Hi All
The Last UA auction, I picked up about 9-10 old IBMXT/and clones
upgraded 5150 ?. I don't collect any 8088 machines, I simply wanted
these for the MFM drives/cables. Most of the machines had been lying
around for ages in somebody's dusty wherehouse and some were missing
power supplies, etc, so I made no attempt to resucitate any of them
before canabalizing.
After taking them apart. I have all these parts for the taking. Just pay
the postage. I would prefer someone to take the whole lot. Any items
left unclaimed goes to the dump.
I can check any of the cards or boards for certain chips or info If you
need me to.
So here is what I have:

I have Xenix running on the Nabu 1600. This is an 8086 processor with 512k
or RAM, four serial TTYs, and a custom MMU board which provides memory
protection and management features Xenix will NOT run with the MMU board
removed. Early QNX however does run without the MMU (as does CP/M-86 and
MS-DOS) - QNX is one of the smallest somewhat *nix like OS's that I've
seen run on a bare 8086.

Dave

Hello All,
I am in the process of scrapping out my Telecom gear. I have some LA 120's and other Dec boards that I will be listing. The printers are not very economical to ship, so my thoughts are that there may be some interest in the parts. If that is the case, please let me know.
A year or so ago, the folks next door talked about wanting to sell their Dec inventory, test fixtures and prints. Although I did forward all of the info to them, I don't think they did anything with the information. If there is still any interest, please let me know.
Thank you.

Hi
I might have a manual someplace that has it in it. It
was a single chip combination of a number of 2901's in one
package. I think it had a 2910 as well. I forget if it
was 4 or 16 2901's. Still, basically an extension of the
2900 bitslice family.
It will be some time before I can dig into my piles to find
a book on it. Anyway, it was still considered part of
the bitslice family and not a uP.

Looking for some DEC stuff for my private collection... New Mexico, Texas,
Arizona area preferably:
Any BA23 chassis (these could probably be shipped)
Actually, BA123/213 would work too
Any H9642 racks
Any SDI drives (RAxx)
Any working RD54s
9-track tape drive--any make that can be connected to a VAX,
i.e. Kennedy would work, though a TU80/TU81/TU81+ would be
ideal, as I already have the controller.
KDA50 disk controller
Any of the following: DELQA/DEQNA, RQDX3, TQK50
Contact me off-list if you have any leads.

I suspect that it might be very well be a corruption of the story
about Randy Cook's easter egg in TRS-DOS, that showed up in NewDOS
prior to NEWDOS80. That one really DID exist. RS, in TRS-DOS 2.3,
changed "Randy Cook" in the easter egg to "Tandy Corp". It was
invoked by running a boot file as if it were a program, with one
of the master paswords, and pressing 'J'? and 'N'? while it was loading.

That's funny, because the first time I heard the story a few years back, it
was a lawsuit between AT&T and SCO over the rights to unix. (Or was it
MicroSoft and Xenix...???) Should this discussion be moved to the urban

