I have bought them. These are the very same diagnostics I wrote about on this
list just a short while ago when discussing poor man's alternatives to AXE for
validating new VAX implementations until we can raise enough manpower and
firepower to storm into HP headquarters and seize AXE at gunpoint. These diags
are not specific to 730, I read about them first in an 8200 manual and they test
for correct operation of standard VAX instructions. I understand from the
discussion on this list that their coverage is nowhere near as complete as AXE,
but it's still a more complete test than just seeing my new VAX boot
4.3BSD-Quasijarus. (For example, UNIX makes absolutely no use of executive or
supervisor modes, just kernel and user.)
The next challenge will be reading the TU58s. I have the TU58 mechanical units,
but not the controller board (the board that talks serial on one side and drives
the head coils on the other). So I'll need to find a controller board first
before I can read them. When I do read them, I'll post the block images on my
FTP site.

Went to a school auction and picked up the following:
HP 3000 model 922LX
HP tape drive 7980
2-IBM 5291 Display stations with a maintenance library manual
Dictaphone system model 6110 with KB model 6301, printer 6710, and ext. FD
(51/4) model 6430
All for $10
I think I may have heard someone mention, perhaps in private email, that the
HP3000 was a popular replacement for HP2000 TimeShared BASIC systems. Is
this true? Did it have multiuser BASIC? Any other languages? Did you have a
choice of different OS's on the same hardware? And more importantly, did any
of the 3000's have blinkenlights? :) I know nothing about the 3000 stuff.
Curiousity biting me :)

G'Mornin' Dan;
I saw an ancient post of yours "I recently bought a model 1220 analyzer on eBay which is very similar to the..."
and I find myself in a similar situation: proud owner of a $25 1230 with no pods or probes; wondering if you made any progress in your quest and fantasizing that you may happen to have for sale just what I need.
Any suggestions appreciated :)

Frank will probably give a much better description when he sees this, but
the 3000s built in the 70's had pretty impressive maintenance panels (I
know Frank has one of them..)
MPE was (is) the only operating system. Languages included BASIC, APL, FORTRAN
PASCAL and SPL. There was no assembler. It is a stack machine ala B5xxx series.
I have been scanning a LOT of 3000 material (mostly through the Series III) and
I'm trying to locate distribution tapes from these machines up through MPE IV
(early 80's)
>From what I have found so far, there was a lot of documenation from these early
3000s saved, but none of the old software distributions.
I'll see about getting some docs/pictures up on bitsavers, which is pretty light
on 3000 material right now.

also, bitsavers moved yesterday to a new machine/ip adr which should be transparent

Anybody want a few HP workstations?
I have a few 9000/735's (two of which should be working)
and a bunch of 9000/c110 machines (stripped, no memory,
no drives).
I also have an IBM monitor that will work with the 735's.
Free to a good home, the only catch is that you'll have to pick
them up from Wichita, KS. I'd like to dispose of the entire lot
in one go if I can.
Otherwise, they'll be melted.

Michel Bel in France often has broken/part LX's for sale. You can contact
him through the HPLX mailing list
(http://www.sp.uconn.edu/~mchem1/HPLX.shtml).
You will probably have trouble finding a 200LX for $50, though, since for
$125 you can get a broken one (even a broken LCD) fixed at Thadeus and
working ones are going for $150+ on eBay now. The average prices are down a
bit now from a year ago. If you are patient, you can get one for <$150. I
paid about $115 for mine a few years ago, when the average price was more
like $300.

Does anyone have an extra working/possibly repairable 200LX laying around,
that
they would be willing to part with for $50 or less? They seem to be selling
for
far too much on e-bay. I don't really need any of the extra things that are
included in all these auctions, memory cards, adapters for this and that,
modems, or manuals. I would just like the unit. Thanks in advance for any

anyone can provide.

That pretty much sums it up. I have a need for a keyboard and mouse for
an Apollo DN300. It seems to have some sort of RJ11-type connector for
the keyboard. The mouse probably plugs into the keyboard.
Note that this does NOT seem to be the newer Apollo DOMAIN keyboard
with the DIN-type connector.
Hopefully somebody out there can help.

