I have a Dragon 32,. working last time I checked. If you're coming
here this week, you can borrow it for comparison testing if you like.

Just a quick note to say I am still in the process of getting rid of my
excess "treasures" :). They are listed on VCM at
http://marketplace.vintage.org/. I'll be putting stuff on for the rest
of this week at least, so it might be useful to check the site
occassionally ... or frequently :). The stuff I am putting up is mostly
for sale, and not for auction.

Hi
You see, knowledge already lost. Yes, a magnetron has a vacuum in it.
It has a filament and a plate ( with cavities in it ). While the
principles of these things can be found in books, much of the
mechanical and physical methods used to create these things is lost.
Partly because of the fact that manufactures don't tell all and
partly because no one is dealing with these kinds of things.
While it is claimed that the information is in books, there
are some feel things that rarely seem to make it into these
books. Can anyone tell me what controls the gain of a vacuum
tube ( other than someone that actually worked with these )?
Can anyone tell me how the grids must be placed for an electrometer
preamp tube and why? While we don't need these kinds of things today,
the knowledge of what makes these things work is still quite
valuable. This understanding can keep us from making mistakes
with other related problems. I can't say that these specific
things that I've mentioned will be the most important things
to remember but these are the types of tidbits that make
the difference when looking into new problem areas of the
future.
Those that understand these things will always be in demand.
Those that think they can ignore these kinds of things will
wonder why things are beyond understanding. This goes
for the entire range of things. You can't understand how
to think about things without actually thinking about things.

I'm sorry to have to bother the whole list with this. I already wrote
to cctalk-owner and got no response whatever as far as I can tell; I
figured I'd let myself try the list, once, in the hope someone is
watching there but not at the -owner address.
It seems my subscription has been "disabled due to excessive bounces".
The mail saying so includes a token that I can supposedly send back to
reenable things, but it doesn't work, probably because the list
software (a) waited ten days after disabling before telling me anything
and (b) didn't generate a newly-valid token after waiting.
The last rejection (not bounce, no matter what the message thinks - I
don't accept-and-bounce except under very unusual circumstances) was
July 3rd (not the July 6th claimed by the message, unless later
attempts came through a different host), and I got no notification
until July 13th. I replied immediately and got told the token was
invalid (with a note that they're good for only three days). I sent
the whole mess off to cctalk-owner.
Just now, a week later, I got a second notice of disablement. It
included _the very same token_, despite it now being a week older. (It
still doesn't work.)
Today's notice of disablement and the response to my reenablement
attempt are quoted below, after my signature. Does anyone know what's
wrong here and whom I need to nudge to get it fixed? As I said, I've
already tried cctalk-owner. (Obviously, I won't see on-list replies
here; direct, or at least copy to me, would be needed for me to get
it.) I can dig up copies of last week's notice and response too, if
desired.

My new classic computer room is quickly filling up
and I need to clear out some space. In my quest to
find a working Dec VT52, I have acquired several dead
or semi-dead ones that I don't want to spend the time
to troubleshoot right now. I also have a VT61 that
powers up to a flashing "block style" cursor. I have
not attempted to connect it to the PDP-11/34 because
I do not have my 11/34 set up for a 20mA connection.
If anyone would like a VT52 or the VT61, let me know.
I have a minimal amount of money in these ($30 to
$50 each) and would be willing to sell them for that
price. I've been watching eBay for 6 months and have
only seen one of these types of terminals on there.
For those of you who aren't familiar with them, they
were commonly used on DEC systems (PDP-8 and PDP-11)
back in the mid-1970s and later.
I have two or three VT52s and the VT61 that I'm wanting
to get rid of. The VT61 seems to be quite uncommon.
I can't find much about it on Google. It had more
features than the VT52 and I think did "full screen"
processing, but I'm not sure.