Little bit of a problem with that logic...you would want to "accumulate" or "sum" the light from shorter exposures to simulate a longer one, not "average". And if the light is low enough you could end up summing a bunch of "0"'s in any case....
OK, at a mere OCT 20 years I think I'm the youngest on the list - I
started out playing around with NIBBLES.BAS on my dad's business 286
Vectra laptop (he worked in Shipping at HP), I can't really remember
when, but I was young - around three years old. When dad got his 486, I
played extravagant amounts of Commander Keen 4. Started writing tiny
programs in the library at school on the 386 there when I turned 7.
I have fond memories of lending my dad's HP95LX and playing with it,
especially after he got his 100LX. The 95LX was confiscated by my school
and subsequently lost by the teacher, and the 100LX was broken by my
baby stepbrother who tripped over the charger... and gave me two
HP50LX'es...
Had a fascination with 1980s computers like the Commodore 64, sat in the
basement typing BASIC games off the "Learn BASIC" book when I was around
10-11. I think I was about 12 when a friend of my mom's lent me a
machine with Visual BASIC - and I did some very... BASIC stuff with that
too, but rapidly started getting a hold of things
At age 14 I sort-of got a job setting up Windows XP machines for a local
gaming place, where I met Bj?rn Vermo, investor, cctech mainframe guru
and list member, and his girlfriend, Debbie, who told me about the
Informatics library and the books there. I managed to navigate my way
there, and was shocked to find a PDP-7 in the atrium. I did not know
much about big iron back then, so it was a great opportunity to learn a
lot more. And learn I did - I subscribed to this list (first cctech
digest, then cctech, then the full cctalk - addictive :), started
getting into Linux, learning to code a Real Language, learning about
electronics, and classic computing, etc. I found it remarkable how much
one learns when one completely ignores school!
Now I just recently got my very own PDP-11, which I with the help of
gordonjcp over IRC fixed :)
My dream job is working at a museum, maybe even starting a separate
computer museum (which Norway, with a very interesting computer history,
IMHO really needs, but that's another thread :)
Hell, I'd be a building super if they let me use a 360/91 as the
furnace :)

Does anyone else on the list collect mousepads? If so, what is the size of
your collection and do you specialize? I was just looking over some the
oddballs I have in my own collection which is over 600 pads (with a number
of dups. included) and still growing. I collect all types such as those put
out by computer companies, business of all types, pads with liquid/floaters
inside of them, really oddball ones like the mousepad telephone sold by
Sharper Image, odd shapes, and ones that are true artwork done by real
artist (on commission) and children that are cancer patients. JohnK
Very cool. Got it working. It's a clever device that sits between
the terminal and computer. It simply bidirectionally and
transparently passes characters terminal <--> computer, but can
pattern-match text from the computer and send text to the computer
in response.

Isn't technology wonderful?
I now have FORTRAN IV actually working now. I did previously make
FORTRAN IV "HELLO, WORLD" run, using the TYPE command, since I had
troubles with FORMAT, but it turns out the troubles successfully
using FORMAT and WRITE were actually problems with the math
library functions. I rebuilt the fortran library with the hardware
mult/div and it all works.
So I found an RDOS KERMIT program source. It's actually the output
of some RATFOR, for FORTRAN 5, but hopefully I can get it to
compile on FORTRAN 4.
My problem is more contemporary.
The kermit source text is on my "terminal" linux laptop. I'm using
minicom. I need to do
XFER/A $TTI KERMIT.FR
on RDOS to input the text, but minicom blasts the text out too
fast. I solved this problem in another world at another time by
writing a "text upload" that dynamically watched for character
echo and self-paced; is there anything like this around?
I guess I could hack something up in Perl, to simply delay 25mS
per character, or something; or extract the CPU card and set the
console speed to 300, bu sheesh, the source is 68,798 characters,
I have to debug fortran4 vs. fortran5 issues as it is, I don't
want to chase down dropped single characters at the same time.
Is there any linux tool to do this sort of console-bootstrap
thing, or a way to coerce minicom? (Delay after newline is
useless, tried that, even 999 mS.)

FWIW, I'm in complete agreement with Dwight, and well remember the

Actually, it's still there - but has become an alt.fix.my.pc group.

Quoting from the Wired article:
"A new book tackles modern computers in a uniquely hands-on way -- by
getting the reader to build a replica of one of the most famous personal
computers of all: the Apple I."
"Apple I Replica Creation: Back to the Garage by Tom Owad explores the
architecture of modern digital computers through the process of building an
Apple I replica for about $100."
Wired News,
http://wired.com/news/mac/0,2125,66742,00.html?tw=wn_tophead_3
"The book focuses on the basic knowledge of digital electronics required to
understand how the computer does its most basic work. Many diagrams and
photographs illustrate specific tasks or functions.
But the book is not simply a cookbook directing readers to "insert tab A
into slot B." It attempts to teach the fundamentals of digital computer
design along the way.
The "Digital Logic" chapter, for example, which can be downloaded as a
sample chapter (.pdf), shows how to build "and," "or" and "not" gates from
resistors, diodes and LEDs.
Owad said building microcomputers is within many readers' grasp, if they
have the appropriate guide.
"Apple I Replica Creation attempts to be that guide," Owad said. "
The Woz himself wrote the Forward to the book.