Anyone have experience with the +15v regulator buried deep inside the
back of a BA11? (this an 11/34a actually)
It appears one let go on me this morning. The symptom initial symptom
was no +15/-15v, so I went to my garage and pulled the two supplies from
a "spare" BA11. I replaced them and got the -5 and +20 back but no +15.
I should have known it would be the supply deepest inside the back of
the thing, requiring I completely disconnect the back module. blah.
Is it hard to get to and replace? I'm tempted just to swap the back
ends of the two BA11's...

They came back to retreive Richie Lary
I have just met an ex-DECer in the #ufo channel on the Undernet IRC network who
claims to have seen UFOs over DEC. Needless to say, I was extremely intrigued,
being both a ufologist and a great DEC fan, and I asked him for more. He told
me it was in Colorado Springs around 1993-94. He said he couldn't remember the
3-character DEC facility code, but he said they were working on CD-ROMs there in
a clean room when CD-ROMs were state of the art. He said the facility still
exists today and has high security. I asked him if it went to HP and he said
Quantum. So I immediately thought DLT and asked him if it was the facility
where they made DLTs. He said yes. He said he worked on the tape drives
himself, as well as on CD-ROMs.
Now here are my questions for this list, to verify the story and to fill in
missing details.
* Were DLTs indeed made in Colorado Springs? DEC's tape business went to
Quantum, didn't it? Did it go through Compaq or straight to Quantum from DEC?
Does Quantum still own it? Or did HP snarf it from Quantum? I once visited
Quantum in 2002 for a job interview (they were looking for someone to write
firmware for a RAID array to emulate a tape library) and that was in Irvine, CA
on the UCI campus. Is it just the headquarters, with actual DLT tape drive
manufacturing in Colorado Springs?
* If it is indeed in Colorado Springs, does anyone have any more information on
that ex-DEC facility? Does anyone know of any government/CSS work done there?
* This guy also mentioned CD-ROMs. He said they made the first DEC CD-ROMs
there, in 1993-94 timeframe. I thought the first CD-ROM sold by DEC was RRD40
and was actually a Philips drive, wasn't it? The next was RRD42, which was
actually made by Sony, right? Did DEC ever build CD-ROM drives themselves or
did they all outsourced to Sony and such? If RRD40 and RRD42 were Philips/Sony,
why did they need a clean room in Colorado Springs? Or was it the next one,
RRD43? Was RRD43 also Sony or was it made by DEC itself? What was DEC's
cutting edge CD-ROM drive in 1993-94? Did they make any CD-ROM drives at the
same place where they made DLTs? It kinda makes sense that it would be the same
group, "Tape and Optical Products" if I'm not mistaken, but just checking.
Here are the relevant parts of my conversation with this guy from my IRC log:
<VortexQ:#ufo> there were about 50 people that saw this on a clear blue day...during lunch
<VortexQ:#ufo> <VortexQ> to everyone's surprise...we all looked up and a huge cigar-shaped UFO was hovering over the building at about 200 feet overhead
<VortexQ:#ufo> <VortexQ> right over Digital
<VortexQ:#ufo> it was very apparent that there seems to be a vested interesting from a higher source, in DEC
<VortexQ:#ufo> interest, that is
#ufo> VortexQ you still didn't say which DEC facility/group and when did it happen
<RB2:#ufo> Msokolov> Colorado Springs
#ufo> RB2 what do you mean? You mean DEC facility in Colorado Springs?
#ufo> what time period? how long ago was it?
<RB2:#ufo> That's what I understood from Vortex
<RB2:#ufo> I have no idea, he didn't get to that yet :)
#ufo> did he tell you what was his job at DEC?
<RB2:#ufo> No, I didn't get anymore information than that.
#ufo> I still wonder when did it happen
#ufo> RB2 said it was in Colorado Springs, wasn't it? Can you tell me the DEC facility code? I know each DEC facility has a 3-letter code
<VortexQ:#ufo> F***...what is the code?
<VortexQ:#ufo> hmmm
