Not yellow, but as you are in the states, try here:
http://www.wncsupply.com/paptape.html
I have a source in the UK for yellow ONE inch tape, and they
can make 11/16 to order, but minimum batch is hundreds if not
thousands of rolls.

Absolutely. Silicon Valley is one of the best places to be for this.
This is where "vswmoretp" on eBay get some of their stuff.
There is a whole used book buying/dealing subculture around the book
sales out here.
Get to know the people at your local library that handle the book sales.
If you are after mags like Datamation, you may need to talk to them
about saving them for you, since they probably would be recycled
otherwise and not even put up for sale, since periodicals don't sell well.

A similar thing happened to me a while ago.
However, my situation was slightly different
in that the seller apologised for losing one
of the items and asked me if I was happy with
the extra items he sent instead.
In your case, if the seller doesn't respond I'd
open up a dispute. If the seller still doesn't
repond then post negative feedback.

As a several boxes of floppy disks slipped and fell, the question occurred ...
if you have a disk with only a vague idea of what computer it might go to, is
there an easy way to find out what computer made it without trying it in a
number of systems? Is Teledisk or Dave's program likely to be useful? And what
about Apple disks?
And to make it "easy", assume the disks all look like soft-sector disks.
Lyle,
It has been a while since you updated the Classiccmp list with the status of
your project to make TSX+ available to hobbyists. Can you tell us where the
project is at the present time?

the only time a totem-pole output would have an issue if it had to fight another output - one low and one high. As long as you are driving using a single output that has to deal with the resistor network, you should be just fine. The interface you are describing is basically the same as on a 8" disk drive.

First off, my apologies to the pdp-8 aficionados on the list. While I used
8's back in the day there's a lot I don't know about them.
I'd like to understand *exactly* what hardware tss/8 needs to run.
My understanding is that it will only run on an 8/I with the following
options
KT08/I timesharing option
MC8/I memory option
KE8/I multiply divide option
I'm curious because I wrote up a simple pdp-8 verilog description which
runs FOCAL and I think it would be fun to run tss/8 also.
I'd like some pointers to documents which describe the options needed and
details about them.
Certainly all of the IF/DF extended memory is needed, since last time I ran
tss/8 we had 32k. I'm guessing that this is covered in the MC8/I documents.
I'm curious if the KE8/I is the same as the EAE.
And I've never seen a description the KT08, all though I can guess what
it does (traps any 6xxx as well as halt and switch register access at
a minimum, but anything else?)
Also, if there is a better list for this sort of question please let me know.
I've never read alt.pdp8.whoknowswhat but maybe I should.

All:
I just came across a Tandy printer (DMP105, 26-1276) and I'm
having problems finding a ribbon for it. The OEM replacement catalog number
is 26-1288 which I believe can be used on the DMP-106, too. I'm wondering if
anyone has knows of a suitable replacement or a consistent source for dot
matrix printer ribbons for "classic" printers. The ribbon itself looks to be
in good condition so I guess I could re-ink it, in which case, what's the
best ink for that?
Thanks.

It is MUCH worse for Burroughs and Univac. IBM was sold in such high numbers
that the probability of some surviving was higher. Both Burroughs and Univac
had an active "scorched earth" policies for systems in the field to keep
them out of the hands of resellers. I don't know of any Burroughs 5xxx/6xxx
systems or Univac 1100's that still exist.
John's Univac III is about the biggest old Univac system that I know of.
There is also a disproportionate number of large scientific computers that
have survived vs business systems. There much fewer in CHM's collection.
I've been selling some stuff on ebay and have found a number of people who

We have plenty of old keyboards which have breaks in the tracks due to

We'll have to differentiate the reproductions from originals in some

Someone from the CHM PDP-1 restoration team contacted Western Numerical

I managed to hack a Western Digital Ethernet card onto my PCjr and I'm pretty
happy about it. Using a packet driver and my own UDP implementation I can get
24KB/sec off of the machine with UDP checksums, and about 39KB/sec with UDP
checksums turned off.
The bad news is that I have a few more of these cards but the twisted pair
connector is designed for LattisNet. LattisNet is a precursor to the standard
Ethernet over twisted pair and it is supposed to be close, but my hubs aren't
buying it.
The cards have AUI adapters and I was lucky enough to have exactly 1 CentreCom
210 which works fine. I need more though - like about 10. They're on eBay,
but buying them onesy-twosy will bankrupt me on shipping.
Does anybody have a few they want to unload, or know of a good seller? Also,
are all AUI/TP tranceivers equal or should I be looking for something better?