It was originally written by Tim Patterson of Seattle Computer Products, as
86-QDOS (Quick and Dirty OS). The initial purchase by Microsoft was for
$15,000 IIRC, but full rights to the OS were purchased later for a larger
sum. Patterson was originally planning on including multitasking, but did
not due to time constraints. The OS gained tree-structured directories and
I/O redirection/pipes (< > >> |) in 2.0 (inspired by UNIX), and a major
rewrite for 5.0 (I believe this rewrite was largely the work of Charles
Simonyi, but could not be sure).
Tim Patterson was hired by Microsoft for a period of time.

I am curious about what is in the HSC70 but the the door is locked and
the key is lost. There should be a PDP11 and several HD's inside, at
far as I know.
I think people on the list might know how to open the door without a
key or force. The lock is not the round cylinder type found on a vax

Thanks.

Subject: Re: Re installing XP on Sony
The point is that if I went onto a PC mailing list and asked someone to
help me troubleshoot my Commodore 64, I would probably be ignored,
possibly even laughed off, and rightly so.
So, even if it were true, which in my experience it isn't, does this mean that
we have to be equally rude and condescending?
Actually, in my experience the people on the PC & other lists I'm on tend
to be quite helpful with off-topic questions if they can, or (nicely) suggest other
resources if they can't.
I would have thought that especially this list would be more mature and polite
(as indeed many people here are, although they tend to be rather quiet).
I always have to remind myself that there are a lot of other people on
this list who don't say anything unless they actually have something
useful to contribute.
We have a very special mailing list here with a specific character, which
is of great value to people in this hobby. If we allow really common,
unextraordinary PC maintenance issues to be discussed any old time someone
wants to bring them up even though there are an infinite number of tools
and resources available only a few clicks away, we'll lose that unique
character, and subsequently most of the people who currently inhabit this
space who are valuable resources for the hobby.
Well, actually I correspond with several people who used to be on this list and
have/are valuable resources who have unsubscribed because of the amount of
irrelevant garbage and the "attitude" on this list; I doubt that the occasional
PC-related topic would have bothered them. I went through my email files from
before I unsubbed a year or so ago to find people with whom I have unfinished
business, and quite a few people who used to be useful contributors seem to no
longer be heard from now that I'm back...
It would be interesting to know how many actually unsubscribed, and why.
Every person who unsubscribes because of the way they're treated or the amount
of junk on this list is a lost potential resource.
Folks have used the list in the past to ask PC related problems, but that
has been in situations where they have already exhausted all other
resources, or they are in a serious pinch and needed immediate
information, and they always explain this. This has been a rare occurence
as most people respect the character of the mailing list and its members.
Jim's issue could've been answered after 5 minutes of Googling.
So what? I ask and get asked lots of questions of/by people, and I've never
said or heard "Don't bother me, look it up on Google!"
As to the "character" of this list, it appears to be a place where you can talk
and ask questions for days about just about anything, cars, guns, what have you,
ignoring pleas to "finally get off this OT topic," as long as it's not about what
many if not most of us actually have sitting in front of us, a PC-compatible,
maybe even (God forbid) running a Microsoft product. Are you really afraid
that if we do answer the occasional OT but computer-related question that
we'll suddenly be deluged?
Can't we (at least some of us) be a little nicer, especially to "outsiders" who
may not be aware of our anal attitudes, or would that totally destroy the
"character" of this list?