<VortexQ:#ufo> it has been a while
#ufo> did you actually work at DEC?
<VortexQ:#ufo> yes
<VortexQ:#ufo> doi
<VortexQ:#ufo> like people remember the stupid facility code for the rest of their lives...sheesh!
<VortexQ:#ufo> I do not work there anymore
<VortexQ:#ufo> duh
#ufo> how long ago was it?
<VortexQ:#ufo> well, hell
<VortexQ:#ufo> they were working on cd roms in the clean rooms at the time
#ufo> their computer technology was so marvelous that even aliens got interested!
<VortexQ:#ufo> cd roms were fairly cutting edge back then
<VortexQ:#ufo> I think the aliens were more interested in the research they had going on in the basement...Msokolov
<VortexQ:#ufo> 1993-1994...somewhere around that time
#ufo> thanks VortexQ, that's a much better date
#ufo> more precise than "when making CD-ROMs"
<VortexQ:#ufo> well, I have the flu...Msokolov...my thinking is a bit slow between tissues
#ufo> VortexQ, I know the feeling, I hate flu too
<VortexQ:#ufo> in fact...strange that you meantion them being shut down
#ufo> why strange?
<VortexQ:#ufo> I do not really believe they are...Mskovolov
#ufo> well DEC was torn to bits and sold off to various nuts like Comfuq/HP
#ufo> VAX was killed and buried
<VortexQ:#ufo> after the craft started showing up...the whole facility seems to be very off limits secure now
<VortexQ:#ufo> yeah...true
#ufo> does it belong to HP now? that facility you worked in
<VortexQ:#ufo> yes, I believe so...Quantum had it
#ufo> so it didn't go with the rest of Digital to Compaq? It went to Quantum instead?
#ufo> VortexQ, was it the facility where they made DLT tapes?
#ufo> I know that part went to Quantum
<VortexQ:#ufo> yes, Msokolov...why?
<Shambuku:#ufo> Vortex do you have a degree ?
<VortexQ:#ufo> no, I do not have a degree
<VortexQ:#ufo> why?
#ufo> I'm tracking it down, this may be of extreme importance to humanity
<VortexQ:#ufo> is it necessary in order to be intelligent?
<Shambuku:#ufo> Then how did you get a job at DEC
<Shambuku:#ufo> Yes
#ufo> you don't need a degree to be intelligent
<Shambuku:#ufo> Yes you do
#ufo> only to satisfy the assholes in HR department
<VortexQ:#ufo> I have a year in electronics in college
<VortexQ:#ufo> you could say I learn very quickly
<nwb:#ufo> did einstein have a degree
<VortexQ:#ufo> lol
<Shambuku:#ufo> Yes
<VortexQ:#ufo> about that too Msokolov
<VortexQ:#ufo> I worked on the tape drives...I also worked in the clean room on cd rom drives...the very first ones going out
#ufo> what CD-ROM drive was that? I thought both RRD40 and RRD42 were built outside and only badged by DEC
<VortexQ:#ufo> the tape drives are used to backup data on the system...used as a backup for the server data
#ufo> I know of course what tape drives are for
#ufo> I'm a real geek of BIG computers, still run VAXen
<VortexQ:#ufo> I have also worked as a computer operator in a computer room at a hospital...doing backups and monitoring of the servers and also micro fiche
#ufo> cool
#ufo> but still, what CD-ROM was it that they were building themselves in a clean room?
#ufo> I thought RRD40 was Philips and RRD42 was Sony
<VortexQ:#ufo> guess what, they left me all by myself and I had no problem at all handling the entire list of tasks
<VortexQ:#ufo> the manager just hands me the list...shows me around and says...can you handle it? I said yes.
#ufo> so what was the first CD-ROM drive built inside DEC itself? Was it RRD43? Or am I missing something?
<VortexQ:#ufo> and I did it
<VortexQ:#ufo> hell, I would have to dig out boxes for that information at this point
<VortexQ:#ufo> I am more interested in holographic computer systems and crystalline data crystals at this point in time
<VortexQ:#ufo> you'd be surprised what things are going on now
That's all I have gleaned from this guy. I don't expect much help from this
list with the UFO part, but at least I'm hoping someone can chime in on the
parts having to do with the history of DEC and whatever Classic computing
technology they were working on that was so marvelous that even the aliens got
interested in it.