So, I'm back to trying to get my 3/180 running again. I'm trying to boot
a SunOS 4.1.1 "for Sun3" install tape that I produced from images and

errors:

The CPU is a 3/180 with 16MB of ram, an Xylogics pertec tape controller
w/ Sun badged Fujitsu M24444 tape attached, and Xylogics SMD disk
controller with a Fujitsu Eagle I think (aka Sun 595-1309).
Anyone have any ideas what I might be doing wrong, or perhaps a working
installer on 9-track tape they could copy for me?

:-) actually, the .sig is a slam at the International Astronomical

"hasn't cleared its neighborhood". I'm working on a spacecraft headed

ObCC: since the hardware will take more than 10 years between
construction and flyby at Pluto, it'll be classic before it's ever

This is a great opportunity to thank everyone on the classic-computer

Fellow Classic Computer Enthusiasts,
I was rewatching "30 Years in the Tardis" last night and came across an item
on the tape I had forgotten about. It's been years since I watched it, and
the last time was long before I started tinkering with classic computer
emulators. Anyway, while rewatching it I was thrilled to come across a
commercial with the Doctor and Romana advertising a Prime computer. I found
some info on the net on the Prime computer line, such as:
http://www.malch.com/prime/
on the net but no mention of an emulator. I also found some manuals on
BitSavers.org. Having been a Doctor Who fan for years, and with Tom Baker
being my favorite Doctor, I'd love to have the opportunity to experience a
computer system he endorsed.

Regarding my switch from an email newsletter to a weblog, there's been a
tremendous about of feedback in support of the old format. Unfortunately
the old format was just too much work for me to keep up with. I would keep
doing it if I had unlimited time and money, but obviously no one does
(except maybe Bill Gates on the money side.)
The good news: I finally got an Atom feed working. The address is
http://www.technologyrewind.com/atom.xml.
Would those of you who prefer email updates be willing to pay a modest fee?
I haven't worked out what technology I will need, but as I said before, I'd
be happy to keep doing an email feed if it were easy and not terribly
time-consuming. This isn't for profit, it's too avoid losing money when I'm
formatting newsletter emails instead of doing real work. (This also is not
any plan to contradict earlier statements about keeping the main product
free -- you have my promise on that.)
Of course, if someone points me to an automated blog-to-email conversion
technology that is SO simple and takes no time at all, then I'll just do it
without any premiums. Or maybe someone can write a cross-platform feed
reader for vintage computers. :)

Hi,
I'm not sure if I've already asked this here, but does anyone
know anything about the Cifer T-5 terminal? Mine is missing the
keyboard so any info on that would help. Otherwise, assuming it's
a fairly typical serial type, it will be a matter of sorting out
the connections and the baud rate - not too difficult but easier
if you know what it _should_ be.

Has anyone here built a gadget to take a UK PAL RF signal as input and output
a US NTSC RF signal (or output something else like composite, which can be
converted fairly easily)? I suspect that a few of the US crowd own UK machines
and may have needed to do this...
I'm thinking that the quickest way might be to homebrew something using a
scrap PC with a UK-spec TV capture card and some sort of video display card
that'll output either composite or to a US TV, but even then I suspect that
there are a few gotchas lurking!

That is the Univac Series 80
The 9000 series is similar but not exactly the same as S360 (a few
instructions and the I/O differ).
There is a complete 9400 that is trying to be brought back to life in

A guy on ebay is selling something that looks suspiciously like the
monitor portion of a terminal, but he is calling it a Hazeltine
'computer'. I asked him if it was a terminal and he responded saying:
"Its a computer, not a monitor."
Either he didn't understand my question (I didn't ask if it was a
monitor, I asked if it was a terminal) or he had a brain-fart and
typed "monitor" instead of terminal in his reply.
The item is #300053801044 and has a detail photo of the model plate
where it says model 1DTD155463. On the lower left rear is what looks
suspiciously like two DB-25 style connectors, presumably one for the
host and one for a printer.
So, did Hazeltine ever make a computer or did they only make terminals?

