I'm still digging. I found more 550 stuff. I think this is everything
that came with the 550. Here's a chance for you 550 owner's to get the
whole set at one shot!
Original DS-DOS box and invoice.
Original Sanyo Easywriter ver 1.3 disk
Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two
original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4
are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1
Original Sanyo disk box with all three original disk of set A, WordStar
and CalcStar and a backup copy of DS-DOS.
Two card board dummy disks used to protect the floppy drives duing shipment.

Does anyone have docs for this beastie? it's an apple-II on a card that
goes into an XT... or does anyone have any interest in it? it's been
sitting on my shelf for ~ 12 years now...
I have come across an Osborne model OCC1 Serial # 134033. This unit has the
300 baud modem. It also has 5 1/4 disk with it. (SuperCalc, WordStar,
Qbasic) The unit boots up and runs the software but after about 15 to 20
minutes it starts to overheat.(smoke)
My question is - What is the selling price for a unit like this and where
would be the best place to sell it?

Yesterday I finally got a couple books I'd gotten on eBay a couple weeks
ago, obviously "VAXcluster Principles" is an interesting book, but I was
surprised how good of a book "The Digital Dictionary" is. I got the 2nd
Edition (the first was mainly internal use). It's a dictionary of all the
different terms that were in use around 1986. As such it contains info on
the PDP-10, PDP-11, and VAX, as well as DECmate's, Rainbows, and
Professionals. As well as the Apps, Languages, and OS's. Great book if
you want to know what a specific term or acronym means. Well worth picking
up if you are in to DEC stuff and can find a copy!

Looking for info on the Dynalogic Hyperion, a "portable" DOS machine
manufactures around 1983. At least the one I have is 1983. it was designed
and initially built in Ottawa, Canada. Hyperion was acquired in about 1983
by Bytec, who was later bought by I think a Quebec company called Comterm.
Anyway, mine has stopped working: The machine still boots but no image is
displayed on its 7" diag screen. Hence I am looking for service info and/or
persons who have worked on the machine.
Any leads would be most appreciated.

Hello to all VAXenfolks,
i do have a problem with a VAX-11/730 that i have reconstructed
(cleaned,
resoldered, replaced cable, everything. Pictures on www.vaxcluster.de.
Yes,
i am a bit proud of it... But sorry for the bad web-page design!) over
the
last few months.
It is now willing to boot and tries to load it's microcode tape from the
TU-58 drives. I even have a microcode tape which looks like it could be
still readable.
But the TU-58's are so battered that i have not been able to read the
tape.
I have repaced the rubber rollers, but the read/write-heads look, ummm,
bad!
I have found somewhere some TU-58 simulator software for DOS which looks
like a promising alternative; i would place a mini-DOS-computer inside a
VT-102 and route some additional cables to the VAX and bee fine.
BUT: How do i get the contents of the microcode tape of the tape, into a
DOS file without access to a working TU-58?
Is someone on this list able to read the tape?
Has someone already made a tape image i could just use? I mean, i have
a original DEC tape, with serial number and all. I might even come up
with a license document, if i search long enough...
Any help would be greatly welcomed. This old lady is just to beautifull
to use it as an electric heater only...
Thank you

Depends on what you mean by "fancy animations." It will probably do better
out of the box than most new peesees depending on what you'd like to
animate. (and whether it requires texture memory, of course) Both of my
SGIs, for instance, have analog video in/out, which is a start. On the
other hand, you can't really do a good animation with anything "out of the
box." It usually takes a lot of strange stuff.
The graphical prowess of the machines is still something, though. For
instance, the ability of the machine to provide individual color-maps for
different windows on the screen, without the nasty palette-flashing that's
seen in xfree86 on an intel box (for example) when you try the same...

