)
module of MOS memory. (Preferably MS11-LD)
Anyone who is interested in the MM11-DP modules let me know, I may be
convinced to sell them if the price is right.
Julian
Uhhmm, there *is* a standby LED on the front panel, it is
called BATT. You will see "something" of this LED only when
a battery is installed in the system. Here are the LED states:
OFF : battery voltage is below the minimum level required to
maintain the contents of the MOS memory, or the battery
is not present in the system (probably your situation)
FLASH SLOW : (once per 2 seconds) battery is charging and the
voltage is above the required level to maintain the
contents of th MOS memory if power is removed
FLASH FAST : (ten times per second) primary power is lost and
the battery is discharging while maintaining MOS memory
contents
ON : battery is present and fully charged.
- Henk.

Okay, it's just that I was testing the switch position just to see what it
did, and everything went off including the front panel. I guess it's
supposed to do that.
I don't know why DEC didn't put a standby LED on the front - you'd think
because it's already powering the MOS, you wouldn't care about powering some
silly LED.
What does that position do if core is installed?

My list of chemical exposure is huge, and includes automotive chemicals
and paints, industrial chemicals, commercial cleaners and degreasers,
and smart-but-stoopid kid exposures (smart enough to experiment, didn't
know about the risks). I do have a serious genetic disease that will
result in a short lifespan. I don't know if its from my life exposure or
exposure to a toxic dumpsite that my mother lived next to as a child
(hexavelent chromium and other stuff in Woburn, MA). Out of 4 kids I'm
the only one with the disease, so it could be from my technochemical
exposures.
I also have technology-hoarding disorders that I struggle with daily ;-)
in all likelihood Intel is far too simplistic an
answer (although I do recall seeing pictures of
multibus type boxes with an Intel monniker, so things
like that could possibly qualify). I suppose even a
sbc could qualify, or even some sort of add-on for an
established system. But sdks from Intel (or others)
dont. Seattle Gazelle? What about 80186 firsts? 80286?
I know the popular conception is that Compaq built the
first 386 desktop, but I seem to recall ALR being
numero uno (pretty sure it was ALR).

this week), but I know I definitely have them (its in the graphics
databook as well which I certainly have), so when I have the time, I'll
put them online...

I have not found any interest on the net in this equipment, so
hopefully it might be worth something to someone if offered for free,
otherwise it may be destined for the dump when I have to move.
AT&T Unix PC (Internal HD, boots to prompt)
Vector Graphic Memorite w/ manual
Original IBM PC & Printer (both in zip up carry bags)
I certainly wouldn't turn down a small donation for anything here,
but I'd rather see it go to a good home than get pitched. I can't
afford to move everything I have with me off to school!
Thanks,
Chris
It's been a long time I had the switch at the Standby position.
*IIRC*, everything goes OFF, and only MOS memory is powered, but
there are a few wires on the backplane, where the power leads
are soldered, that connect the backup supply pins to the main
supply pins. To use the memory battery backup, you must remove
these wires, but without a battery and the charger plus a cable
to the BA11 power supply, it is useless.

Curt,
Do you still have the ATR8000 co-power-88 software and docs?
Let me know, I will have some free time this summer and I would like to lay out a new co-power-88 PCB and make it available to all those interested.

Speaking of inscrutable error codes from IBM BIOS, in the big
equipment purge of 2006 at work I obtained a number of IBM PC model
350 and 365s. In my various disassembling and re-assembling of pieces
amongst these systems to make a smaller number of maximally configured
systems I occasionally get an inscrutable error code form the BIOS.
Does anyone know if there are manuals for these models online? I
tried searching IBM's web site, but immediately got lost in the
large amount of irrelevant results.
--
What errors? I am familiar with those models. Fairly standard PC, nothing
unusual about them. You're looking for the HHM for these computers, but their
website has changed a lot since I worked there. DId you try
_www.pc.ibm.com/support_ (http://www.pc.ibm.com/support) ? You might also want to look around
at service.boulder.ibm.com too.
Does anyone have a .dsk image of an RL02 with a later version of XXDP v2?
Hopefully that matches more closely the diagnostic manual on bitsavers?
Thanks in advance!

That is the INMOS G170 graphics chip. Used in the IBM graphics cards.
I got the datasheet somewhere in my house :-)
I remember AD also made a pin-compatible version of it too...

