This is just a guess, but the Quantel line printer made by Teletype is probably a Teletype Model 40 from your description. I don't have any docs on it, but they should be readily available.

<I have to disagree with this, Allison, one of my points being: The value /

to a point that is true.
<The lowly Motorola 6809 at 2 Mhz outperforms a
<10Mhz 80286... by far. It also *smokes* the 6502. And other than Xenix 286
<(super-expensive), OS-9 is the most powerful OS available for these
<processors, and at a reasonable cost (When I bought my copy - $139.)...
the 6809 was pretty neat and close to PDP-11. It was however, slow!
Smoking a 6502 is not a contest, 16bit math and a few other things
the 6502 has trouble with impair it. Comparing it to a 286/10mhz,
sorry, no way. The 286 wasn't great but it was faster. Is OS-9 better
than DOS yes, Xenix, no. Is OS-9 better developed than most intel/ms OSs,
very likely. are there OSs for intel parts that show them better, yes.
The 6809 was still a mile behind the PDP-11 (either the T-11 chip or the
F11 cip pair and way behind the J11 chip).
Like you said marketing... who outside of us remembers OS-9 and the 6809?
Was the coco a better machine... no. It was good for it's time but the
system was still a grafted together set of pods and cables typical of many
of the trs-xx products.
People noticed the PCs and the like when they started to look competent,
complete and somewhat stable in operation. The contents of the box cpu
wise was more determined by the software development community than the
chip makers. IE: the guy in the lead for that time generally had the most
and best software widely available at low or no cost. That's why AppleIIs,
TRS-80s and PC are like house files for their respective times. No matter
how good or bad software to make them do useful work often drove them

My kit did not have a label with it when shipped either.
I have corresponded with others who tell me their's came
sans label too. One speculated that it is the early ones
which were sent out without labels. Don't know why.

First I am Maurice Hamm 30 years old and living in the Netherlands.
I have a privite collection of old Radio's, Tv's and computers.
The datapoint 1800, a dec pdp 11/23, a zx81, a commodore 64, a IBM 8086
What has happend.
I have reorgenized my collection room and got the craziesed idea to
start up my DATAPOINT 1800 computer. (1980 )
This was my first computer and had for several years lot of fun with it.
I am industrious seeking for somebody that knows something about this
machine or has some information or docs
I got the machine in 1988 and has worked for several years whith it.
But now after several years I start up the machine and it did not start
up, the screen keeps black !!
There is power in the machine, the disks spins and the picture tube is
There is also no response of the keyboard.
I think the ROM is emty.
There is no self test.
I know for certain that it was in a working state the last time I had
used the machine +/- 7 years ago.
I opened the case to look for bad fuses or contacts but every thing
What has gone wrong?
I know its a long time and a very, very old machine But I just like to
see this machine working again.
The comp. works under DOS.G
I have several programes and documentation and a wheel printer attached
to this comp..
Please help me.
Greatings, and a Happy new Year,
You have GOT to see this page! It will sure as heck lighten up your day,
especially if you're looking at the ice collect on the phone and power
lines like I am.....
Check the "dancing baby" page out as well, very funny.
And now back to our regularly scheduled mailing list....
I've got a Qantel model 10 system sitting around the house.
My wife used to (I guess she still does occasionally) program
Qantel was a hardware manufacturer out of Hayward Ca.
They went out of business (sort of) around 1987/88. I say
'sort of' because I think Mohawk Data Systems bought
the support rights. I also think that someone may have
attempted recently to relaunch parts of their product line.
Anyway this system isdefinitely 10 years old. I'd like to see
what hardware documentation might be floating around out
there for this.
In particular I have a real nice High-speed line printer that
I would like to get service and interface info on. It was
manufacture by Teletype but I haven't been able to find a
model number on it and I didn't want to disassemble it
It is currently still working fine, but I'd like to connect it to
some other equipment. From the little I've examine it, it
appears that it might be a current loop interface (the era
is right for this also).
Anyone familiar with this printer?

Now I'm 6 for 6. All six work, all pass interchangeability. For those
3 Seimens model FDD 200-8P
1 Seimens model FDD 120-8
1 Seimens model FDD 100-8
1 Shugart model 801 (missing one cap)
Now to go through and jiggle all of the boards in the C3-D, power it up
and see if she boots. Wish me luck.
Can anyone point me to a good utility for testing memory that DOS 6.22
(HIMEM) occaisionally reports as suspect? I'm looking for something
other than yanking the SIMM's out, and testing them (it's a govt owned
'puter, and the repair person 'll take forever if I don't provide some
serious guidance as to the cause of the problem).. Yeah, I've thought
of opening it up, and cleaning the contacts on the SIMMS etc, but, as
a Contractor Employee, I don't want to risk getting my company getting
blamed for anything..
I have an IBM XT with monitor & keyboard. Anyone interested?
