We've just been offered a Norsk Data ND100 (running Sintran), which
according to the 'offeree' is somewhat unusual in being a rack-mount
version rather than the more typical cabinet variety.
I doubt the museum can take it though as we're somewhat swamped in mini-
class machines at present, but it's destined for landfill otherwise.
Comes with full documentation and (likely) the controlling dumb terminal
and a Genicom dot-matrix printer. Was working when put into storage
apparently. The hard disk and floppy are also mounted in the rack (so no
seperate enormous cabinets! :-)
It sounds like the company may be hanging onto the rack it was put in
(which probably makes it a little easier to manage, at least for most UK
folks!) but that they may be disposing of the rack too.
The machine's currently in Reading, Berkshire.
There doesn't seem to be much info about these on the 'net - from what I
gather they're 16 bit minis with a bit-slice ALU, and microprogrammed
CPU.
Anyone able to save it? I can put you in touch if so.
cheers,
Jules

nope, that don't do it either. It's the same output on the terminal too.
What about +256? are they 8 bit chars? hmm no that would just be 27

chr$ does a MODULO right?

Ron,
The way I always cleared the screen in Basic-Plus on RSTS on a VT50 or VT52
terminal was:
PRINT CHR$(155)+"H"+CHR$(155)+"J"
The CHR$(155)+"H" positions the cursor in the top left of the screen
Then, the CHR$(155)+"J" clears the screen.
This is all from memory. I haven't actually written that kind of code
since the late 1970s.

Hi
I'm working on my PDP 11/60's and need info on the processor set.
The 1st board has LED's and thats a starting point if anyone knows
the status of the the LED's would be helpful. Or a source for
a on-line copy of the manual. ?? (kd11-k, m7872 1st board)
The second item is a maintiance manual on a TE-11 tape drive. These
look like a real challenge. ( Not sure if the TE-16 is close enough)
I don't have either manual.
Thanks, Jerry

Hi there,
Perhaps someone who is a little more familiar with the innards of the
PDP8/Ses can answer this...
Are the individual flip-flops arranged like a shift register or a set of
latches? In other words, when data is being clocked into a register,
does a bit get put into (say) AC0 then bumped along until it eventually
ends up in AC11, or are all the D lines of the flip-flops connected
together, with each one being clocked in turn?
Gordon.
In rummaging through classic computer stuff I haven't seen in a while, I
saw several things that are definitely a problem. What other things need
to be added to the list for collectors to watch out for?
* Leaky nicad batteries that will "eat" the circuit board traces
The early computers that come quickly to mind are the TRS-100, Lobo
Drives Max 80, NEC 8201A, 286 and later motherboards, and S-100
CompuWatch Clock/Calendar boards. Any others that should be added to
this list?
* Subterranean termites (eating manuals and other cardboard/paper
products)
Fortunately, they had only mostly started on the cardboard boxes, and
only damaged some of the manuals. I'm thinking that keeping the manuals
in ziplock bags might be a good idea for any manuals that need to be
packed away. This would also protect them from moisture if the boxes got
wet.
* Leaky storage areas leading to equipment and documentation being
ruined.
I've had quite a few books and manuals that had to be thrown away
(nothing really rare, hard to come by, or valuable) due to a leaky roof
where they were being stored.
It might be interesting to have a list of ways that the BIOS gets
accessed during startup. These are the ways that I know about; are there
others I've missed? I don't recall which keys work with what BIOS and
that might also be interesting information to have.
* Setup disk (IBM AT)
* Del key
* Cntl-Alt-Insert
* Cntl-Alt-S
* F1 key
* F2 key
* F10 key (Compaq)

Some of you folks who have been around long enough might remember Enrico
Tedeschi, the guy who got so frustrated by our collective inability to
understand his inarticulate premise that it was the human element, rather
than the computers, that was more important, that he threw up his hands in
disgust and left the mailing list for good.
Anyway, I heard him today on a BBC program about the 50th anniversary of
the transistor radio.
That's all.

