I'm relatively new to Atari repair, currently trying to order replacement I.C.'s for my Rev. 16 Atari 2600, but am having some trouble figuring out which labels mean what on each chip. Attached is an image of the chips on my 2600. From what I gather, the C0... label is the part number, but what do the other two(or one in the case of the middle chip) labels signify? And more importantly, do they have any relationship with the type of chip it is?

 

Thanks!

Not quite what I was looking for. I know what each chip does, was just wondering about what the other labels on them, such as the 8242 on the bottom chip above, signified. Thanks though!

Sorry I misread the question.  Some use different numbers for date codes, where it was made, etc.

Alright. All I really wanted to confirm was that as long as the IC # (such as C010444-11D) is the same, they are effectively the same.

Yes, the 8242 you mentioned on the bottom chip is a date code, meaning it was made in the year 82, and the 42nd week of that year if they are using the YYWW format(which they are because 82 wouldn't be for a week so it is YYWW).

Awesome! Thought it was something like that, but wanted to confirm since I'm new to this. Thanks for the info

YW, if you wind up needing a RIOT chip I have quite a few.
