Yeesh, if you run into any, I'll trade you for them! I have several
friends looking for them.
I know of only two collectors besides myself who have 5100's. In
contrast, there are about 15 Altairs represented on this mailing list.
I do know of an Apple I that's for sale... anybody got $10,000 burning a
hole in their pocket? Yeesh.

Maybe we can help someone sell an old system in the future. I'm just now
fooling around with an internet auction. We hope to do another in the future.

how much you asking? I'll pick up the postage and little something for your

Dug up an HP 9831A...single-line, dot matrix display, full keyboard desktop
unit (abt the size of a typewriter). Looks fairly old.
Seems to be a full computer (not a programmable calculator, which they also
made a lot of), as it wakes up in a BASIC mode. I get a lot of error
messages --probably due to improper commands. It will accept and run a
simple program.
Anyone want it?

Lets try and help this guy out, he is trying to hook the young!
I got a call yesterday from this guy who was looking for a disk drive for an
Amiga 500, he is trying to set it up for his young niece. As luck would have
it, a disk drive was the only piece of Amiga hardware that I have, so I went
down there today to set it up for him. Unfortunately, it seems that the
problem is not the disk drive but the floppy controller (i think). Not being
fortunate enough to have owned an Amiga myself, I am at a loss. Here is the
problem in brief:
The machine will display the little picture asking for the disk...
Put the disk in, and the drive is polled, but doesn't read it, so it ask
again for the disk...
I tried my drive in the system, with the same result (hence thinking it
might be the controller)...
I'm not exactly sure if it is the right disk he has, he ordered it from
Toronto at a cost of $26.00 (can), it says Amiga workbench, however I am not
sure if that is really what is on it...
I would appreciate any help or suggestions from anybody who might have
come across this situation before.
Remember: This guy is setting this up for his young niece, who calls every
day asking if it is ready yet. I think its great to get the young into
classic computing (my own nieces just call my machines door stops, and call
me a geek for having them ;)

At a swap meet or garage sale most people expect you to haggle. That is part
of the game. You can tell pretty quick if they're not into it becuse they say
no to your offer. Most of the people I buy stuff from are just trying to get
rid of it. They're more than happy to bargain. Especially if you buy all the
boxes of "computer junk" they have.
On the other hand there's a lady who hauls out an old Amiga 500 without power
supply or mouse every week and is "Firm at $100". Someday she'll figure it
out. (usually $5-$10 at Goodwill)
I recall a stubborn seller a few years back. I was searching for a collectible
Coke machine. I called a guy that had one for $1000. I mentioned making an
offer once I had seen it and he told me he was "firm" on $1000 and seemed
insulted. Well, before I could get there to check it out, a fellow collector
drove down there within an hour and hauled it away for $200! Funny thing is
that at the time I was ready to fork out at least $600 for it! You can never
tell what people are thinking.
No transputers, but I know where you can get a 1450XLD from an ex-Atari
employee, although he is only willing to sell it if he gets "the right
price", whatever that is.

Rich,
I have found that getting hardware is relatively easy. I probably have
enough pieces to put together a half-dozen Q-Bus 11's, although I consider
most of the pieces "spares". Software, however, is another matter.
Original distribution disks with accompanying documentation has been hard
to come by. If you have any knowledge of DEC OSs, grab all you can get.
For instance, I have been looking for an original distribution (disks,
docs) for RT-11 Version 5.2 or later. If you run across a spare one of
these, I would be happy to help you dispose of it! :)

OK, here is the complete listing from the CCC of the machines made by
Atari. Please consult your favorite references and confirm/deny or
complete the missing data.
I would like a month/year for the first customer shipment or the first
public working demonstration of the machines. Please provide references
where possible, if they are on-line then so much the better.
I am also planning to extend the information per machine to include data
about processor used, word-size, memory configurations etc. so feel free
to add that data also.
I have set the reply to address to my personal Email so as not to
clutter the mail list. You can always go to the CCC to recover the
updated data. If there are enopugh requests I can post an updated
preview table here before the CCC gets updated.
I would also be interested in a potted history of the manufacturer, date
started where located and significant events in its history. I know most
of this is probably available on the NET for Atari, but not for some of
the more obscure companies.
CCC list for Atari
I think I am correct in saying that all Atari machines were designed in
the USA.
