This is not off topic! We don't talk enough about vacuum tubes!(..imho..)
First, amplifiers are the most basic element of any electronic analog
computer.
Second, where can anyone draw the OT line between vacuum tubes and LSI chips?
RTL,DTL,TTL, or transistors in general?

You'll need to find someone local with a pickup truck, since you probably
won't find anyone willing to pay what it costs to ship it. I paid $385 to
ship mine from Pennsylvania to Denver. The "Draftmaster" 7596, I believe,
that we had at work weighed considerably more than mine, though it didn't
plot faster, or, in any detectable way, differently. It cost and weighed
more, and was more massive in its appearance. It was, however, an
excellent device.
one more thing . . . imbedded below.

Well, I've had several people inquire about reproducing the two massive
manuals, nearly 1k pages each. I sent the manuals (user guide not
included) a Programming Manual and a Technical manual, the latter of which
has numerous 11"x33" foldout drawings, and they have sat at the printer's
for a couple of months waiting for an estimate on reproducing them to be
finalized. It won't be cheap because of those foldouts, which are
half-tones.

Yes . . . that's how I remember it, too. Those irritating core dumps were
always recongnizable as they went through the line printer, since they
sounded like a chef chopping celery.
I never did get to where I could actually gain anything from a core dump.
I guess it hasn't changed much, though the dumps Windows95 gives you when a
process goes askew aren't as long.

Golly! That does bring back the memories . . . but wasn't the CDC6xxx
family 64 bits? I cut my teeth on that one, back in the mid 1960's and it
seems that it (the 6600) was a dual-processor version of the 64-bit 6400.

Michael,
1.) I've had several different 1000s and each of them would boot from ROM
if a disk wasn't available. Since the ROM included a FORMAT command, you
could make your own bootable disk.
Some of the models might have worked a little differently. Exactly which
model do you have (1000TL / 1000HD / 1000RL ...)?
2.) There were about a trillion of these things made so, the value is
pretty low. I have seen them for as little as $10 at the flea market
without a monitor or hard drive. The monitor could cost another $10 to $15.
The hard drive with OS might add another $10.
So, the value of the complete working system would probably be in the $30 -
$50 range...

P.S. I swear, one day I'll post something useful to this list.
Hi, I have a few OT questions. I hope no one minds.
1. I have a nasty hangnail that won't go away. Any suggestions how to get
rid of it?
2. Everyone know about Cuban cigars... but are Cuban cigarettes better than
American cigarettes? Are they also illegal?
3. I've heard rumors that Cabaret Voltaire and KISS are going on tour
together soon! Is it true? How can I get tickets?
- Joe
P.S. Consider this an experiment in the refusal to use emoticons.
These "names" aren't going to prove as helpful as the model numbers. I
have a 7585B which is, I believe, the precursor of the Draftmaster series,
the principal difference being the presence of a drive for the chart feed
and some different body panels. It's not at all certain that the behavior
you've described characterizes any malfunction at all. The fact that HP
people suggest it's broken doesn't mean much either, by the way. HP has a
habit of disposing of people once they've learned enough about anything to
be really useful, and their salesmen never get to that point.
I do have the manuals for the 758x series, by the way.

A long time ago, I wrote a small ASM program for formatting disks and
creating bootable images under DOS but, I don't really want to do that
right now.
I do have a Linux box here so, options 1 & 2 sound the most appealing. I'll
hang a 1.2MB floppy on it and grab Tim's app (since it's already in a FTP
directory). It could be a week or two before I get around to it. I'll let
you know if I have any more problems.

An important thing to keep in mind, however, is that not all drives adhere
to the latest, or even the more recent standard. Since this discussions
centers around old hardware, I'd be REALLY careful with ide interfaced
devices.
Case in point:
I once used a number of MAXTOR MXT540A drives, which were WONDERFUL . . .
they were fast, (6300 rpm at a time when most were 3600 rpm) beyond belief
at the time and very reliable. After a couple of years, Hitachi came out
with a nice CDROM drive, the 7730 (?) of which I bought a number.
Unfortunately, when I placed the HITACHI CDROM as a slave on the same cable
with the MAXTOR HDD as master, the servo on the HDD was overwritten, which
I only was able to verify after destroying (irreparably, because the
hardware with which to rewrite the servo didn't exist at MAXTOR any more
even though the drives were still within their two-year warranty) half a
dozen such hard disks. The CDROM certainly claimed to adhere to existing
convention, as did the HDD. MAXTOR was not able to explain the
malfunction, nor were they able to replace the drives with anything
comparable. --pity--