P.S. A more complete IRC log is available on request.
I found a Pinnacle Apex optical drive but don't have any disks for it.
Does anyone have one they'll loan or sell me so that I can try this thing out?
Joe
I went by a surplus store today and found two interesting disk drives
made by IEM of Ft. Collins, Co. The first drive is a Series 5300 (model
5365) and appears to be an MO drive. It has a HP-IB interface.
The second drive is a series 6000 (model 6050). It has four drive
indicator lights on the front so it may have four fixed drives in it.
There's also an LCD display on the front and three buttons labeled "Prev",
"Select", "Next". It appears to have both a HP-IB interface and a SCSI
interface!
Does anyone know anything about these drives or what media the first one
uses or what the dip switchs on them do? I searched the net for IEM and
found plenty of references to them but the link to their site is dead. The
links referred to them as a thrid party supplier of HP drives but didn't
give any details.

It's sort of on-topic because it relates to HPEMU :)
I've run into a few snags when trying to GNU-ize HPEMU. Specifically my lack
of knowledge revolves around dynamic (dlopen-able) libraries. I've googled

want by directly calling ld and it works fine, but I don't see exactly how
to make that fit into the GNU way of doing things. If anyone is up on

All,
Round Tuits are in short supply around here. However my wife
(after *two years* of patiently waiting) finally started shopping for
printers, motivating me (it's not the money, it's the pride) to
finish the repair I'd started on the Apple Stylewriter I was whining
about on the list in January 2002.
Success! I dug out the packet of 2SB1243 transistors (thanks
Pete Turnbull for specs and identification) that arrived in the mail
a few days after motivation disappeared in 2002, tested them to make
sure the Base was the same place on the new package style (not the
same beveled edge square package as the originals) as it was on the
old package style (thanks Tony D. for telling how to test with analog
VOM), and soldered them in. Put everything back together (thanks
JPero, Toth, and Matt for help there and suggestions on other things
to check) and plugged in the new (replaces the one I fried while
testing - thanks Saint Don Maslin) power supply. No response. Changed
to the other Stylewriter (won't print, but powers up) that I got from
Electronics Plus (thanks Cindy Croxton). Powered up, didn't print.
Changed back. The original one powered up and printed! The power
supply connector is grungy, need to clean it, but otherwise the unit
appears functional! That implies that the power transistor was indeed
the problem all along.
Main point of this message is to offer sincere gratitude to
all the folks that helped me along the way!
Secondarily, if anyone has the same fault (missing line of
dots in the printed output from a Stylewriter), I'll be happy to pass
along my experience, FWIW.
Tertiarily, I'm angling for the honor of the longest
(chronologically) continued thread on the list ;-).

>Do you think people misconstrued the model number as the serial number? The

>Woz. Or is that myth?
I don't know about Jobs and Woz signing early ones. In fact, I tend to
doubt it is true, as to the best of my knowledge, Woz had nothing to do
with the 128k. (There are IIgs machines with Woz's signature)
ALL early macs have the development team's signatures inside the case.
Jobs is among those, but I do not believe Woz's is there (I'm not 100%
sure).
I regularly see people trying to play up the signatures inside the case
as some rare thing that is worth money. In fact, what might be worth
money, is a case that truely had NO signatures inside it, because those
don't appear to exist (not counting those that the mold did a poor job of
reproducing the sigs, I have one like that, the sigs are very hard to
see, but they are still there).
And going back to the ebay auction, it strikes me as REALLY REALLY high
to pay $411 pounds for a 128k with no documentation or softare, cracks in
the floppy case, a broken/sticky keyboard, and not fully tested.

I'm looking for two items to get a couple of machines back in operation.
First, I have a Heathkit H-17 drive with a broken fuse holder (the black
plastic tube with the red button on the end) that I'd like to replace.
I can obviously bypass, solder the fuse in-line or use any old holder,
but I'd like a "correct" replacement. Does anyone have a source for
these? A part number would also help.
The other item I have is a DEC Rainbow with a busted power switch. The
switch a fairly typical wide rocker style in gray plastic with a 1 and a
0 printed on it. Again, I can replace it but I'd like a "correct" part
if anyone has a source, part number or spare.
Thanks in advance!