Well, Kermit did the same thing as the two terminal programs.. Even
though they say they are vt100 compatible, they still spew garbage and
don't make the proper screen with vt50dpy... however vt50dpy
running on a serial port on the host system works fine.. I just want to
work at that terminal.
what's funny is the terminal emulators work fine with teco/vt. I
suppose vt50dpy makes more use
of the terminal control codes..
Well, Thanks for the suggestions so far. :^)

Yes, it is. I was about to suggest the same thing. An ex-PC floppy

Hi there:
I have a Vector Graphic MZ machine in nice condition except that the
Flashwriter II board seems to be broken, so using the Mindless Terminal
is out of the question. I understand that the version of the Monitor ROM
I have (either 3.1 or 4.0) does not support serial terminals so I'm dead
in the water unless I can dig up a 2.1 ROM or write my own (with two
young kids pretty doubtful I'll get to it real soon). Using a serial
terminal is fine with me until I can get a new FWII or fix the one I have.
So, I'm hoping someone out there has a Vector machine kicking around
with a 2.1 ROM - I'd love to simply drop a new ROM into the machine and
go, but a binary file will do or even a listing, I don't care. I'm happy
to reimburse you for your trouble and materials, of course.
Please reply or send me a note at gtulloch (at) shaw.ca if you can help
me track this animal down, I'd love to get this MZ back in action. Thanks!
Regards,
Gord
I seem to recall that the IBM setup disk would work on other computers
that required a setup disk.
Another useful piece of information would be the ways to access the HD
format routines on PCs. Somewhere I have a list that came from
ComputerLand that gives the debug entry addresses for a number of
controller cards. IIRC, the Xebex card required a sequence of debug
instructions to start the format routines.

Some of you may recall that back in early September I wrote about an HP
LaserJet IIISi that I disassembled and repaired after a capacitor
fried.
Well, even though I got the printer working again, I made a mistake.
Just about the time I got it working again, I left on a month-long trip
around the continent. (A few of you contacted me when I said I'd be
traveling around. I didn't actually end up rendezvousing with any of
you, and I apologize for it - I didn't realize how short of time I'd
end up being. A month-long trip sounds like a lot, but it ends up
being awfully short when there are five people/places to be visited,
and some of the trips in between are multi-day trips.)
Now, I want to put the printer back together, and there's the mistake:
I didn't leave notes to myself on how it came apart and thus how it
went back together. Would any of you happen to have a service manual
that could guide me? I could probably figure it out eventually, but if
I can save myself annoying mistakes, I'd like to.

Actually it sounds like Easy Office 2001 is the one crimping your
conversion. There are plenty of Linux tools that will do what Adobe
Photoshop does, if it doesn't run in the emulators. Same for PDF file
creation and manipulation.
The Netscape mail files will convert over pretty easily. I've done that

Sheesh, things just take so long to get around to...
THe flexo is running fine now, except for the punch. It was
of course just lubrication, the thing wasn't even dusty! The
belts are even OK, though I suspect they won't last that long
(old rubber).
The punch and reader are sticky; the punch hangs, repeating
the same character over and over (certain codes, "7", "A",
etc) so it needs a little more lube in those areas. I missed
a few linkages, hit those, and it improved. It punches fine,
the reader works, but some timing linkage isn't dropping out,
I'm sure it'll be fine.
Whale oil or whatever it wants is long unavailable (nothing
specified in the manual) so I'm using 0-weight synthetic motor
oil. Motor oil is generally UNrecommended in old gear, but the
new formulations (like synthetics) are pretty good and don't
gum up. I used synth grease for the open gears.
I've only got the offline Flexo cable, the one meant for the
second flexo for offline tape preparation. I had to leave the
second flexo behind, Ed wouldn't part with it (aargh). This
one seems fine though.
The cable is all cracked, like it's made of dried pasta. Slightly
scary, but that's what circuit breakers for.
There is a big electrolytic in this thing, a filter for the
relay supply, but I said hell with it, if it vents it vents,
but it seems just fine, lucky me. Of course it could be open
and relays will buzz, but I'll find that out later.
I was digging through some old papers and came across a 48-page
advertising brochure for the PDP-9, in great condition except it's
slightly "buckled" from sitting sideways in the box. It's called
"PDP-9, The Serious Computer" dated 11/67. I can email pictures.
Anyone interested? I have no idea if it's worth anything to anyone
but if so I'd at least like to break even on the postage ;)
thanks

2. One Tandy memory board with 8-1MB 90ns memory sticks on it. It has several numbers on it and I'll list a few. 1700 361 Rev. D, 0508 LEIU 7V, 1990 (year of manufacture?), P/N 870-9838, 889-9216200. Again I was given this unit so don't know for sure if everything is OK with it, but it also looks to be in excellent condition.
Let me know is there is any interest in either of these items and for a few bucks plus shipping costs it can be yours. I will be glad to answer any questions on either of these items, just email me.