Hello everybody,
I own a Honeywell H316 computer and I am looking for other people who
also own Honeywell x16 computers.
At the moment I know only two other people with H316 computers, one of
them with a working one and the other with a strange-behaving one...
I also have some software for my machine:
- FORTRAN IV + library (with source code)
- DAP-16 assembler (with source code)
- memory and cpu test programs etc.
- some loaders (with source code)
It would be interesting to get more software. A basic interpreter would
be really great!
I am also perfectly equipped for paper tape backup/copy and generation.
I am further looking for peripherals, spares, cpu options, docs etc.
Simply *everything* x16 related...
Who is Will Jennings? It seems to be a bit complicated to contact him.
He has posted an interesting message a few years ago. Saying that he had
have saved a lot of H316 CPU stuff. Where is he? how to contact him??
There is also a small website where I document my H316 activities:
http://h316.hachti.de
With best regards,
Philipp :-)

They're the standard XXDP disks that came with a microPDP-11 -- they
were probably supplied with your microPDP-11/73 when it was new.
They're no use for a VAX.
Aren't these the same disks you asked about last May? I posted a
listing of the directories then.
There is a manual for XXDP, but I don't have it (unless it's buried in
my microfiche somewhere, which I don't think it is). However, I put my
notes and extracts of the help files on my web page a long time ago,
and you can still find them here:
http://www.dunnington.u-net.com/public/PDP-11/XXDP.pdfhttp://www.dunnington.u-net.com/public/PDP-11/XXDP.ps
(same contents, just different file formats).
Those will allow you to work out what most of the files do. There's
also a partial list at
http://starfish.osfn.org/rcs/pdp-11/xxdp/xxdp25_notes.txt
Al and Henk had a discussion some time ago about scanning the documents
(program-specific instructions and listings) for each of the
diagnostics. Each one is normally known by a name like ZRQBH0, or more
often just ZRQB, where the first letter refers to the processor type,
the next 2 to the device, the fourth to the test number. The last
letter and digit are the revision and patch level -- so ZRQBH0 is to
run on any processor ("Z"), to test some part of an MSCP disk system
("RQ"), test "B" -- actually it's the formatter for an RD51 or RD52 on
an RQDX1 or RQDX2 controler (ZRQC is the corresponding formatter for an
RQDX3). It's therefore slightly unfortunate that Al indexed his by a
different scheme, but not too hard to find what you want (if it's in
his archive). Look at
http://www.bitsavers.org/pdf/dec/pdp11/XXDP/
for some scans. The initial "C" on some of the names refers to the
media it was supplied on. It's not really part of the name. Henk has
summaries of some that are relevant to his interests, on his web page
at
http://www.pdp-11.nl (see the menu entry for XXDP on the left)
which are fine to get you going, but many of the disgnostics halt on
varous errors, and you often need the listings to see what caused the
halt, or to do more than simple tests.

I will dig up my notes getting characters in and out a M7800
in my 11/35 resurrection using the front panel several years
ago.
This is also an advice: make notes of *everything* you do on
a system, no matter how trivial at this time. Changing a wire,
trying some toggle in tests on the console, behaviour, measured
voltages on pins, etc.
If problems occur later you can go back and do all tests from
your notes. That's why I can write my tests with the M7800 when
I get home (in a few hours from now).

There is a massive collection up for grabs right in Dallas. It was mentioned here on the list recently. I would love to get in on the deal [for the PDP-8 stuff specifically], but the distance, size of the total lots, etc make this look impractical.
FWIW: I was talking with the owners of the collection about a year ago. At that point they did not want to sell, but were suffereing major cash problems, these apparently have become "fatal". As far as I can tell (based on some long phone calls) the equipment has been fairly well treated.

Hi
The Polymorphics DOS uses <disk>dirname>filename.ext or
<disk>dirname>subdir>filename.ext .
It is funny in that the file names and directory names can
be up to 32 characters but the extention is only 2 characters.
If using the disk name, it can only be 8 characters.
They also had subdirectories from the start. This DOS is like
most of the older ones in that it one had to PACK every now
and then to recover deleted disk space. Since it was created
before DOS, I wonder where it got its roots?