Hello all,
I have a Data I/O 280 programmer, and I had an old copy of Promlink 2.7 that
I used to control it (someone emailed me a copy). I lost the files, and a
search of my old email archives came up short. Can anyone .ZIP and email me
that specific version? Data I/O no longer supports the 280, and the later
versions of Promlink dropped support for the 280....
Thanks!
Rich B.
CPUs could have emulated guts, either software or one off hardware
designs, with replica enclosures and front panels. That feels like it
would result in a reasonable result for the effort required, but
mechanical I/O will be the tough bit. I have recently mulled over the
idea of constructing a PDP-11/04 replica; I imaged a bent metal case, a
replica programmer's front panel, and an internal PC mother board
running SIMH would be feasible, but I have shuddered at the thought of
trying to interface it to 8" floppy drives (if I could find any), or
building a card reader and line printer.
BTW: What is the origin of this message? I cannot find it in my mail
archive.

actually, the usual switches these days on PC computers are only
logic switches back to the power supply. The power supply does
"tap into" the ac line to get a little power it needs.
My P4 that I built last year uses an ANTEC case and there is
no AC going out to a front panel switch - it is only a push button.
A good rule of thumb is that if a switch clicks then it probably
has AC on it. If it doesn't then it MIGHT be only low voltage.
As an electrical engineer, I would not take the chance and assume
it is low voltage without checking.
Any computer that is pre-ATX will have AC voltage on the power
switch. Some early ATX and maybe even now (I don't know for sure)
may still have a real switch out front.
The older mini-tower systems that have a power switch out front
usually had a AC connector on the back of the power supply and
a four conductor cable that ran out to the power switch. The
power could tap into the AC line without affecting the switch
out front.
The older NEC, etc systems sometimes had a seperate power suply
with an AC connector and cables, etc that were not integrated
into the power supply like the PC, AT, ATX supplies that came
along.

Hi,
I've got a generic PC/XT 8088 clone (contains NEC processor) with no HDD
and two 5.25" FDD. Needless to say that the media as well as the O/S (M$
DOS) is not available in my local market. I was wondering if it's
possible to:
(1) Install a 3.5" 1.44MB FDD in it.
(2) Acquire FREEDOS and boot the machine
(3) Use some sort of DOS terminal program to connect to a Linux machine
Appreciate any help and guidance.
Thanks.

Hi folks,
I think I posted this on here first but I'm not sure :)
Anyway, (slight OT drift here) my '97 vintage 21" PCXAV monitor (the one
with the paper-white case & trinitron screen) has decided to start
flickering and dimming itself. Lee's already given me a couple of pointers
but I thought I'd ask here too in case he's not about.
I've got the PSU here and there's a couple of things on there that make me
worried:
http://www.wowrarelook.co.uk/resistors.jpghttp://www.wowrarelook.co.uk/burnt.jpghttp://www.wowrarelook.co.uk/solder.jpghttp://www.wowrarelook.co.uk/solderside.jpg
The middle 2 are the front and back of the same components on the board.
Should I be worried that so much solder is escaping/has escaped from the
joints? Also the soldering in 'solder.jpg' looks decidedly iffy. I haven't
checked the resistors yet to see if they've failed.....is it normal for them
to get so hot they burn the board?
Probably more pix to come when I get the logic board out :oD
cheers

Before you junk the Classics, open them and pull the RAM card if it is
present. They are getting harder to find and you should be able to sell
them.

Patent?!?! We won't honor no fucking patents! I'm the reincarnated Karl Marx!
My new VAX will be completely open source hardware: I'll open-source the Verilog
code. There will be no problem with fabbing it right there on Mars.

I'm sorry to inform you, but your title to that land is invalid. The same goes
for everyone selling and buying land on Moon and Mars. That land belongs to the
Galactic Federation. The Federation will give that land for free to any
refugees from Earth fleeing from capitalism and seeking to live a completely
egalitarian society without money or property, but if you start claiming
property, we won't respect your claims any more than we respected the feudal
landlords of czarist Russia we overthrew in 1917.

Hi I've been searching on the web for a power cord for my ATC-510. I ran
across something saying you found one or found a place where you could find one.
I know it was a couple of years ago that you posted the message. Any help I
could get would be appreciated.
Thanks,

Yes, you can, except that for UNIX systems like 4.3BSD-Quasijarus it's magtape

With the initial FPGA implementation this will be problematic since all FPGAs
that I know of (sufficiently large ones anyway) come only in those damn BGA
packages. But if/when we can fab a real chip, I would definitely use a more
hacker-friendly package if the package choice were up to me.

That's a tough one too, though I have heard that making the required Class 100
clean room is not that hard.

Well, as Ethan pointed out, the 730 used an 8085, so I don't really see a
problem with using a Z80 or even an 8086 (hey, before everyone attacks me, it
ain't a Pentium, and it *is* of the right age).

