The question is no longer relevant, I myself began to develop the case and board configuration.

Hello. I'm looking for drawings of the Atari 2600 cartridge board and body with all dimensions. If anyone has drawings with verified dimensions, please help. I will print the housing for the cartridge on a 3D printer. I found quite a lot of 3D models of cartridge cases, but I don’t know how their internal configuration corresponds to standard boards. So I decided to make it myself, but this requires all the sizes. Unfortunately, I don't have a single cartridge and can't measure it.

I use AV, but this is a layout and video output is not done very well. When the design is translated into a good PCB, the video output will be done correctly. There will be composite video output and S-Video.

Two years later, I launched the Atari 2600 on a breadboard. No control, only launching games from flash memory and displaying on the screen. Now I'm designing a PCB. I want to place the entire console on a 100x100 mm board. I checked the UM6526 microcircuit, which I wrote about earlier and whose photo I posted. As expected, it didn't work.

I could not find information on the UM6526 chip. I ordered UM6526P1 from another seller. Until I receive the chip, I will not continue to work on replication. When replication is assembled, I will create a separate topic for this. Thank you all for participating! But if someone gives information on the UM6526, I will be very grateful.

Yes, of course, I will publish the progress. But, unfortunately, due to a problem with TIA, the assembly of the project is postponed indefinitely. If the UM6526 can be used, I will continue to work. If not, you will have to order another. Now my Atari 2600 looks like this

If I had an Atari 2600, I would experiment with it. Unfortunately, I can’t buy the original console because of the high prices. Therefore, I decided to assemble it myself and bought chips on Aliexpress. If I have new information, I will write in this thread. Here is a photo of the chip I was talking about:

Thank you very much! Yes, at this link, in one of the messages there is a phrase: "You are right, the UM6526 is not the same thing as the Commodore MOS 6526. Along with the UM 6507, the UM 6532 and others, it does belong to the Atari 2600 chipset. " I will try to find out where this information comes from and how reliable it is.

Can you give a link? Perhaps there is information useful to me there.

Quite possible. But this only says that the seller is bad or the seller deceived me. I now need to know exactly what UM6526 is. If this is a TIA, then you need to know exactly which one - the connection diagram will change. If not TIA, order another chip from another seller.

Thanks, I was on the link http://etim.net.au/2600rgb/installation-jr/ It says: "The PAL version is labelled C011903 or UM6526." But in the photo, UM6526P1.

UM6562 or UM6562P1? C0104444D or CO11903? NTSC or PAL? What does the UM6562 correspond to and what does the UM6562P1 correspond to?

I also found information that the UM6526 is NTSC. But I would like to know for sure, from the one who personally dealt with the console, which included UM6526. From this information it depends on which circuit to connect the UM6526.

Hi all! Instead of the ordered UM6526P1, they sent me a UM6526 (without "P1"). What is the difference between UM6526P1 and UM6526? Regards, Alex.