I need an RM03, preferrably within sane driving distance of Peoria, IL.
Having a KS10 as a paperweight is absolutely no fun. I can trade PDP-11
stuff for one, I have all sorts of 11 kit that I'd be more than willing
to trade for KS10 stuff.
Also, if anyone has the 120V-AC plug that goes in a TM02, I am short one
of those as well - I have the 220 volt version (but the rest of the drive
is all 120 volt parts; Odd!)
Basically, I'm sick of using the KS10 as just emulation validation and I want

Okay, in order to pose this question I have to come clean here and admit my
age:
Right around 1960 or '61 (I was five or six years old at the time) I was
given a toy computer. I suppose it was meant to represent a mainframe
(what else could it have been, given the era?) and there was a rectangular
(4 x 8? 5 X 7?) array of blinkenlights on the front of it. There was also
a tray in the front which accepted a small punched card. A set of these
cards came with the toy. Each card had a multiple-choice question printed
on it, as well as four answers to choose from, numbered A through D.
Additional card sets could be purchased separately.
When a card was placed into the tray and the tray was then closed, the
blinkenlights would display a "random" pattern for a couple of seconds
(always the same pattern) and then the array would display the correct
answer to the printed question, A B C or D. It didn't take long for me to
be able to read the holes in the cards, and I even "modified" a couple of
them so that the toy displayed an incorrect answer.
Does *anyone* remember this thing? It must have cost a few bucks back
then. What was it called?

Well, setjmp and longjmp are pretty powerful. see
http://www.cs.uiowa.edu/~jones/opsys/threads/
for a machine-independent user-level thread package implemented in C using
setjmp and longjmp for control transfers between threads. It comes very
close to what a real coroutine afficianado would like. (Writing the
thread launch code in a machine independent way was murder.)
Curiously, the same thing can be done without longjmp()! I had a student
write me a thread package in Pascal once. All he needed was a mechanism
to convert pointers to integers and back again (easy enough in standard
Pascal, so long as it doesn't check variant records). Given this, his
code did essentially the same thing as my thread package.

Most of the engineers I work with have never heard of Amphenol or Cannon,
let alone "blue range" or "red range" (popular Cannon connectors)
It's a classic chicken and egg thing. Ampenol connectors were adopted as
a "standard" connector for Centronics printer, IEEE-488 and SCSI interface,
but are often mis-named. As I don't have an Amphenol catalogue to hand,
I'm afraid I can't tell you what Amphenol's designation is for this connector.
On the subject of D-sub connectors I've sometimes come across some with
metric threaded jackscrews instead of the usual UNF thread, or is it UNC ?

Had Bosch come up with EFI already by 1968?
Every VW (and Audi & MB, etc) of that vintage that I've seen used
CIS, which was a purely mechanical system.
I have seen a 1969 Audi Super 90 (wagon) that had an aftermarket
Capacitative Discharge Ignition (CDI) System... by 1974, Audis
had those as stock, while CIS was still 1 year off...
My 1986 Audi 5000 CS Turbo Quattro uses a Motorola 6802-based
controller... very simple to upgrade, too.... ;-)