Another example I can think of is where you have a piece of test
equipment whose operation depends upon software for a computer that is
no longer generally available.
The Biomation CLAS 4000 logic analyzer, for example, is a SCSI device
whose user interface runs on a 68000 Macintosh.
Firmware/software for test equipment is one area in particular that
points out the problem of devices becoming boat anchors because the code
to control them wasn't preserved with the device.
The trend in the past 10 years to produce subscription devices that
depend on a host run by a company that no longer exists (Richochet,
Catapult, Kerbango, ...) is another annoyance.
Hi Henry,
I'm looking for Hardware documentation on rtVAX1000 and found your note on the net. Do you know where can I found such info?
Kind regards,

All true, but partially unconnected and somewhat
oversimplified. Earth's angular momentum vector precesses about the
normal to the ecliptic (the plane of Earth's orbit) in a cone with
half-angle 23.5 (or so) degrees and with a period of 26,000 years.
This is directly driven by the lunar and solar tidal torque on the
equatorial bulge of the Earth, which is in turn caused by the Earth's
rotation. For a rigid body, this could happen without any change in
the location of the "pole" as seen on the surface of the body.
Independent of that (or of any external torque), the point at
which the Earth's angular velocity (not momentum) vector intersects
the surface, which is the instantaneous pole, wanders around on the
surface. This is due to several things. One is the fact that the
angular momentum and angular velocity may not be perfectly aligned.
(Even a rigid body will do this if it is not spun along either its
major or minor principle axis of inertia. This is the "polhode"
motion of a freely rotating body as seen from the body.) Another is
the fact that the Earth is continually rearranging its mass
distribution by rainfall, earthquakes, ice-sheet melting, etc. etc.,
thus moving its principle axes of inertia around and causing the
first condition to apply. (These mass redistributions are in turn
driven primarily by the effects of incoming solar radiation, but this
is an indirect effect of the sun on the system.) Another cause is due
to the fact that the "solid" Earth is really a composite system, with
many different solid and liquid components, many of which may be
rotating with respect to one another and causing various interactions.
I think I will stop there, acknowledging that I'm still
oversimplifying.
I will however add that I at one point in the early 1980's
wrote a program in Fortran on a PDP-11 to display the current and
predicted (by the IERS) Earth instantaneous pole coordinates on a
Tektronix 4025 graphics terminal, erasing and re-drawing the
predicted pole with every new update of the current pole. It was
interesting to see how consistently off the predictions were.
Sorry for the delayed-gratification nature of this post; I'm
just getting back from 2 weeks' vacation.

The Atari Jaguar is basically a Super Spectrum
(SS).
No I'm not kidding (surely someone here can
back me up?). There is a page on the web
somewhere explaining how the guys that were
designing the SS ended up working for Atari.

Also, with the CD unit fitted into the Jaguar

All:
Here's an interesting one. I have several disk images for the
Tandy 2000 that had been made with TeleDisk. One of the images is bad for
some reason (must be truncated; won't get past track 30; complains that
target disk drive is not ready when it reaches T30). The original disk is
not available.
I've done the basic troubleshooting on the drive and media
(other images made with same new floppy diskette and drive work fine;
swapped drive and media) to eliminate them from the failure tree.
Even though TeleDisk seems to write to track 30 just fine, the
disk is unusable. This is odd because it's an MS-DOS format (although 80T
9S) so all of the directory and media parameter info is at the front of the
disk rather than the back.
Is there anything I can do with this partial disk image to
retrieve at least some of the info?

Actually, a bad example, since sources are available.
This is a worthwhile effort, but very time consuming.

Hand-disassembly is just the start. Vast machineries of
automated disassembly/decompilation is used
throughout the world in piracy and reverse-engineering
activities. These sorts of tools have been in existence
for at least 30 years, very likely 40 or 50 years.
Related to these machinations are other tools used
in reverse-engineering, including emulators, simulators,
in-circuit emulators, logic analyzers, etc.
All of these tools are also used in retro-computing
as defined by many different groups: video gamers,
emulation of historically important systems by academics,
and everything in between.
But what you describe goes way beyond simple archiving,
and more into the tools that let you analyze and
appreciate the code. If you can combine the code with
the original designers, original users, original
business documents, etc., then you are really on the
road to a complete recreation of not only the code,
but the world at the time.
As a classic example, 25 years ago you could buy a tool
that disassembled your CP/M binaries and turned them
into *commented* sources. Not the original source, of
course!
Tim.
Has anyone considered decompilation (producing sources from binaries)
as a way of archiving system or application software that is defunct?
I know lots of people have disassembled ROM listings and created
commented ASM listings from the ROM, but what about larger systems
where hand-disassembly is impractical?