Tha Altair32 Emulator uses sounds for feedback (all disable-able) for the
switch clicks, drive door, disk head movement (load/unload/step) and system
fan spin-up, run, and spin-down. And, no, I don't run the fan noise for the
whole time :-)
I have some of the same problems as Jim in that the sounds disappeared on my
development machine (Windows 2000 and Visual Studio .NET 2003) when I
upgraded from Visual Studio 6 to .NET. I believe that the sounds work on
machines other than mine, though.
Oddly enough, every once in a while, the sounds will appear, but only
briefly, before disappearing again.

My Sol-20 emulator has sound effects. There fan startup and running
noise, the floppy disk door opening and closing, floppy disk head
stepping, floppy motor start and stop, and disk friction noise. Since
the real keyboard makes enough noise on its own I don't see what would
be added by having fake keyboard noise too.
http://www.thebattles.net/sol20/solace/solace.html
When I recorded the sounds I first used a dynamic microphone but the
coil picked up more RF hum than anything else. An electret mic fixed
that problem. It took a while to splice the fan sounds so they would
loop nicely. The head stepping sound is of it stepping one track, but
it does a fairly good job even when there is fast head stepping.
One other thing I have done is to emulate the music card -- just a
single pole RC lowpass filter hooked up to the S-100 INT* line. The
"MUSIC" program would take a score and compile it into a program to
toggle the INT line to produce polyphonic music -- although the notes
aren't very well tempered as they get higher in frequency. It is pretty
impressive that it works as well as it does:
http://www.thebattles.net/sol20/d-minor.mp3
I recently upgraded PC's and now my own emulator doesn't run right and
the sound comes out only when I'm using the debugger. I guess it is
about to time spin a revision on the emulator.

Hi
I think many don't realize the damage that can happen
when the group becomes a "Please fix my PC" group.
I watched this happen to a news group that had too many
people that tolerated such off topic post. From Jim's own
words, he thought that this was a general computer
group. It is not.
While this group tends to wonder off topic every now
and then ( I'm partly guilty of some of it ), it is
still one of the best resources for general information
on what we like to term as classic computers. We have a
general 10 year rule. Although, we are seeing many PC's
getting into the time frame, it has not shown up as a major
collectable area. Question on fixing a MFM drive would
be on topic partitioning XP is not.
The primary purpose is to keep from having things fall
into day-to-day computer operational problems. As Sellam
says, this is not the right place for these. While there
are many on this list that see little harm in fielding
such off topic questions, I doubt they have seen a group
destroyed as I have. For those that defend him, I doubt
you realize that this group can be quickly destroyed by
such sympathizes.
When I step off topic ( and I have a few times ) I have
no problems or animosity towards those that chastise me
for doing so.
If Jim feels that there is little purpose to this group
because we are unfriendly to question about using XP,
maybe he has an incorrect understanding of what this
group is chartered for. I would like him to remain in the
group if he has interest in older classic machines. If
he doesn't then he is right to leave but there should
be no hard feelings as it was just a mistake that is
quickly rectified.
Dwight

Alas I know of no recordings, and to be honest I can not remember the tune itself. What I do remember [this was a school district computer]:
1) Having a heading from listening to Bill K, and Erich F "tuning" the program
2) Mr. "C" [music director] coming down and spending hours critiquing!

'/' was already taken up for the command line switch introducer character
(not '-' since CP/M and DOS were originally inspired from the culture of
DEC OS's rather than the UNIX culture).

Dont know "who" but the alleged "why" was to avoid confusion in parsing (switches used "/" [same as DEC,CP/M] rather than "-" ala Unix.