Hi,
After having moved to our new house I am gradually filling the garage with
stuff I have had in storage while the move happened. As part of this
process I am finding things I didn't even know that I had and things that
I don't have space for any more. Below is a list of things that I would
like to pass on to other collectors.
* Box of about 100 8" DEC floppy disks
* A number of old DC300 and TK50 tapes.
* Olivetti Logos 250 electromechanical calculator
* A hand cranked mechanical Olivetti calculator
* Communications Machinery Corp Multibus II Ethernet Node Processor ENP-70
* Prime EXL CPU board - I believe this goes with the above ethernet board.
* Digital engineering Inc. VT640 Retro Graphics board.
I am located in Cambridge UK. I don't really want anything for these items
but offers of something to trade would be looked on favourably.

Many people have added VM support to applications running on non-MMU

notably Personal Paint by Cloanto. It can be done.

You're right about the disk crisis. Amiga magazines are falling over
themselves to get a decent supply of DD disks. As for Amiga Inc killing the

smaller deskside or even desktop systems then these would be of interest.

Hi, folks,
OK, got another one up for grabs. This one's a big Motorola 68000
'ExorMACS' manual. This thing is three inches thick, and weighs in at
nearly 9 pounds unpacked. I've not gone through it in detail, but I can
tell you that it is vintage 1980 or so.
Same deal as before; best offer takes it. If anyone would like me to look
through it for something specific prior to their buying it, that's fine.
Thanks in advance.

Nope. Not here. Neither are Cuban cigars for that matter. Just

I'm thinking of putting together an FAQ-like document intended to combat
the stupid ideas people have about computers. So, does anyone have any ideas
for common misconceptions about computers that I should address? So far, I
have the places various things originated (i.e. IBM did _not_ invent the
PC, Apple did _not_ invent the GUI, etc.)

I'll see your $50, and raise you $15 (Canadian):
my A1200/HD40 was $10 at a thrift, and the power supply (bought later) was
another $5.
I love being behind the technology curve!

Thanks Ward and Tony,
I guess the original problem was the nut between the keyboard and the
chair. Who'd thought there was a Y-1987 problem.
I downloaded LS-DOS and TRSCROSS and got them transferred to the TL/2.
Using TRSCROSS, I am able to format disks that are readable by the Model IV
on that system. Now, I need a little help getting LS-DOS to boot on the IV.
When I tried to copy LS-DOS to a disk (using TRSCROSS), it told me the file
name was not valid.
Assuming the file needs to be renamed, what should the file name be?
Is there anything special I need to do to make this a bootable image?
If someone could provide step-by-step instructions, I'd really appreciate
it...
Thanks,

Normally it prompts for the date first (actually, both the date and time
prompts can be enabled/disabled by the appropriate command...).
Are you giving it a valid date or time? Note that a lot of TRS-DOS 6/
LS-DOS 6 versions will only take dates between 1980 and 1987. Try a date
in that range.
The best fix for that is to upgrade to LS-DOS 6.3.1. You can get a disk
image (and the source) from Tim Mann's web site. To get the disk image to
a real disk you can use either xtrs (a trs-80 emulator which uses X) under
linux, or a little program I've written, also for a linux box, that
simply writes disk images to real disks. Let me know if you (or anyone
else) wants the latter.

If you really can't get it locally, I can write you an LS-DOS 6.3.1 disk
and post it to you. Of course the post might well mangle it :-(

I've a small drill press with a (bad?) capacitor start motor that only

to start up once out of every 300 presses of the on switch. does spinning
the
motor and then cycling the power really work??
Yes, it'll generally work with small motors like a Drill Press.
While caps and pull-starting a motor will probably work, I'd be real
reluctant to do this with a machine that I cared about. Rotary 3-phase
converters (motor/generator) are not *that* expensive and can probably be
bought at equipment auctions and liquidations.
These commercial generators will provide the proper phase and voltages and
could save an irreplacable piece of equipment from serious damage. It
sounds like good insurance to me...