My recent post re BBM manuals has left me with a bit of a
dilemma; I've got several more boxes of various manuals etc.
to dispose of and I'm not sure what's the best way.
On the one hand, it benefits everyone to have them in Al's
hands, who has the means, time and willingness (thanks, Al)
to make them available to us all.
On the other hand, anyone who actually owns the relevant
equipment would probably like to have original documentation.
When I put them up on the list, I'm inevitably going to disappoint
someone; should I just offer it privately to Al and rely on him, or?

you can do very well copying manuals and such with a

Random thought of the day....
I've seen a few CDs around where the manufacturer has deliberately included
errors on the disc to make piracy more difficult - which is a noble enough
thing to do, but a bit of a pain in the butt when you want to make a
legitimate backup copy of a disc :-(
Has anyone come across tools (Linux preferred, but I could stomach Windows if
I had to!) which can duplicate such discs and produce errors in the output at
the same block as the input? (I assume any software on such
deliberately-crippled media would check for the presence of known errors at
install / run time)

Mothers Day ..... how did I not realize that????
That leaves June 2/3 and 9/10. If we choose 9/10 then we give people a weekend off after Memorial Day.
But would there be more conflicts with graduations (on either of the June weekends) than with the Dayton event?
I know all about the "you can't please everyone all the time" rule but we're still trying.
All:
For those who might not have been aware, Steve Wozniak was in New York
last night for a book signing at a Barnes & Noble. I attended this
signing and I thought I'd provide a book report of sorts for those who
haven't yet been (the last one was in Philadelphia about a month ago).
I arrived not knowing what to expect and there were only about 25 people
in the gallery at 5:30 (the presentation began at 7pm). This event was
competing with the Christmas tree lighting at Rockefeller Center, so I
figured, hey, it shouldn't be too crowded. Yeah, right.
While I was waiting, I grabbed a copy of iWoz and began reading. My
report on the book itself is at the end.
There were about 150 seats and by 7pm, 175 people were there. I'd say
about 80/20 male/female ratio, from a 9 year old girl with a cello
strapped to her back to about 55. Ethnically, it was a pretty diverse
crowd.
Steve arrived on-time and after a short intro, began his speech. I don't
think he stopped to breathe. He spoke constantly for 45 minutes. In
spite of his stated shyness, he was a very gracious and engaging
speaker. You can tell that his mind is running far ahead of his mouth.
Yet, in his speech, you can hear a boyish quality that conveys such
excitement about computers and amazement as how he, as the "other Steve"
with the engineering brains, created the first color personal computer
that could be connected to the TV, and, by his accounts, lit the rocket
on the nascent personal computing industry (I think he actually said
something like "how we started the industry").
I bet that if the guy from Barnes & Noble didn't keep him to a clock, he
would have told stories until closing at 10pm.
I spent only a few minutes with Woz. He signed my Woz book, an original
instruction manual from my Apple II (which he pawed over, not having
seen one in years), and we talked momentarily about my Altair Emulator
project. There were people there who brought old computers for him to
sign (which he did). Most people just had their books signed.
Now, onto the book itself. While I was waiting for the presentation to
start, I began reading around the middle of the book and in an hour and
20 minutes time, read almost 100 pages. The book is an easy read and is
in a conversational style that after hearing Woz speak, one can easily
see how the book was created...he told the stories and Gina Smith, the
co-author, wrote them down, preserving his familiar, conversational
style. This isn't fine literature, and Steve readily admitted that he's
not much of an author. But, if you think of it more as you and Steve
sitting at a bar talking about old times, you will enjoy it.
Since I began in the middle at a random spot, I didn't read about
Steve's early years. He did allude to his childhood in his presentation,
and this is where most people will discover the "I didn't know that."
facts about Woz.
I picked-up the story around the time of Steve creating the Breakout
game for Atari. The back-half of the book is filled with common Woz
stories about Breakout, the 500 machine purchase from The Byte Shop, his
drive for elegance in design (and reduced parts count), and hacking a
Shugart floppy drive to make a very elegant floppy controller system.
There were some brief mentions of fights with Jobs, like over the number
of slots to put in the Apple ][ and the failure of the Apple ///, but
any disagreements with the other Steve were treated gingerly.
I'm sure there are kernels of rare or never-heard Woz stories in there,
but in the pages I read, I didn't really see any.

