Who else would know the answer but Atari fans. Why I'm posting here.

Yeeeeeears ago I saw what I recall as a bog standard vanilla pc branded ATARI. I had thought this was the PC-1 (before I actually learned what the PC-1 looked like). Does anyone know what I'm talking about? This was as close to the original 5150 as you can imagine. Was this a hoax, or some very rare Atari item?

They did make them, yes. The case looked like a Mega ST with a 5.25" disk drive in it.

"In 1987 Atari introduced a line of IBM compatible computer systems starting with its Atari PC-1 which was an all-in-one IBM XT compatible computer with built in disk drive, built in serial, parallel, keyboard, mouse and video ports (video could be configured for CGA, Hercules, EGA and other settings). An internal bus port on the motherboard allowed for an expansion card to use the Atari Mega ST Megafile hard disk system."

In Europe, Atari later sold generic beige-box PC clones under the "ABC" (Atari Business Computer) line.

ok no one knows what I'm referring to. Perhaps it was a prototype or something. I saw it on ebay.ca incidentally.

The other designs Atari had for PC compatibles were the PC2, PC3, PC4, and PC5 which resemble IBM 5170. No vertical 3.5" bay there. http://retropages.uw.hu/Atari.html look down a bunch and see a picture of the PC2 with black drives.
So prototype, system Atari purchased for internal use, or one of the specialties of Ebay: the generic clone enhanced with a badge taken off something else.

yeah any of the above, but I sure wish I had taken advantage of that auction. It just may have been something uber rare and uber cool.

On the other hand, it could just be someone who stuck an Atari badge on an IBM case :)

But why? Such a person would undoubtedly have to be in league w/Beelzebub.

Could it be this?

http://stelios-old-computers.webnode.gr/atari-pcs/atari-pc-4/

I'm not sure if this is a prototype but it's completely different to any other PC4 I've seen. The PC3, PC4 and PC5 all had the same chassis just modified slightly for the different internals.

I know this one. ATARI sold some relabled PCs from Mitac at least in Germany. This is one of them. I had one of these on my workplace desktop in 1990. Trying to get ATARI PCs today is like crazy, they are very expensive.

Interesting. Do you know where I could look up more information on this? That would certainly explain the different PC4 I linked in my last post. I was wondering why the motherboard in that particular machine had a slightly different layout and lacked any Atari branding like the example on my website does.

http://www.ataripc.net/pc4-286/motherboard/

Edit: I just found the Mitac PC they rebadged as a PC4.

In regards to Atari PC pricing, it's not so much the price but the rarity of these PC's. They show up on eBay from time to time, particularly in Germany, and prices are fairly reasonable. Just don't go thinking listings like the one below is normal. This seller has been listing this complete Atari PC3 for years without success because his asking price is WAY too high (it was higher!). I brought a complete PC3 from a seller in Germany over a year ago for less than half that price including shipping to Australia.

Interesting. Mitac also had a Paragon 386. Do you know if Atari did the same with that model and released a rebranded PC5 in Germany?

Found some pictures here of what appears to be the entire Paragon range: http://exhibition.ifdesign.de/entrydetails_en.html?beitrag_id=18006

It's interesting to piece this all together as it's starting to all make sense. The original PC4 I know was shown at Comdex '87 while this later Mitac rebadged as an Atari PC4 appears to be from '88, '89 when the Atari PCx series was coming to it's end. It seems to be a transition from the older PCx series to the newer ABC series with generic cases which were to follow in 1990. The fact this only appears to be a German thing isn't surprising as Germany was one of only a few markets where the Atari PC sold well.

I'm not surprised to hear. I've heard that said many times when I've mentioned I have Atari PC's.