Sounds (sorry) like a good idea. The inspiration for HAL singing
"Daisy" when he was lobotomised by Dave Bowman in "2001" was that Bell
Labs had demonstrated an IBM 7094 "singing" "Daisy" in 1961. Bell Labs
were doing research into vocal-tract modelling; John Kelly had wired a
speaker to one of the output bits and he and Carol Lochbaum[1]
programmed the vocal, with Max Mathews, who was pioneering digital
music, did the accompaniment. The whole thing was programmed onto
magtape, read back once complete and "played" through the speaker. The
recording they made was also once available on an album called "Music
>from Mathematics".
I'm sure there used to be an article on the web about it, though I
can't seem to find it right now, though I have found references to some
of the Bell Labs reports and tapes:
http://www.mindspring.com/~ssshp/ssshp_cd/ss_btl1.htm (about 2/3 down).
What I can find, though, is a digitised copy of the recording they
made, which I downloaded, so I've put it on my website for you:

I also have an MP3 version, which isn't much inferior (and much

I will dig up my notes getting characters in and out a M7800
in my 11/35 resurrection using the front panel several years
ago.
This is also an advice: make notes of *everything* you do on
a system, no matter how trivial at this time. Changing a wire,
trying some toggle in tests on the console, behaviour, measured
voltages on pins, etc.
If problems occur later you can go back and do all tests from
your notes. That's why I can write my tests with the M7800 when
I get home (in a few hours from now).

Just a follow-up:
Turns out that the problem was with the way the cards were installed in the
Q-Bus. The mixed Q22/CD-serpentine backplane doesn't allow you to insert a
Q-Bus card in the C/D slot of row 3. moving the three dual-height cards to
the left hand side of the backplane fixed the problem and allowed the system
to complete its tests and boot successfully.

Born in 1966, started with 4K chicklet-keyboard PETs at the downtown
public library in 1977 (none of my schools to that point could ever
afford a computer). Had a friend with a Quest Elf around the same
time frame, so jumped from 100% BASIC to mixed assembler/BASIC pretty
early on. Saved up half the money for a PET 2001N-32K (still have it)
in 1979. Got first computer job at 15, programming a prototype C-64
(s/n P00002008) for Bruce & James Software, "Wordvision 64" demo.
They went on to release Wordvision for the PC before going bankrupt.
Wrote kids games published by Reader's Digest Software until that
company folded when Reader's Digest terminated their kids software
line. Picked up a PDP-8/L at the Dayton Hamvention, in the meantime,
starting a long association with DEC computers. Turned that
association into a career with Software Results Corp, making
HASP/3780/SNA COMBOARD protocol engines based on the MC68000, first as
hardware technician, later as System Manager, finally as lead
programmer. Got my first taste of UNIX there, in 1984. After a few
minutes on a VAX-11/750 w/2MB of RAM and 2xRK07 (28MB) running 4.1BSD
(that I now have in my quonset hut), I *knew* that UNIX had a future.
I've spent the past 20 years doing UNIX and VMS administration and
programming to different degrees at different places. Started
dabbling in Linux with the 0.9 kernels, whenever they added native
(non-patched) SCSI support. Did first Slackare install in mid-1992
>from a huge stack of numbered floppies.
Just got back from a year at the South Pole running a neutrino
telescope (AMANDA) for the University of Wisconsin, that depends on
two dozen Linux machines, and a dozen VME crates to collect, archive,
and forward gigs of data per hour. It's been one of my favorite jobs
of all time, not just because of the location, but because I got to
use all of my admin and electronics skills I've been building for my
entire career.

This is the halts disabled position. Set it to dot-in-the-circle (halts
enabled) and it should give you the >>> prompt.
In the halts disabled position is attempts autoboot. I assume that the
hang you are seeing is the result of autoboot not succeeding / looping.
Setting the dot in the circle will disable autoboot and give you the console;
you can then check your system out manually.

I have been playing around with a collection of old Flip Chips that I
have and put together a VC8/I compatible scope controller for my PDP8/e.
You can find a page about it here http://www.chd.dyndns.org/pdp8/VC8/
The only reason this was possible was because I had two 10-bit D/A
converters (A618), the rest of the modules are pretty common.
Thanks to David Gesswein for some test programs.