SH1 was the CD controller? I thought it handled
the sprites?
The SH2's handled the polygon output (250,000
each) of 500,000 polygons per second.
The board was nicknamed the "Titan" board
and was still used well into the late 90's
despite being superceded graphically by all
of Sega's Model 1 & 2 boards (and Model 3
board in 1998/9).
However, due to it's mastery of 2D and 3D
it was used on many arcade games (sorry,
can't name any now, been too long since I
last spoke about this board).

Hey everyone,
I've been in touch with someone on the East Coast (of the U.S.) who has about
ten DECstation 3100s, a few DECstation 5000/200s, and some Sun 3/50s and 3/60s
available for the cost of shipping. He just doesn't want them to end up in a
landfill.
I've snagged two DECstation 3100s and two DECstation 5000s, but that's about
all I can do right now. If anyone is interested in any of the remaining stuff,
please contact me off-list and I will forward your contact information to him.

What about an IBM XT with a Big Blue CP/M Card, AND a Trackstar 128 AND
a Hydra (MacPlus) board?
Wouldn't that give you 4 processors in one machine?
One could also run an Amiga with an 8088 Bridge board for dual processors.
Or, an Apple IIe, IIgs with a Transwarp card for two processors? Three
if it has a Microsoft Softcard...
Which makes me think of the Zip Chip and Rocket Chip for the Apple
IIe/IIgs series.
Did these chips also work in the C64 and other 6502 machines?
I remember working with them, but don't have one for either of my IIgs
machines...
I *DO* have an Orange PC card that will turn a PCI Mac into a PC. But, I
don't have the required cable or software for it. So, it's merely a
curiosity at this time.
That would make a Mac a Dual Processor machine, wouldn't it?

They can be regular dumb terminals or "layers" terminals, which is a really
rather interesting, pre-XTerminal remote windowing system worked on by,
among other luminaries, Rob Pike. As I recall, they came out with an X
cartridge for the 730 since layers never caught on. I only saw NCR rebadged
X Terminals during my time at AT&T, so I assume the X cartridge didn't catch
on either, even internally.

Don't think many of them ever made it out of AT&T...at least I've never seen
one in the wild.

Apparently not, at least for some of the Eastern Bloc clones; see
http://hampage.hu/tpa/e_index.html. For the Hungarian machines, cards were
definitely physically different, I'm betting things like power supplies are
local creations and anything using LSI (F-11 clones, for example) were
undoubtedly somewhat original due to differences in the manufacturing
processes the Soviets had access to (and DEC never made anything that looked
like a K1801VM1).
Very faithful clones as far as the software was concerned, though.
If you can find a Hauppauge 4860, you get an i486 and an i860. Toss in a
DAC960E EISA Raid controller and you get an i960. And an NE3200 EISA
network card, and get an i80186. Add a National Instruments AT-DSP2200
EISA data acquisition card, and you get an AT&T DSP32C. Add a A Hercules
Graphics Station card and get a ti34010. Add an Opus card or two and get
more (mc88100? SPARC?).
That's 8 processors, 6 of which are directly available for fiddling.
I've had, at one time or another, all these cards, but since I never put
them together, I guess I don't win.
Ha ha, I knew you you'd read it!
Actually, I'm testing Yahoo's delivery.

How easy is it to take the plastic (?) keys
off of a keyboard without damaging either
the keys or the contacts underneath?
I assume, if they are taken off without
damage to them, they would simple clip back on?
I have never taken a keyboard apart yet, and
will no doubt need to someday. I probably won't
bother until a keyboard, or keys, starts failing.

While attempting to restore some files from a 4mm tape, using an HP
SureStore Tape 2000 drive, something happened to me for the first
time: the drive made a strange moaning sound then stopped reading the
tape. Not only did the drive stop reading the tape, but it had begun
eating the tape as well, nearly chewing all the way through it on one
spot.
I'm guessing that this is a problem which, if not affecting others
yet, will soon start affecting others who are relying upon such drives
for backing up and restoring critical data. Fortunately, I'd recently
switched to using DLT IV drives for backups, but a few files that I
wanted to restore were still on other tapes.
Does anyone know where rubber parts for these drives, like rollers,
can can be purchased, so that others with these drives can replace
them and avoid what I experienced? I should have realized that
something was about to go wrong with internal parts as well when one
of the drive's rubber feet began to stick to the metal chassis it was
resting upon.