Look, that was meant to be tongue in cheek! I can't imagine how could someone

Hi Dwight,
I'll keep you and everyone else who has responded informed on whatever
material I am able to collect.
Btw, I've got scads of 8080 software that I wrote for my Altair which
could be easily ported to the H8 if anyone is interested - Including my
own disk operating system, BASIC interpreter and even a C compiler -
The OS was originally run on a NorthStar 10 sector hard sectored disk
system which is probably not that different from the Heathkit one.
I don't have a disk system for my H8 :-( .. if anyone knows of one or
comes across one, I'd like to hear about it.
Regards,

I'm located out in the country with only dial-up access, and the Franklin "package"
is over 100 megs - I'll try to arrange to have it placed somewhere where you can
grab it, otherwise, I can just send you a CD. I could trim the package a fair bit
if necessary - I've got a fair number of reference books and other material scanned
that you couldn't legitimately post on a web site anyway.

Sure, I can include some - I have them on file already.
I'll contact you via email when I have something in place that you can

Someone who is truly dedicated to the cause of computing, who understands that
computing technology took the wrong turn about 20 years ago, and who is
dedicated to fixing it and setting it back on track.
That's why I'm building a new VAX, a real bona fide VAX product just like DEC,
NOT an emulator.
When the Republic of Mars declares independence and holds its first presidential
election, I'll definitely run with a platform of immigration and customs laws
that would require migrants from Earth to leave their pee seas behind and allow
only Classic Computers to be used in the Republic of Mars. Supplying the entire
Republic of Mars with enough VAX processors will be no small task, and the
limited stockpiled of old DEC gear will certainly be insufficient. We need new
production.
We need new real Classic Computers in full production. Emulators are not the
answer: what are you going to run your emulator on if non-Classic computers are
banned?

By development software I assume you mean the tools for working with Verilog
(simulation and synthesis), right? I'm using the open source Icarus Verilog and
it can run on anything, though since it's written in Anshit C I'm forced to use
gcc rather than native cc. I guess if necessary it can be run through
unprotoize and thus made truly portable.
Not sure what you mean by bootstrap software, if you mean things like VMB,
that's written in VAX macrocode and runs on the VAX, so I don't see where the
problem is.
I'll also have a real console FEP to implement the functions of Chapter 10 of
the VAX spec (lacking the real STD 032 I use the chapter and section numbering
>from VARM 2nd ed.), for which I will use some 8 or 16-bit microprocessor of the
appropriate time period. Fortunately there are 8/16-bit microprocessors that
existed at the time of VAX-11/7xx and are still made (Z80 and 8086 come to
mind).

The biggest problem you'll have is that hard disks will
fail on Mars. The atmosphere is not thick enough to float
the heads. You'll have to go back to paper tape and punch
cards.

Hi
Actually the worst I've seen is painters. They remove covers

that I've seen, they shorted a hot wire to ground so their fix

Nice surprise when I had to fix the water heater.
I don't think UL has anything to say about both lines being
switched by a common switch. I think they only talk about
an independent switch on neutral as being a problem.
UL is only interested in safety of the operator and not
the repairman. As long as it doesn't make the chassis hot
or start a fire, you can get UL on something that blows
up the electronics of a unit every time you turn it on.

No, you've got the timing slightly off. The end of the last ice age was around
13000 y BP (before present) and the big wrong turn in the history of this planet
was in the year 2024 BCE (i.e., about 4027 y BP) as explained in my very
important work on the subject:

Does anyone know the magic numbers to enter into Test 70 on a
uVax-2000 to properly format an RD-54 and an RD-52 that are not
recognized as being such due to being formatted by some other (PC)

Hi Folks,
I'm looking for information on the E&L Instruments Fox Trainer (MT-80Z) which is a Z80 based teaching tool.
I'd like to know what the power supply specifications are for the unit, is there documentation on the trainer and the embedded firmware (Eprom) on board ?
In looking through your archives I came across a post from John R. Keys Jr. (December 1, 2002) stating that he had a MultiTech Microprofessor MPF-1B which was part of the E&L Instrument Fox trainer. I don't know if John is still on this list and if he still has that information.
Any help would be appreciated.
Thanks Robo
