jacobus Posted July 18, 2015 Share Posted July 18, 2015 I was recently sorting through spare 400/800 components and noticed the numbering scheme used on the major components. I've identified 9 of the 11 possible boards (as follows), but I cannot find numbers 6 or 8. Can anyone tell me where they can be found? 1 800 mainboard 2 800 power 3 8K RAM 4 400/800 OS 5 400/800 CPU 6 ? 7 810 controller 8 ? 9 400 mainboard 10 400 power 11 16K RAM Quote Link to comment Share on other sites More sharing options...
Bryan Posted July 18, 2015 Share Posted July 18, 2015 Maybe it's the rest of the 810 boardset? Quote Link to comment Share on other sites More sharing options...
jacobus Posted July 18, 2015 Author Share Posted July 18, 2015 Maybe it's the rest of the 810 boardset? That was my first thought as well, and you well may be right. However neither the 810's power board nor the controller's daughter board are numbered. I checked the 850 and 835 and they don't have the same sequence numbers.

Rybags Posted July 18, 2015 Share Posted July 18, 2015 Possibly PAL versions have unique numbers. In that case that would need one for the CPU board, maybe one for the OS board, although there's no requirement at all for different board layout, only the 4K Roms are different.

+DrVenkman Posted July 18, 2015 Share Posted July 18, 2015 (edited) One of those might have been planned for the 4K RAM board initially planned for the 400. *shrug* Interesting to see the boards all laid out in a list like that, however. This would be a good question for a guy like Joe DeCuir. If people here weren't so allergic to Facebook, someone could post this in the Atari Museum group there (Curt Vendel and Marty Goldberg's group) and ask him.

There are a bunch of things I'd love to have facebook for, but I watch all the crap from friends and family on my wife's page and I say, "No, thanks!" It's much easier to like people when you don't have to be witness to their inner dialog. Plus, I don't trust that idiot Zuckerberg with any of my data. It would be cool to see if Atari had assembly line manuals that reference the numbers. 1 Quote Link to comment Share on other sites More sharing options...

It would be cool to see if Atari had assembly line manuals that reference the numbers. Trust me, I understand. That said, I've found the use of FB Groups to be a very good way to connect with a lot of people across the world who share the same hobbies and interests. Among those is Atari - a lot of ex-Atari programmers and hardware dev types (for instance, the above-referenced Joe D.) frequent or at least drop into interesting threads in the Atari Museum group. They, or Curt/Marty, would be the ones likely to know the answer to this kind of question and provide documents like that, if they still exist.

It looks like the original 810 powerboard was numbered. Jacobus must have been looking at the revised version. Quote Link to comment Share on other sites More sharing options...

I wonder if the daughterboard on the controller is #6 (on older units) Quote Link to comment Share on other sites More sharing options...
Bryan Posted July 20, 2015 Share Posted July 20, 2015 Awesome! Thank you! I wonder if the daughterboard on the controller is #6 (on older units) I think they called that the Data Separator. Are there any other peripherals Atari made in house? The boards for most peripherals came pre-installed from other factories (printers, modems, 410's, etc...). Does the 850 have a number?

tep392 Posted July 20, 2015 Share Posted July 20, 2015 #6 is the 820 PC board. I don't have a pic of it but here's a page from the service manual. Can anyone find a 12? Quote Link to comment Share on other sites More sharing options...
Bryan Posted July 20, 2015 Share Posted July 20, 2015 Ah, I'm guessing that means there's a good chance Atari assembled 820's in house. Find the PCB's is the secret forgotten Atari game! Quote Link to comment Share on other sites More sharing options...
jacobus Posted July 20, 2015 Author Share Posted July 20, 2015 #6 is the 820 PC board. I don't have a pic of it but here's a page from the service manual. 820 circuit board diagram.jpg Can anyone find a 12? Great catch! I pulled apart my 820 and confirmed this. I wanted to design a display using all of the numbered boards in order - unfortunately I don't seem to have an old 810 power board, and I only have the one (working) 820. Does anyone have either of those boards that they want to part with? Quote Link to comment Share on other sites More sharing options...
jacobus Posted July 28, 2015 Author Share Posted July 28, 2015 Thanks to Bradley at Best Electronics I now have a complete set! 1 Quote Link to comment Share on other sites More sharing options...