Hi,
after a quick excursion in getting a PDP8/A up and running (as far
as that gets without any peripherals other than the programmers
console :-), I'm now back to the big toy. The 6460 is still waiting
to boot Ultrix.
Recap: it's up and running from VMS 7.2 or VMX 5.6 from RA90
disks through KDB50 and KDM70. I don't have any working IP
communication because the VMS 5.6 just doesn't have anything
and 7.2 has MULTINET which just refuses to run with the old
license key, nor with a cheat hack, nor with a hobbyist
license key. So I'm now down to transferring files through
modemspeed. (I could write a TK70 or 9-track tape at my
workplace, but that's a hassle by itself, so I keep that as
a last restort.) Luckily I have kermit on the VMS 7.2 so
I have a convenient yet slow way of transferring files.
I also have a boot tape from Isildur. That's Ultrix 4.1.
That version seems to not support the 6400, it boots up
until a certain point and then simply halts. I'm very
sure it is *not* a tape read error and that the boot
process fails somewhere after the VMB is loaded and probably
at the point where vmunix is started. I assume it just can't
get a hold of the console at that time to put out an error
message and just dies. Even the primary ultrixload will
dump an error message before it halts.
The more recent developments:
I also have an Ultrix-4.5 CD. But no CD ROM hooked to the
VAX and no other VAX (InfoServer) with CD ROM and so I
cannot boot that. I could possibly just write the CD ROM
image onto a disk verbatim and fingers crossed boot from
it. However, I cannot pump the 178 MB through the 9600
b/s line, or else I have to have that thing up for 2
days and two nights only for something that might just
plain not work.
Interestingly this CD is not an ISO file system but a
simple UFS written to the CD in 10 kB blocks. FreeBSD's
mount unfortunately cannot mount that. However, I just
dd'ed an image onto disk and vnconfig - mount form there.
It's read-only and disklabel doesn't make any sense out
of it, but I can read everything just fine.
Today's news:
So, I decided I make myself a bootable tape from the
reverse engineered Ultrix 4.1 boot tape and the new
4.5 files from the CD. The Ultrix boot tape comes with
a vmunix that apparently has some sort of standalone
memory root file system. Then it supposedly is able to
set up a disk and install a dump backup onto that disk.
That dump backup contains mkfs, disklabel, ifconfig, rcp,
uncompress, and tar, so I have everything to set myself
up even if the autoinstaller cannot deal with my hack.
The boot tape I could read from VMS.
$ MOUNT/FOREIGN/BLOCKSIZE=512/RECORD=512 MUC6
$ COPY MUC6: FILE.00
$ COPY MUC6: FILE.01
$ COPY MUC6: FILE.02 --> ERROR
$ DISMOUNT MUC6:
$ MOUNT/FOREIGN/BLOCK=10240/RECORD=10240 MUC6
$ SET MAGTAPE /SKIP=FILE:2
$ COPY MUC6: FILE.02
$ COPY MUC6: FILE.03
$ COPY MUC6: FILE.04
$ COPY MUC6: FILE.05
...
and so on. It's got some 40 or so files on it. What there
files are we are being told from the ultrixload.c source
code.
FILE.00 is the ultrixload image, about 18 kB in size.
Ultrixload is said to load either vmb.exe or a
standalone kernel from a non-file structured device.
The layout of the boot device is descibed as:
FILE.00 - ultrixload
FILE.01 - a combo consisting of
- descriptor block 1 512 byte block
- vmb.exe (optional)
- vmunix (compressed if not a TK50)
This magic descriptor block is described as:
struct desc {
union {
char pad[512];
struct {
struct exec x; /* a.out image header */
int nblks; /* num of 512 byte blocks on medium */
int vmbblks; /* size of VMB in 512 byte blocks */
int compressed; /* 1 = compressed, 0 = not compressed */
} d
} un
};
By loading the initial portions of the other files down
to my BSD system and using file and stuff, I figured the
other files:
FILE.02 - the ROOT file system dump
FILE.03 - an uncompressed tar of the instctl files (on the CD)
FILE.04 - a compressed tar that is called ULTBASE450 on the CD
FILE.05 - a compressed tar that is called ULTBIN450 on the CD
...
and so on. The instctl tar begins with a file called ULT.image
and that is just a list of files beginning with ROOT, ULTBASE,
ULTBIN, that apparently correspond with the files on the tape
in that order.
So, my plan is to fiddle with files 0 and 1 only and keep the
rest, as it should be compatible with the 4.5 kernel. That
reduces the amount of data to transfer tremendously.
Quickly I found that I have no ultrixload on the CD, so the
old version will have to do. As I have strong indication that
that works, I can leave it at that.
Remains to work on file 1, that funny combo of descriptor,
vmb.exe and vmunix. The tar file 4 (ULTBASE) contains a
vmb.exe as well and so I could compare the two files that
came with ultrix 4.1 and 4.5 respectively. They were both
the same size and actually both the same. I successfully
extracted another exact copy of vmb.exe using
dd if=file.01 bs=512 of=vmb.exe skip=1 count=86
So, whatever VMB.EXE is for (sounds like a VMS boot block),
I can reuse the old one. Given that I have a standalone vmunix,
all I'd need to do is cut and paste that somewhere after
block 86 to the end of file 1 with a few cat and dd operations.
But here the problem starts. I cannot interpret the descriptor
block very well. It tells me that the VMB.EXE is 86 blocks
in size and that is exactly 44032 bytes, that corresponds
with the actual size of the vmb.exe file from the tar archives.
Good, but apparently the vmunix is not a complete piece.
Apparently that descriptor block's a.out header slot actually
holds the a.out header from the vmunix file and the vmunix
file is right after the vmb.exe without it's a.out header.
I also see a lot of 0 data in that region. So apparently I
will have to fiddle with that a.out header and need to know
just where to cut vmunix. That is a problem.
I will try to figure that out somehow. My hunch is that the
a.out block (which I haven't been fiddling with since I
ported Kyoto Common Lisp to 386/BSD 0.1) allows for the
executable to actually have some other stuff like that vmb.exe
before the actual start of the executable image. I have no
idea though what the purpose of this stupid vmb.exe is.
All in all I'm optimistic. I'd love to make a boot tape with
4.5 Ultrix that I could then share with my friends (that
is you) who also want to get their 6400s converted to Unix.
As always I'd be thankful for any helpful ideas you might
have.
regards,
-Gunther