I've been poking around inside my HP9000/C180 machine (1x SE Fast-10 narrow SCSI, 1x FWD integrated, 1x FWD GSC card).
I am aware that this machine is still slightly stretching ontopic, but the diff part is definitely ontopic.
Currently, it has 1x4GB and 1x2GB, which leaves little free space with a very off-topic OS (HP-UX 11.11)
diff SCSI drives, while technically superior to SE, are difficult to find, so I'm looking at alternates.
Looking at the machine, the SCSI busses appear to have a standard SCSI chip feeding into differential
drivers. Is it possible to gracefully remove the diff drivers and convert it to single-ended operation?
Quoth Zane:
>Have you thought about getting converter boards to convert SE drives

I've got a DEC DWZZB converter, but that requires messing with the
StorageWorks shelf and cables to trip over and set up every time I use the machine.
I also have a pile of SE drives, including 1 9GB. Diffs seem to be most common in the
4G and under range, and all bays are full.
It also seemed like a reasonable way to make an old machine more useable without
spending money, pulling a couple of driver chips and putting in jumpers- but perhaps
not. Maybe NFS is a better answer.

Decomposing rubber components has been a problem for digital tape transports
for at least a decade or more now. I know of no vendor who supplies
replacements for the dozens of different QIC transports, for example.
Crisis Computer used to fix HP transports, but they do not sell parts, only
expensive refurbed complete units.
This should be a business opportunity for someone, but I don't know of
anyone who is selling replacement rubber parts for digital transports.
Anyone who has historically significant data on tape should get it OFF of
that media as quickly as possible and onto something that is more easy to

Hi all,
This isn't official yet, but we're aiming for Saturday, May 19 next year.
We might add Sunday, May 20 as well, but that won't be decided anytime soon.
Location is the same as East 3.0 was this year: the InfoAge Science Center
(infoage.org) in Wall Township, N.J.
We considered having the East event on the same weekend as VCF Europa, and
having inter-VCF things such as IRC terminals and videocasts, but
unfortunately it didn't work out because of some other BIG news that I can't
announce right now but might within a couple of weeks. :-)

Hmm, there are indeed some smaller components I hadn't noticed that might indeed be memory, Some smaller unbranded 2x HC240's, 4x HC74's and some rather large ones : Malaysia 8835/ HM6264ALFP-12T.
I'm still not sure I'm following, whilst you are probably giving me usefull information. My knowledge on the pure details of a harddisk are fairly limited. I know how it mechanically works, but how the data is carried is another thing. What does this mean: "From the OMTI chips you mention, I am now almost certain that's a raw interface, possibly simular to ST412."
Could I use the 50 pins connection from the motherboard to the board for any other purpose ? Is any 26 pin HD in 3,5 inch available? What are my options? The original 26pin harddrive is dead, the step-motor to rotate the hard discs is fried. (Btw, the original HD takes its power from the datastrip).
Thanx & Greetz Stijn
I have someone looking for up to 4 BA11F expansion boxes with or without
cabinets or power supplies. If you have any please contact me off list.
Thanks
Paul

Would it be possible to extract the roller and clean it, then use
multiple
layers of inner tube to make it up to the right thickness? Use an
adhesive
to stick the layers together and to the metal roller otherwise they will
work themselves up toward one end. Inner tubes are available in a
wide range of sizes from bicycles, trade bikes (mountain these days?),
motorcycles, cars, lorries and tractors and they can be stretched a lot.

Found it. Yes Tony was right.

Funny that HP came out with an 80286 PC compatible
before their 8086 based PC.

According to the HP9000 Series 300 Technical Data booklet (Feb 88,
5951-6785, from www.hpmuseum.net), at that time HP had two Vectra models in
the Series 300 lineup:
* PC-305, HP Vectra CS PC (8086)
* PC-308, HP Vectra ES/12 PC (80286)
Each contained the HP BASIC Language Processor board with a Motorola
68000 at 8MHz, 512 K RAM (expandable), BASIC 5.0 in ROM (or Pascal 3.2 on
floppy), and HP-IB & DIO interfaces.
The museum has more info on these and other Vectras.

Does anyone have the TUK50 (M7547) maintenance print set or a scan?
Not the TK50 drive print set, the real Unibus interface for the TK50.
I'd like to get a copy.
Thanks,
John
Anyone know anything about these?
Apparently they could be used as X terminals and they are essentially
diskless workstations with a 68000 inside.
There is some stuff in Richard Shuford's usenet post terminal
archives, but not much else I've seen around.
Any AT&T 3B2 owners out there have one of these in a working state?