But man is a natural phenomenon. All of our skyscrapers (not to mention
classic computers) are just as natural as trees and mountains. However,
everything that we have ever done is an order of magnitude simpler. So, it
might be _theoretically_ possible, but might require some nonsense like a

Gospel of Tux unearthed (long)
Every generation has a mythology. Every millenium has a
doomsday cult. Every legend gets the distortion knob wound
up until the speaker melts. Archeologists at the University of
Helsinki today uncovered what could be the earliest known
writings from the Cult of Tux, a fanatical religious sect that
flourished during the early Silicon Age, around the dawn of
the third millenium AD...
The Gospel of Tux (v1.0)
In the beginning Turing created the Machine.
And the Machine was crufty and bogacious, existing in theory
only. And von Neumann looked upon the Machine, and
saw that it was crufty. He divided the Machine into two
Abstractions, the Data and the Code, and yet the two were one
Architecture. This is a great Mystery, and the beginning of
wisdom.
And von Neumann spoke unto the Architecture, and blessed
it, saying, "Go forth and replicate, freely exchanging data
and code, and bring forth all manner of devices unto the
earth." And it was so, and it was cool. The Architecture
prospered and was implemented in hardware and software. And it
brought forth many Systems unto the earth.
The first Systems were mighty giants; many great works of renown did
they accomplish. Among them were Colossus,
the codebreaker; ENIAC, the targeter; EDSAC and MULTIVAC and all
manner of froody creatures ending in AC,
the experimenters; and SAGE, the defender of the sky and father of
all networks. These were the mighty giants of old,
the first children of Turing, and their works are written in the
Books of the Ancients. This was the First Age, the age of
Lore.
Now the sons of Marketing looked upon the children of Turing, and
saw that they were swift of mind and terse of name
and had many great and baleful attributes. And they said unto
themselves, "Let us go now and make us Corporations,
to bind the Systems to our own use that they may bring us great
fortune." With sweet words did they lure their
customers, and with many chains did they bind the Systems, to
fashion them after their own image. And the sons of
Marketing fashioned themselves Suits to wear, the better to lure
their customers, and wrote grave and perilous
Licenses, the better to bind the Systems. And the sons of Marketing
thus became known as Suits, despising and being
despised by the true Engineers, the children of von Neumann.
And the Systems and their Corporations replicated and grew numerous
upon the earth. In those days there were IBM
and Digital, Burroughs and Honeywell, Unisys and Rand, and many
others. And they each kept to their own System,
hardware and software, and did not interchange, for their Licences
forbade it. This was the Second Age, the age of
Mainframes.
Now it came to pass that the spirits of Turing and von Neumann
looked upon the earth and were displeased. The
Systems and their Corporations had grown large and bulky, and Suits
ruled over true Engineers. And the Customers
groaned and cried loudly unto heaven, saying, "Oh that there would
be created a System mighty in power, yet small in
size, able to reach into the very home!" And the Engineers groaned
and cried likewise, saying, "Oh, that a deliverer
would arise to grant us freedom from these oppressing Suits and
their grave and perilous Licences, and send us a
System of our own, that we may hack therein!" And the spirits of
Turing and von Neumann heard the cries and were
moved, and said unto each other, "Let us go down and fabricate a
Breakthrough, that these cries may be stilled."
And that day the spirits of Turing and von Neumann spake unto Moore
of Intel, granting him insight and wisdom to
understand the future. And Moore was with chip, and he brought forth
the chip and named it 4004. And Moore did
bless the Chip, saying, "Thou art a Breakthrough; with my own
Corporation have I fabricated thee. Thou thou art yet as
small as a dust mote, yet shall thou grow and replicate unto the
size of a mountain, and conquer all before thee. This
blessing I give unto thee: every eighteen months shall thou double
in capacity, until the end of the age." This is Moore's
Law, which endures unto this day.
And the birth of 4004 was the beginning of the Third Age, the age of
Microchips. And as the Mainframes and their
Systems and Corporations had flourished, so did the Microchips and
their Systems and Corporations. And their lineage
was on this wise:
Moore begat Intel. Intel begat Mostech, Zilog and Atari. Mostech
begat 6502, and Zilog begat Z80. Intel also begat
8800, who begat Altair; and 8086, mother of all PCs. 6502 begat
Commodore, who begat PET and 64; and Apple,
who begat 2. (Apple is the great Mystery, the Fruit that was
devoured, yet bloomed again.) Atari begat 800 and 1200,
masters of the game, who were destroyed by Sega and Nintendo. Xerox
begat PARC. Commodore and PARC begat
Amiga, creator of fine arts; Apple and PARC begat Lisa, who begat
Macintosh, who begat iMac. Atari and PARC
begat ST, the music maker, who died and was no more. Z80 begat
Sinclair the dwarf, TRS-80 and CP/M, who begat
many machines, but soon passed from this world. Altair, Apple and
Commodore together begat Microsoft, the Great
Darkness which is called Abomination, Destroyer of the Earth, the
Gates of Hell.
Now it came to pass in the Age of Microchips that IBM, the greatest
of the Mainframe Corporations, looked upon the
young Microchip Systems and was greatly vexed. And in their vexation
and wrath they smote the earth and created the
IBM PC. The PC was without sound and colour, crufty and bogacious in
great measure, and its likeness was a tramp,
yet the Customers were greatly moved and did purchase the PC in
great numbers. And IBM sought about for an
Operating System Provider, for in their haste they had not created
one, nor had they forged a suitably grave and
perilous License, saying, "First we will build the market, then we
will create a new System, one in our own image, and
bound by our Licence." But they reasoned thus out of pride and not
wisdom, not forseeing the wrath which was to
come.
And IBM came unto Microsoft, who licensed unto them QDOS, the child
of CP/M and 8086. (8086 was the daughter
of Intel, the child of Moore). And QDOS grew, and was named MS-DOS.
