skintigh Posted August 6, 2020 Share Posted August 6, 2020 Oh noooooooooooo!!!!!!!!!!!!!!!!!!! ? This looks like a 3-chip, right? I was hoping 1-chips started around unit #1,900,000 and they made 170,000+. This one I just found suggests they don't start until after 2,025,558 and there were around 45,508 made (if we assume @Ravenprose owns a 1-chip and it was one of the last ones made) Otherwise, we have only confirmed they made 2057527 - 2042053 or 15,474 1-chip units!! That's about 0.75% of total production of Jr.s if the serial numbers can be trusted. Quote Link to comment Share on other sites More sharing options...

Centipede, short rainbow cib, Made in Ireland, PAL, Atari Inc, serial 174AI018412 (console), Atari Inc 1983 On the box is the rectangle for the serial number, but nothing is written into, nor stamped, or even a label, it's clean, like never used for its purpose. Actually the jr was released in 1986, but designed in 1983. I think the Pal Centipede bundle was released from 1988-1992. Quote Link to comment Share on other sites More sharing options...

I think the Pal Centipede bundle was released from 1988-1992. There's lots of evidence to suggest that a number of Jrs were released in Europe during 1984/85, especially since the earliest units on this list were manufactured before the Atari Corp. transition took place and there are a few European members here who can attest to seeing and/or owning a Jr. before 1986. The Centipede bundle is actually the oldest bundle for the Jr., again going off all the evidence found here and elsewhere. Later 2600 Jrs. (mainly those from 1990 onward) came with the CX78s and a 32-in-1 multicart. @Curt Vendel do you happen to have anything regarding the release of the 2600 Jr. in Europe?

I think the Pal Centipede bundle was released from 1988-1992. Those are the release dates for the US. The junior was available at least in 1984 in Europe, and it was produced in Ireland in the "short rainbow" and "black" version. Mine is made in Ireland too, but it's a later version with the smaller box. I got it for christmas 1985.

Glennikit Posted September 9, 2020 Share Posted September 9, 2020 (edited) Hi there, I just bought my first 2600 yesterday: Atari 2600 Jr Format: PAL ( I think, I'm not entirely sure though) Made in: Taiwan By Atari Taiwan Manufacturing Corporation Serial number: A1 784234656 I'm not really sure I follow how these S/N's work. So if anyone has any info on that, feel free to tell. ? Edited September 9, 2020 by Glennikit Quote Link to comment Share on other sites More sharing options...
atariUCLA24 Posted January 24, 2021 Share Posted January 24, 2021 So I’ve got a strange one... All black Jr, but says made in USA by Atari-Wong, which in itself doesn’t make sense. The box I got it with says made in Ireland. I imported it from Malaysia and it included the receipt showing it was bought there in 1986. The PCB is also missing the Atari copyright/rev info, has anyone opened a legit Ireland all black console and seen if they have these markings? My feeling is that I might have found an interesting pirate console, what do you guys think? S/N on console is 100080... 1 Quote Link to comment Share on other sites More sharing options...

A1 81 1979907 is a very interesting number: "A1 81" means January 1988, but "1979907" puts in in the range Dec 1989 to March 1999! Also, there is a chance this could be a super rare 1-chip! If you post a good photo of the entire bottom of the Atari I can check. Quote Link to comment Share on other sites More sharing options...
The Mr. Video Posted May 14, 2021 Share Posted May 14, 2021 @skintigh Here you go. Be aware that the board that is inside my jr. is a replacement board.

I'm half convinced it's still a smudged "91" -- the 8s I've see had a larger circle on the bottom than the top. This has a smaller, squatter bottom, so that says "9" to me. But a 9 doesn't have an indent on the right side, so that says "8" to me, unless there was a very specific dead spot on the inkpad. Or the person stamping it sneezed violently?

+x=usr(1536) Posted December 18, 2021 Share Posted December 18, 2021 Just got my second 2600 ever, and it's another Jr. ? Serial no. is A1 88 1822202 and it's an NTSC 3-chip, long rainbow, totally stock. It will be getting a composite mod at some point, but it's not a priority right now. Interestingly, there were clear signs it had been opened at some point in the past (one broken screwpost, fortunately still held in by the screw; front latches completely gone), but I didn't see evidence of anything having been fiddled with internally. 1 Quote Link to comment Share on other sites More sharing options...
+x=usr(1536) Posted January 22, 2022 Share Posted January 22, 2022 One more for the pile: short rainbow, battered case. Seems to work fine, but switches are stiff and the channel select switch is broken; fortunately, it's jammed on channel 3 which is what we use around here. First job will be a good run-through with contact cleaner and / or Deoxit. Serial number is AT860179710, and it's a Taiwanese NTSC model. Given that it's not in as good of cosmetic shape as my other Jr. is, this one is now the UAV candidate. 1 Quote Link to comment Share on other sites More sharing options...

Those both appear to be NTSC, and I am 95% sure the first one is a very rare 1-chip!! Could you please post photos of either the circuit board inside, or a some shots of the back where we can see through the vents on the back? 1 Quote Link to comment Share on other sites More sharing options...

Hmmmm, I really don't want to open them so I will take pictures of the vents of the back. What exactly does 1-chip mean? Besides being rare is there any advantage to having a 1-chip ?

What exactly does 1-chip mean? Besides being rare is there any advantage to having a 1-chip ? Well, if you want to make a handheld, portable Atari it has an advantage because it's smaller and uses less power. Other than that, I'm not sure, and it's technically worse at audio because it only supports mono, not stereo (which the 3-chip theoretically could support, and a few early games could, too, but then that feature was dropped in production). The 1-chip was a prototype to allow Atari to save money. They didn't make a lot, and towards the end started shipping them as I guess they ran out of other stock. Every 1-chip I have seen is on a "rev 4" board, with one loan report of a "rev 3", but no picture. It's only a few screws to open and easy to do, but if you are hesitant you can take a photo a few feet away (and maybe zoomed a little) so you can see down through the vents, and take a pic, probably a flash would help. Mostly I'm looking to see which side of the vents have a metal RF shield behind them. Thank you!!!!!!!!!!!!! Edit: look 3 posts up, you can clearly see the well-illuminated RF shield through the vents on both side in that Atari.