I don't know where in the overall timeline this is but wasn't the Tandy 2000
based on the 80186? It was introduced in 11/83 and ran an OEM version of DOS

I think the distinction for 8086 may be Altos or one of the other S-100
makers, although Intel may have had a card for the MDS even before that.
Bill Godbout had his 85-88 card considerably before the PC.
As for the 80186/80286, we were debugging pre-release engineering samples
of both chips at Durango (I still remember the bug where DMA activity
would clobber the DI register). For sure, the 80186 Poppy rolled out very
early. I don't think any 80286 versions were delivered until the Xenix
port got finished. But there was a socket on the board for one before
that--just nothing to run on it.
By the time of the 386, Mobo profiles had pretty much standardized for PCs,
so I suspect someone like Mylex may have had the first motherboard, but I
don't know if that counts as a "computer". The PS/2 386 boxes were also
out fairly early--didn't the Model 50 have a bug that required replacement
of the mobo?

Hi,

But, having a helluva time trying to sort out

I managed to get things running on an AV3000

For those who don't already know, I focus my vintage
collection on Ohio Scientific.
I would really like to fill out my collection with a
C1P-MF Series II, pictured here (sorry if the URL wraps):
http://www.technology.niagarac.on.ca/people/mcsele/images/OSIAd-1981PopularE
lec.jpg
Also, I need the tan/brown metal floppy chassis for an
original C1P-MF. Yes, I know that many were sold with
the metal/wood floppy unit that usually went with the C4P
but I'd like an example of the other model.
Finally, I'd like a better example of a C4P metal/wood CPU
chassis. I have a 4P with the electronics in good shape
but the case is pretty rough.
None of the above need to be working, just in good physical
shape.
In pursuit of the above, I am considering trades of other
parts of my collection that are rather rare. Also, I have a
small reserve of convenient, wallet sized presidential
portraits (but don't get any ideas of ebay level riches).
Thanks,
Bill Sudbrink

How about this: Dig in the KW11-P manual if its available and see if there
is any info on replacing a KW11-L with it. Maybe that will tell you where
that LTC L signal is.
Given that the system seems to pass a lot of diags, but fails the LTC test,
I'm focusing there. From looking in the programming manual for the DL11-W,
it appears that bit 7 never being set means that there is no LTC L signal
coming in to the DL11-W. It would appear that software clears this bit and
then waits for it to set (by the square wave from the AC at 50 or 60 hz or
so). According to the diag, bit 7 never sets, so I'm thinking I'm not
getting any LTC signal from the power supply. I need to find that square
wave signal and see if it's working and directed to the right place.
My problem is finding that signal. My 11/45 is a KB11-A, serial number <
2000. The maintenance manual shows the LTC coming from the power supply to
the power distribution board (top connector towards the cabinet door) shows
six wires, the bottom one (brown) going to slot 1 row C where the M787
option plugs in. My top connector does not have that many wires, only 3 or
so. My system never had (I don't believe) a M787 card. The system came with
two DL11-A (M7800), and a M7228 (KW11-P). But I don't think there was ever a
LTC in slot 1. So is it possible that LTC isn't even routed out of the power
supply? I'm wanting to use a single DL11-W with the onboard LTC. But doesn't
that need to get the LTC signal from the backplane? If it wasn't ever routed
to the system unit....
So I'm not sure where to look. I'll pour over the manuals some more.

Actually, what I meant was EXAM errors. I can DEP but not EXAM.
However, this is sort of amusing, because what I'm basically doing is
entering an address, and depositing a value into /dev/null.
This could very well mean there's nothing wrong with any of my equipment,
and once my MOS memory arrives, the problem might clear itself up.
Thanks again, Don.

Oh CRAP. I built this machine from parts (albeit all marked 11/34), and did
NOT know that I needed an H754 for core. Would this couse the deposit
errors I'm experiencing?

Since I've had a number of requests for the picture, it is online at:
http://www.rain.org/~marvin/escon.jpg
Included, but not shown, are two manuals. The first has the installation and
instruction manuals including schematics, while the second contains the
illustrations and diagrams for use with the Vol I instruction manual. There are
also a number of what look to be Selectric parts.
>From the information in the installtion manual:
"The ESCON equipment covered by these instructions fits all IBM office type
Selectrics. The length of the platen or if it is single or dual pitch, has no
affect on installation of this system. If your machine has a manual velocity
control, contact the factory for special instructions."
Another interesting quote from the instruction manual:
"the magnets used in the ESCON conversion kits have 55-ohm coils, except for the
shift magnet which has a 130-ohm coil."
There were no magnets in this package. I suspect if there was a Selectric
already prepared with the magnets, it got dumpstered before I got a chance to
check this stuff out.