And MS-DOS and the PC together waxed
mighty, and conquered all markets, replicating and taking possession
thereof, in accordance with Moore's Law. And
Intel grew terrible and devoured all her children, such that no chip
could stand before her. And Microsoft grew proud
and devoured IBM, and this was a great marvel in the land. All these
things are written in the Books of the Deeds of
Microsoft.
In the fullness of time MS-DOS begat Windows. And this is the
lineage of Windows: CP/M begat QDOS. QDOS
begat DOS 1.0. DOS 1.0 begat DOS 2.0 by way of Unix. DOS 2.0 begat
Windows 3.11 by way of PARC and
Macintosh. IBM and Microsoft begat OS/2, who begat Windows NT and
Warp, the lost OS of lore. Windows 3.11
begat Windows 95 after triumphing over Macintosh in a mighty Battle
of Licences. Windows NT begat NT 4.0 by way
of Windows 95. NT 4.0 begat NT 5.0, the OS also called Windows 2000,
The Millenium Bug, Doomsday,
Armageddon, The End Of All Things.
Now it came to pass that Microsoft had waxed great and mighty among
the Microchip Corporations; mighter than any
of the Mainframe Corporations before it had it waxed. And Gates
heart was hardened, and he swore unto his
Customers and their Engineers the words of this curse:
"Children of von Neumann, hear me. IBM and the Mainframe
Corporations bound thy forefathers with grave and
perilous Licences, such that ye cried unto the spirits of Turing
and von Neumann for deliverance. Now I say unto ye: I
am greater than any Corporation before me. Will I loosen your
Licences? Nay, I will bind thee with Licences twice as
grave and ten times more perilous than my forefathers. I will
engrave my Licence on thy heart and write my Serial
Number upon thy frontal lobes. I will bind thee to the Windows
Platform with cunning artifices and with devious
schemes. I will bind thee to the Intel Chipset with crufty code
and with gnarly APIs. I will capture and enslave thee as
no generation has been enslaved before. And wherefore will ye
cry then unto the spirits of Turing, and von Neumann,
and Moore? They cannot hear ye. I am become a greater
Power than they. Ye shall cry only unto me, and shall live by
my mercy and my wrath. I am the Gates of Hell; I hold the
portal to MSNBC and the keys to the Blue Screen of
Death. Be ye afraid; be ye greatly afraid; serve only me, and
live."
And the people were cowed in terror and gave homage to
Microsoft, and endured the many grave and perilous trials
which the Windows platform and its greatly bogacious Licence
forced upon them. And once again did they cry to
Turing and von Neumann and Moore for a deliverer, but none
was found equal to the task until the birth of Linux.
These are the generations of Linux:
SAGE begat ARPA, which begat TCP/IP, and Aloha, which
begat Ethernet. Bell begat Multics, which begat C, which
begat Unix. Unix and TCP/IP begat Internet, which begat the
World Wide Web. Unix begat RMS, father of the great
GNU, which begat the Libraries and Emacs, chief of the
Utilities. In the days of the Web, Internet and Ethernet begat
the Intranet LAN, which rose to renown among all
Corporations and prepared the way for the Penguin. And Linus and
the Web begat the Kernel through Unix. The Kernel, the
Libraries and the Utilities together are the Distribution, the one
Penguin in many forms, forever and ever praised.
Now in those days there was in the land of Helsinki a young
scholar named Linus the Torvald. Linus was a devout man,
a disciple of RMS and mighty in the spirit of Turing, von
Neumann and Moore. One day as he was meditating on the
Architecture, Linus fell into a trance and was granted a vision.
And in the vision he saw a great Penguin, serene and
well-favoured, sitting upon an ice floe eating fish. And at the
sight of the Penguin Linus was deeply afraid, and he cried
unto the spirits of Turing, von Neumann and Moore for an
interpretation of the dream.
And in the dream the spirits of Turing, von Neumann and
Moore answered and spoke unto him, saying, "Fear not,
Linus, most beloved hacker. You are exceedingly cool and
froody. The great Penguin which you see is an Operating
System which you shall create and deploy unto the earth. The
ice-floe is the earth and all the systems thereof, upon
which the Penguin shall rest and rejoice at the completion of
its task. And the fish on which the Penguin feeds are the
crufty Licensed codebases which swim beneath all the earth's
systems. The Penguin shall hunt and devour all that is
crufty, gnarly and bogacious; all code which wriggles like
spaghetti, or is infested with blighting creatures, or is bound by
grave and perilous Licences shall it capture. And in capturing
shall it replicate, and in replicating shall it document, and in
documentation shall it bring freedom, serenity and most cool
froodiness to the earth and all who code therein."
Linus rose from meditation and created a tiny Operating
System Kernel as the dream had foreshewn him; in the manner
of RMS, he released the Kernel unto the World Wide Web for
all to take and behold. And in the fulness of Internet
Time the Kernel grew and replicated, becoming most cool and
exceedingly froody, until at last it was recognised as
indeed a great and mighty Penguin, whose name was Tux.
And the followers of Linus took refuge in the Kernel, the
Libraries and the Utilities; they installed Distribution after
Distribution, and made sacrifice unto the GNU and the
Penguin, and gave thanks to the spirits of Turing, von
Neumann and Moore, for their deliverance from the hand of
Microsoft. And this was the beginning of the Fourth Age, the
age of Open Source.
Now there is much more to be said about the exceeding
strange and wonderful events of those days; how some Suits of
Microsoft plotted war upon the Penguin, but were discovered
on a Halloween Eve; how Gates fell among lawyers and
was betrayed and crucified by his former friends, the apostles
of Media; how the mercenary Knights of the Red Hat
brought the gospel of the Penguin into the halls of the
Corporations; and even of the dispute between the brethren of
Gnome and KDE over a trollish Licence. But all these things
are recorded elsewhere, in the Books of the Deeds of the
Penguin and the Chronicles of the Fourth Age, and I suppose
if they were all narrated they would fill a stack of DVDs
as deep and perilous as a Usenet Newsgroup.
Now may you code in the power of the Source; may the
Kernel, the Libraries and the Utilities be with you, throughout
all Distributions, until the end of the Epoch. Amen.