I have a couple of the Heath serial cards (one unsoldered!), the H-27

The heath seriial card was a fairly flexible card copared to the usual DEC DL-11.
to debug the H-27 (he never used it). Except for the monsterous holes he blew in the side to mount additional fans, and the holes in the front he added for external console baud rate switches, it resembles its original

The fans and switches were a common mod and handy too.

Hi,
I'm ripping my hair out over VMS (as usual). I have a little
magic file that I need to transfer from PC to VAX. And
kermit on both ends. I thought I knew how to use kermit,
but no matter what I do, the file will never work as an
executable on the VAX. It always complains about a corrupt
descriptor block and it comes up too long. The file is
exactly 2048 bytes long and when I send it it comes up as
5/6 blocks with DIR/SIZE=ALL. That is one block too many,
isn't it?
The funny thing is, when I do a round trip with kermit
PC -put-> VAX -get-> PC, I get two identical files on the
PC. But when I do VAX -get-> PC -put-> VAX of a working
.EXE file on the VAX, I end up with a broken copy (same
error.) So, what can I do?
I have SET FILE TYPE BINARY on both sides.
I'm so sorry for bothering you with my VMS ignorance, I
greatly appreciate your patience and help.

I agree, last year they couldn't even build a set of LED Christmas tree lights
without blowing them up, never heard of constant current drive !!! I'm not
talking
about graduates straight out of college but people who've been in industry
for a
few years. In the engineering department I work in there is only ONE other
true
practical engineer who lays out his own PCBs, is keen to learn about new and
emerging technologies etc. He is, like myself, mostly self taught, and has a
passion for this stuff - a rare breed these days. But there we are - pay
peanuts
and get monkies.

Agreed, I believe any so called engineer should have a practical "hands on"
experience in both hardware and software, after all if they don't understand
the
basics they are of little use.

One day I will have to do a search for the original IEEE-488 standard just to

i agree about the os but i dont agree on the attempt part
dont attempt it. do it. a computer is not that complex of a machine
at least a pc. an os is all theory and vision.
u can think up an entire os away from any pc.
u could then just go in and code the entire thing.
the hard part is thinking up what it is that u want
and how it has to work. the coding and so forth
is the easy part. this is the exact project i am working
on now

A local general purpose mechanic who mainly works on Ski-doos in the
winter and pumps and everything else in the summer gave me a complete
Adam (!) collecting dust on the shelf, when I told him I collect computers. He
mentioned he could use an old box to keep track of his parts inventory if I
had any spares. I volunteered to supply him with something that would serve
simple needs thinking of everything from a C-64 to an A2 or an XT to a 386
and that there must be 100s of programs that would be available. And no I
don't want to configure a Database program.
I did a Google search and found only the newest Gee-Whiz Winblows 9x,
2k, XP, and OSX programs, and while I haven't searched Simtel, out of
frustration I've decided to defer to the list about older programs to track
inventory and if it also has billing and labour, so much the better.
Any suggestions would be appreciated. It would serve as an example that
older machines don't have to be delegated to land-fills. This area is in north-
central Manitoba,Canada and not exactly a hotbed of technology. The
temperature at present is -20 C, but the air is breathable.