Hello michael,
I am in NZ. and looking at buying an old ATC 510 which is for sale. I am a retired airline pilot and am helping a young guy next door to get his licences.
Is the 510 useful for basic instrument training, or would I be better off using a microsoft sim? What accessories have you got and where are you?
Many thanks

Actually DEC took a lot of care over diagnostics. All systems were
sold with comprehensive relevant diagnostic media, normally accompanied
by the listings. In the early days the listings were on paper, but
later on microfiche. Furthermore, DEC maintained those diagnostics
carefully, and there were regular revisions and patches when necessary
which were sent out to customers who had maintainance contracts. I
don't know about the paper listings, but microfiche was certainly sent
out (inserting the updates used to be one of my jobs). In fact,
there's the problem -- when you do find listings, which have often been
separated from the machine and media they originally were meant to be
with, they may be for a different revision or patch level. The code
will be close, and the listings may be useful, but may not be quite the
same. Paper listings in particular will usually be for older versions
of the diagnostics, and many diags came along late enough that the
listings were only on microfiche.
A full set of PDP-11 microfiche diagnostics listings, such as might
have been held by a Field Service office, reseller, or a third party
maintainer, is one whole microfiche box, some 14" deep. There would
normally be another box beside that with the hardware documentation:
manuals, engineering drawings, parts lists, illustrated parts
breakdown, field and engineering change orders, etc.

I don't know that DEC ever distributed soft
copies of diagnostic listings on disk or tape (now finding that would be
the holy grail at this point).
-
I've never seen them either. If there is ever a HP vault trip, that
would
be something to look for.
Paper copies of the diags stopped when the maint fiche doc sets came out
This is probably what the diag handbook was based on.
If there are specific diags needed, I'll scan them from fiche. It is a
fairly long process to get clean copies, since the scanner is a
fiddle-fest
to set up at high magnifications.
For what's it worth ... I do not have an 11/45 :-(, but I
was triggered when I read M787. Long ago, I added "LTC" to
my 11/35, which involved installing an M787 in slot 3,
position F. The 11/35 manual said that you must cut one
wire on the backplane ... perhaps that applies here too ...?

As I stated in the chat last night, I don't know a whole lot about 11/45s
(or rather, any PDP11s before the /04 in general) but I would recommend
downloading xxdp v2.5 and seeing if that even boots. This is an easy way to
figure out if (a) it's just RT-11 5.1, and (b) if there are additional diags
on the xxdp 2.5 cartridge that might help nail down the problem.
Downloadable here:

I hope that helps.

I have a couple of Zenith power supplies, fit their models 151, I think,
maybe more. Anybody interested in taking these off my hands?

I've got an Escon Microcomputer/Selectric Interface System that looks
like it was sold as a kit. It appears to be a unit to convert a
Selectric I or II typewriter so it can be used as a computer printer. Is
anyone familiar with this unit, and any ideas about what it is worth? It
belongs to the widow of my friend who died last month, and I am trying
to help separate the good stuff from everything else.
Okay, so I was thinking, would it be possible to replace the regulators and
whatnot in a BA11 with several standard PC power supplies? Obviously there
would be adjustments that need to be made, but considering the DEC units are
now 20+ years old and the out-of-service modules may have dried up caps,
would this not be a possible option?
I'm just curious, I'm no electrician, nor have I looked over the leads yet.
Secondly, if I have less than half the BA11 box full of cards, do I need
both of the fans plugged in?

I pretty much counted on this being the answer, and again it was more of a

As these are pretty much the only sort of B machine that started with
the
B 5000 that normal folks are likely to run into, there is going to be
some
interest in the future.
I think it would be *FAR* better to contact the owner first. From what
I've seen, the connection is slow and there is a lot of material there.
It is also possible the site could be mirrored on a faster connection;
after all, the guy is a ham and thus a good guy :).

BTW, this site has been posted both here and on the Heath Listserver. It
is entirely possible that a number of people are hogging the bandwidth
and copying the site. If so, that kind of misuse could well result in
the site going down. Look at the notice on bitsavers!

Umm, thanks but no thanks, it was a technical curiousity, not indicating
anything was broken.

"BA11" covers a lot of chassis/backplane combinations, both Q-bus and
Unibus and not really any bus. I suspect you're talking about the 10.5"
high Unibus box. Dried up caps in the modules are far from a fundamental
difficulty. Compare that with re-doing the power bussing on the
backplanes
and replacing a couple of caps seems downright easy :-).
Not all the backplane signals are drop-in compatible with PC-clone power
supplies, but when third-party manufacturers used PC-clone power
supplies
for Q-bus chassis the extra signals were easily generated with a little
board.
On the Unibus, you probably need at least a token 15V supply and maybe
one that can give substantial currents (depending on what boards you've
got.) Some of those will run off +12V just fine, but others won't
Look at Strobe Data's Unibus backplane for an example of one way to
approach the problem: http://www.strobedata.com/home/ubus.pdf
One warning: few "350W" PC clone power supplies are actually capable of
pumping out half that much power. There are good PC-clone supplies but
at
that price point the "industrial" switchers are not too far off in price
(and are
far more flexible in terms of configuration.)
