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.

I welcome everyone. I have a UM6526, UM6532, UM6507 chipset. I want to build an Atari 2600 console version of PAL. The circuit I found contains errors. If anyone has a circuit on the UM6526, UM6532, UM6507 chipset that is correct and that works, give it to me, please. Regards, Alex.