Hi all,
The thread on cleaning cards by running them through
the dishwasher was timely as I am resurrecting an
HP3000/XE. The system came from Pacific Pipe in
Oakland and is the *filthest* system I have ever seen.
The "computer room" on the second floor was left open
to the work yard and all matter of dirt, dust, grime
etc was sucked into the CPU, disc drive and tape. The
CPU boards literally had a layer of grime covering
them.
Of course since this was an HP box it booted right up
even though it was basically "clogged".
Many of the HP cards have paper stickers indicating
part number, revision, etc. Any thoughts on preserving
these through a dishwasher cycle? Or should I just
gently hand rinse? THanks!

I'd argue that engineering is all about making things. OK, perhaps engineers
don't need practical skills so much these days, but an understanding of other
engineering disiplines is essential. You have to be able to understand the
"other guy's" point of view, whether it be hardware, software, manufacturing
or management.

I hope you meant Faraday as the "father of electricity" and not Edison.
As for Marconi, I'd say he "pioneered" radio engineering but wouldn't have
got very far if it hadn't been for Hertz. I'm not sure how Tesla fits into the
picture, he did invent the squirel cage induction motor but I'm not aware
of any major contributions he made to radio engineering.

Ahh, those "engineers" who don't know which end of a soldering iron
gets hot.
A fond memory from around 1991, while working for a small defense
contractor in NJ, talking with a 2nd-year "summer slave" on loan from
MIT (of all places!). I'd assigned him to write some data reduction
code in FORTRAN for a remote sensing project, and later wound up
having to do it myself:
Me: "This program needs a lot of work."
Weenie: "Hah! Where did *YOU* go to school? See here:"
[weenie scribbles some incomprehensible equation on the whiteboard]
Me: "I didn't. But I damn well know a REAL*4 on this VAX won't
deal with the IEEE-format floating point numbers from the
spectrometer without format conversion, for starters.
Weenie: "WHAT?! [horrified look] You actually want to RUN this program?"
Me: "Of course. Why the hell do you think I asked you to write it?"
Weenie: "Isn't this just an exercise?"
Me: "We are a defense contractor. We build machines to kill
people. Look at the size of my gut...we NEVER exercise
around here."
Weenie: "Does this mean I have to type this program in, like on a computer?"
Me: "No. You're fired."

I had been taught that was a Rj-11 "handset", which has never really sat
well with me... but it is what I was taught, and it is what my telco
catalogs list the part as, so I had to accept it.
Thanks to that link, it is claimed to be an RJ-22, which sits MUCH better
with me since it has its own designation. I can't speak for its accuracy
as it is the first time I have heard that, but if I had to pick, I would
go with RJ-22 over RJ-11 "handset".
Oh, and I was taught in the field all my telco knowledge, never went to
school... it is learned from various Bell and private
installers/techs/whathaveyou... so who knows how accurate they are, but I
tend to give them more credence than most schools (except maybe some Bell
installers, the older ones are good, but most of the younger ones suck
royally)

It's important to note that the RJ designations specify not only the

You DEC old-timers out there will probably chuckle at my little
"discovery", but I'm posting my findings for us who are "DEC challenged"....
Yesterday I was pulling my hair out trying to get my VAX 4000-500 to
recognize an external RRD-43 CD-ROM that was attached to a KZQSA SCSI
adapter. No matter what I did, it wouldn't recognize the fact that anything
SCSI was connected.
The problem turned out to be the address that the KZQSA was set to. It was
set to address 761400, and the 4000 was reporting the card to be a DEFQA,
which to even a DEC newbie as myself, was VERY wrong. A search through the
"VMS wizard" archives at Compaq.com turned up the statement that the KZQSA
was shipped with a default address of 761300.
So I fiddled with the address jumpers and set it to 761300 and *voila*, the
4000 found the KZQSA. I hooked the external SCSI enclosure to the card, and
it found the CD-ROM.
It was able to boot VMS from the CD, and I'm on my way.
Again, don't laugh too hard, I hope this message helps others who are
"Unibus Ignorant"....