Greetings. I have a Diversified Numeric Applications

to have a removeable disk pack unit and drum printer, but they are gone.
I do have an engineering manual with schematics, and a book of
diagnostic program listings. I've had to 'repackage' the major
components into a different 19" rack. The CPU, MUX, and DISC controller
bays are wire-wrapped 9000-series TTL logic. It's very cool. I'd be
interested in any information about this machine, and hopefully anyone
else who has one. fordms(a)gte.net

Thanks - just what I needed! :-)

Heh - I was staring at DEC engineering drawings for hours and it was
giving me a headache! I need to look at all the info for the memory
crate though as the CPU still isn't happy (the run lamp's permanently on
and we can't halt the CPU or toggle any data in from the front panel).
All cards look to be OK in the CPU though, but I suspect there may be a
problem with the memory...

No problem - we're not intending on using it either; I just wanted to
check that it should be OK without it. Time to do some reading this
week!
We did discover the limit of the power cabling in the museum room though
- with the 11/34, 11/44, HP T500 and a few assorted terminals running we
hit the 30A limit on the breaker and blew the power out to the room :-)
Luckily we've found a few power outlets that are on a different breaker,
so we can move some big stuff over onto that and spread the load. Still,
adding the Marconi machine, Elliott 803 and the Decsystem 570 with the
three massbus drives into the mix is going to make things interesting.
The startup sequence for everything is going to be pretty critical...

About twenty years ago I bought a dual tape drive "mass" storage
peripheral from a surplus outfit, United Products in Seattle. It was
for a long defunct personal computer of the '70s. The computer (which
I only ever saw in a few ca. 1978 ads in Byte) was an 8080-based
system, and I think it was billed as having color video graphics
capability. I don't remember the name of the company. Anyway, the
distinguishing characteristic of the system was the tape drive unit
used modified 8-track tape decks. That's right, 8-track *audio*
cartridges, the kind people make so much fun of these days.
The drive was housed in a blue metal enclosure with a black vacu-formed
plastic bezel for the two "drives." It had a DB-25 connector on the
back, though it definitely wasn't a standard RS232 interface. As I
recall, the tape head assembly in each drive had four read/write coils,
and it could move to one of two positions, up or down, thus giving
eight tracks total. Presumably this was to decrease the "seek" time.
I managed to trace through the circuit well enough to figure out how to
write and read back serial data on tape, at about 2400 bps, as I
recall. I had some fun hooking it up to a C64 in the lab to prove the
thing was actually working. I kept threatening a co-worker that I was
going to write a driver for the monstrosity to use on the lab's CP/M
machines. He had just built a Slicer, a 80186 SBC that was popular for
a few years in the mid-eighties, and the thought of such a kludge
horrified him. Heh.
I foolishly sold the dual tape drive and all my notes at a Seattle
Robotics Society auction sometime around 1989. I've done some poking
around on the web recently, but I have found zip about this machine.
Has anyone ever seen one of these tape drives? I actually have a
project that, perversely, requires something like this.

Hello Tony,
I found a request on the internet today but the posting was made over a year
ago. I wish I would have seen it then
because I have this thing that I want to get rid of. It is a KSR33 Teletype
with the interface converted to RS-232.
It is still in working order but probably needs a new ribbon after sitting
for at least 20 Years.
I also have other vintage equipment that used to be connected to the
teletype. It is an old PDP11-05 (DEC).
Let me know if you are interested.
Ken
I've got PC-MOS/386 and wonder if serial port expanders for a 386 or 486 can still be sourced. A hunt of the net opened a minefield of such devices - hoping I can get some help from this list.
TIA!!!!

I have *five* Model 200s now, and not a single one
works, but I have just as many Model 100s, and every
single one works.
Is this just bad luck, or is there something defective
about the design?

Hi
I just saw a request for help in repairing
one of these on alt.folklore.computers. It seems
that this company was actually using this machine.
They are having problems with the printer ( no
wonder ). They are in the LA area. I would suspect
that after getting things printed out, they
might be interested in parting with it ( if they
had any sense ). It would be a good opportunity
for a local collector.
Dwight
Does anyone care to help this person? See below.