They weren't big in the US in fact there were some models of Atari PCx series they didn't bring to the US market at all. If I recall correctly, they sold ok in Canada but the majority of sales came from Europe (Germany in particular). Out of all of the models the Atari PC3 (8088 XT) was the most popular and just happens to be the PC I had all those years ago which is how I came to know of them all the way over in Australia. :D

the atari and commodore pc's are really nice. they offer some different approches/solutions for basic PC-stuff like the gfx-chip,
but as for design, no old machine looks as nice as the "schneider tower-at series computers" :)

What a coincidence that you linked to my picture. I just upgraded that Schneider to 16 MHz. :) Once it also got an 80287XL, it will be the perfect AT.

we should talk about:
- your 16mhz Mod (Cpu-Cycles/Board are controlled by Bios, so options are 12,5/6) http://retro-net.de/58.html
- the usage of the "EURO_EMS.DRV" http://forum.classic-computing.de/index.php?page=Thread&postID=82036#post82036
- my System70 (386sx16) had a Upgrade-Board on the Onboard ATI (it added 256k VRAM => 512K Vram), but is that CEG ?
- I removed it from the 386sx16 and put it in my 286/12,5 so I got 512K Vram in it, but 640x400@256Color is max :(

++EDIT++
My 286/10/EGA has Win2x,Win2x,Win3x, Gem1.x, Geos1.x and many Games installed...a fantastic machine. I love it!
I should find a way to configure Win1x/Win2x to use EMS, but that does not work yet.
My 286/10/EGA has 4 Sim-Slots, but only 2MB are possible. https://www.flickr.com/photos/94839221@N05/albums/72157657434520533
What Mousedriver and Port do you use? I activated the mouse-option in the Bios and use the original schneider-bus-mouse with the old msmouse.sys (version 6.02) The mouse works everywhere including Win1x/2x/3x :)

The 16 MHz mod is actually quite easy. I installed a Harris 80286 cpu with 20 MHz and replaced the 25 MHz quartz crystal with a 32 MHz one. The BIOS must be set to 10/5 or 12.5/6.25 (it won't show 16/8, as it simply doesn't know about it). 16 MHz is the maximum supported speed by the Headland chipset on my CPU card. Unfortunately, the only drawback so far is that I had to disable the parity checking again, as the parity chips I installed before are not fast enough for 16 MHz.

"EURO_EMS.DRV" doesn't sound as it's meant for the Tower AT. Never tried it, however.

The ATI in my Tower has that upgrade board as well. But that's really just another 256k. CEG is a special mode of the VGA Wonder-16 chipset. How to use it? I don't know. I guess there was a driver disk that contained a Windows 3.x driver to use the CEG mode, but I don't have that disk. Currently, I don't even have Windows installed - only MS-DOS 5.0 and some games/tools. :D

I have a serial mouse attached, since I don't own the Schneider bus mouse.

ps: might be a better idea to discuss this further in a new thread?

More like with the Atari ST to STE evolution: same amount of colors but choosable from a bigger palette.

Yes it crazy what some will do. Like the people that strip the badges off their Neon's and put Mercedes c320 or whatever model Mercedes they think it looks like. Actually saw one on craigslist last year that was listed like that. 2002 C320 'neon' for like 4K. I called the seller several times and just laughed on his voice mail.

the reality is, and I'm a fool for not saving the photos of the item, if it were used internally by Atari, even if some goon in the company slapped an Atari logo on a vanilla clone w/gum or whatever, it's still *kind* of interesting. Sure would get a few howls from former employees if they saw it.

The Atari ATW Transputer Workstation prototype was built in an IBM PS/2 tower case, so maybe Atari employees did have a habit or reusing IBM parts.

I am new here "first post" I registered here because i have a lot of older PC cards for sale, but I saw this Atari thread and started reading, and maybe you would like to see my Atari pc4 :) some picts :

If interested I could post pictures of the 3 plug in cards that are inside. And sorry the big AMD sticker was on it when I got it :shock:

No, it's not PS/2 (model 80/90/95) chassis, it's ATARI's own home made tin can.

Just for your reference, I am now a proud owner of an ATARI PC3. It's fully working and after just studying the user manual, I am even more happy to have it, it is technically a good machine.