Can't resist. This is not really in response to your
question, but at least on-topic.
In the late '80s, I shared an office with 3 other grad
students. One had a Mac SE/30 and was ahead of the rest of us in
learning the internet. He got the serial line connection to the
building Unix box run into our office, discovered how to ftp files
>from internet sites, D/L over serial to the macs, decompress, etc.
One night around midnight (when the rest of us were asleep),
he discovered a site with a bunch of sound clips from movies, and
software to substitute the clips for system beep, startup chime, etc.
He went to work, and got his box all set up the way he wanted.
Next morning, I came in long before he was up, and fired up
his machine to do something on it. Instead of <Beeeeep!> it said "My
GOD! It's full of *STARS*! <opening strains of Also Sprach
Zarathustra>".
Oh, verrry nice. I explored the new directory, discovering
eventually clips from "Alien" among quite a few others. I *also*
discovered the graphical sound-clip editor that came with the package.
Hmmm. I set to work.
An hour or so later, the owner of the machine walked in, a
bit bleary-eyed but looking smugger than anyone I have ever seen
before or since. "Hey, guys", he chirped, "I found some new software.
Wait'll you see!" Sitting down at his desk, he gave us all another
smug look, flipped the switch and leaned back in his chair as the
disk spun up. "What?" we said, our best innocent looks plastered
across our faces, "a new startup screen or something?" "You'll
see..." came the response.
The computer finally piped up, "My GOD! It's full of <click>
*..SH1T..* <click> <opening strains of Also Sprach Zarathustra>". It
turns out Sigourney Weaver's voice (as in Alien), if
frequency-shifted down about half an octave, is almost a dead ringer
for Keir Dullea's (as in 2001).
Mr. Smug's head snapped around in the fastest double-take
I've ever seen. "WHAT!" Then realization set in.. "You guys...."
He cleaned up the <click>s and kept the startup sound for
months, though.

This appeared on the dragonuser site - looks like a very interesting
machine. He's based in Wiltshire but does travel around a bit if anyones
able to help with basic faultfinding .
By the way Jules - Dragon diagrams are available from the Dragonuser group.

P.S. Had a good dig around in the front part of the loft but no Nascom yet ,
although I did find my two Nascom Imp Printers - chassis only , bought a
long time after Nascom ceased to exist.

Subject: [dragonuser] Help with Dragon *Beta* Main Board
Hi all,
I have come into possession of a Dragon Data Beta (aka. The ?2500
business machine) prototype main board. The sad news is that
appears to be dead. Is there anyone out there who could possibly
help in getting this beastie back into life?? (If it ever worked)
Serious reverse engineering and electronic skills required! I've
had a poke about with an oscilloscope and it is clocking OK and
there is life on the data buses.
I have uploaded a few pics into the photos section.
For those interested it appears to have the following features:
? 256 K RAM
? Twin 6809E's clocked at 1.8Mhz
? Onboard Floppy controller (3.5" Single sided drives)
? Onboard RS232
? Optical interface
? External Keyboard (no keyboard L )
? Unkown DIN connector - Mouse? Light Pen??
? No built in Drag 64 mode! Only an OS-9 boot ROM (ROM dumps
available).
Simon Hardy is also holding (most of) a Dragon Data Alpha (aka
Professional) prototype for me. More info on this in the coming
months when we can actually get a power supply attached.

Hello, all:
I was at VCFe yesterday and I have to say that the speakers and
demonstrations were great. Sellam did a fantastic job and where the event
was located at the Sun facilities worked out perfectly. One demo that I
missed was the ARPANET dial-up simulation which wasn't there when I left at
3:30.
Anyway, this demo brings-up an interesting question. What kind of dial-up
systems existed in the 70's before consumer-oriented services like
CompuServe? I remember the DowJones and CompuServe sign-up packs at
RadioShack in maybe 1979 (I joined CIS in 1988. I even remember my ID:
70153,3367). I also remember in high school (around 1983) using a DECwriter
to dial into the timesharing computer (at 300 baud; I don't know the host
system) at one of the local universities.
Just curious. Thanks.