Many thanks for this tagline to a fellow RGVAC'er...
My sister-in-law works at the Post Office and knows lots of the
local customers. She happened to learn that one gentleman had
some "old computers" in the attic. When I called him, it turned
out to be an XOR S-100 box w/dual 8" drives, a Liberty 100
terminal, and some loose S-100 cards (including a Cromemco
serial/parallel card still in the shrink wrap, a few 8K cards
(2102 and 2114-based) and a couple of SMS video cards, one as
yet unstuffed with the chips under plastic).
No OS, few docs (some of the cards _do_ have manuals).
He kept the S-100 prototype card he once wrapped for his first CPU
(sockets intact, chips missing, wires removed).
The sad news is that he mentioned that he used to have an old computer
that he threw out... his son brought it home ($20 at a yard sale)
back when Dad had a 386 in the living room - it was a Digital Group
machine. :-(
So... Anyone have any info on XOR boxen? I have a CP/M disk for
the C-128 and stuff for the Kaypro, but nothing on 8". Can I mail
anyone blank disks to be copied onto? What sort of information
would I have to provide to be able to put together a compatible
disk? Brand of disk controller? Type and manufacturer of CPU card?
Serial card vendor?
Also, how did S-100 video cards work? Did you still have a console
terminal but use the video card as a secondary peripheral?

Not me, though, I've seen documents (probably in UAE) that say you can write disks to images and images to disks if you use it. The linux/netbsd/freebsd drivers, from all I've seen and heard, should access disks fine for making images and the like.
> I think that "MatchPoint" might be their board that you're

I was thinking of compati-card, actually. I was un-aware that it had this same limitation.
I may have to see if I can find one of these "MatchPoint" boards now, though. What are my chances?
> What software is available for Mac to do Amiga disks?
Again, I seem to remember from docs that UAE will use it directly. So you'd be stuck with a chicken-egg scenario where you need an image of the O/S (or boot disk) to get it working. :) Otherwise it would work fine.
I have seen mappings for the linux fdparam (I think that's the program..) which will make your system use the format at a low level, and have heard that catweasel works with linux. In that case you can image/unimage the disks pretty simply.
As for a program that reads/writes the filesystem (I assume that's what you're asking...), I don't know of one, but I believe that given the number of people interested in amiga emulation, somebody must have written one. If they havent, get an amiga emulator set-up, and chances are that will do it for you. (Again, I seem to remember mention of this in the UAE docs)
I would, of course, be interested to hear from anyone who's really tried it. :)

Supposing one has a farm of older, relatively slower machines (Sun-2's,
Sun-3's, early SPARCs, 386es, very small VAXen, 68k-based Macs, etc.)
running various Unixes (mostly NetBSD), networked together and connected
to the Net. What does one do with it?
I've been trying to think of some interesting, moderately useful
distributed-computing project that they could sit and crank away at
and haven't come up with much of anything. All the distributed projects
that I know of are distributed because even fast machines aren't enough by
themselves -- a trailing-edge farm can't make a useful contribution.
If network Tierra (an artificial-life research project) had ever come to

didn't.

Ethan, I have Orcad 9 Capture and Layout and could provide some PCB
resourse if needed. Design would probably be double sided. A single sided
PCB design would be prefered from a "homebrew" point of view but I don't
think it would be practical.

my thinking was to just devide the data up into threads and have each thread
work

thread could be listening and deligating and other threads could be doing

the work. not sure how much processor power it would take but originally i
was just
thinking about the network sort of just passing messages with each bot having

the work and pass text to the bot .

Yes, but could it have been done back then without increasing the
cost of the hardware very much? It probably would've involved a small
microprocessor. Hmm, could such a thing be accomplished with a lookup