It's not "--" but "-- ", and must be immediately preceeded and followed
by a newline. It appears in RFC2646 as a "convention" -- but it's
worth remembering that RFCs are not (mostly) standards either -- just
conventions. There's a document called "son of RFC1036" which is the
basis that almost all modern newsreaders follow, anmd you'll find the
sig separator described in there. "son of RFC1036" was written, mainly
by Henry Spencer, one of the original authors of RFC1036, because there
are some errors/inconsistencies in RFC1036 which needed addressed;
there's also a widely-used document called the GNKSA (Good NetKeeping
Seal of Approval) where it appears as section 15. Both of these were
the result of much discussion on Usenet and appeared because although
the IETF produced many drafts of a successor to RFC1036, none were ever
finalised.

The name was VT50PY, or DISPLY, or something like that.
In V10.1, that program would do ANSI escape sequences if the terminal
appeared to be a VT100 or above (i.e., a scope with XON support and no
fill). But, judging by the sources, that wasn't available before
V10.1. So you can change the code :-) or you can track down an xterm
with VT52 escape support, or you could add it to xterm (VT52 escapes
are pretty simple...)
paul
------------- Ashley's stuff below (pardon me for leaving the
large amount of the previous message up above. I know someone
will scold me for that)
I have VT50PY (yes that's the name) running on my PDP-11. And yes,
that's the program that used to bring the system to its knees on
weaker systems.
I am out of town right now, but in order to make the thing work, you
have to load the BASIC+ source for (I think) DISPLY.BAS and then
APPEND VT50.DPY (or something like that - I'm saying this from
memory and my memory is faulty). Then COMPILE it, and run it. If
you want to allow non-privileged users to run it, compile it to <232>.
It uses the VT50/VT52 escape sequences to clear and update the
screen, so you need to do VT50/VT52 emulation. It does have a
switch to allow you to use 24 line VT52 mode vs the standard 12
line VT50 mode.
I'll check on the details when I get back home. Sounds like you need
to make sure your terminal emulator is doing VT50 or VT52 emulation.
It runs fine on my real VT52s or on my telnet sessions with VT52
emulation.

Vintage Computer Festival 7.0
Saturday, November 6 through Sunday, November 7
Computer History Museum
Mountain VIiew, California
Since the last VCF, the trials and tribulations of daily life made
their inevitability painfully attendant: bills came due, accidents
happened, bad days at the office were had, arguments broke out, and
the morning paper was thrown into the sprinklers yet again. Woe is
us! But lo, a bright and shining beacon of nerdilicious salvation is
on the horizon and draws nigh. The Vintage Computer Festival returns!
Vintage Computer Festival 7.0 is right around the corner, taking place
on November 6-7 at the Computer History Museum in Mountain View in
(still) sunny California. Flights are cheap and so is the admission,
so you have little excuse to stay home cramped behind your computer
trying in vain to craft that perfect Google search term. Just put all
that nonsense behind you and join us for some fanatical Festival
folly!
We are honored to once again have the Computer History Museum as our
sponsor!
And as always, we bring you yet another wonderful line-up of speakers,
exhibitors, and special events, including a 30th anniversary retro-
spective of Maze War, the original "first-person shooter" videogame,
plus so much more!
In fact, we're planning so much for this year's event, it might
possibly be even too much! Some of it we can't even mention yet
because we're still in the middle of planning it. So come on out and
watch us put on a gargantuan geek gala guaranteed to gasify your gall
bladder...either that or watch us crash and burn in spectacular style.
Either way, it's sure to be entertaining!
Exhibitors Wanted!!!
One of the best ways to enjoy the VCF is by participating directly.
Be an exhibitor! As an exhibitor, you get to be a part of all the
behind-the-scenes action. Plus you get a chance to show off your
favorite computer and perhaps even win an award for an outstanding
exhibit. The Best of Show award includes as a prize the Replica 1,
a software compatible re-creation of the legendary Apple-1 computer,
courtesy of its creator, Vince Briel. So don't delay, sign up today!
http://www.vintage.org/2004/main/exhibit.php
More information about Vince Briel's Replica 1 can be found on his
website:
http://home.comcast.net/~vbriel/