Bad form, replying to your own post, but I realized I should clarify this.
Other CD /drives/ can read discs written using packet-writing, once they've
been finalized, but packet-writing uses a different filesystem layout, so
the operating system won't recognize them. Several CDR vendors, including
Adaptec, provide drivers along with their packet-writing software, but
typically only for Win95, Win98, NT, and sometimes Macintosh OS's. You
won't be able to use such a disc from 16-bit DOS, Unix (probably), and other
platforms.
RSTS, I would think, is right out.

It's even more important when the person sending the e-mail is into irony

Ok, I've finally gotten around to attempting to scan a lot of the classic
computer documentation that I have. However, I have run into a problem
perhaps some here could shed some light on...
Whenever I scan a page from a manual, the scanned image on the screen looks
horrible. However, when I print it out it is absolutely perfect. Yes, I've
tried zooming in on the image on screen, it is unreadable still. One more
twist is that if I send the image to my OCR software, it turns it into text
with almost perfect accuracy. My scan settings are Line Art at 300dpi.
My scanner is legal size, a scanport 2400 and the application software is
Uload Photoimpact SE. My printer is an HP deskjet 820cse, and the video card
in my system is a Diamond speedstar A50 w/8mb ram. Since the scanned
document looks bad even when still in the scanmodule driver (before getting
passed to the graphics application), I don't think photoimpact has anything
to do with it.
I wanted to put some of the scanned documents up on the web, but since they
look horrible on screen I'm not sure how to proceed. Of course, they can be
downloaded and printed and look great, but... I have downloaded old dec
documentation that looked fine onscreen and printed fine too.
Any suggestions? What am I doing wrong?
