Here are the numbers, in exact order as printed;

C101688-002

ATARI 1987

RP2A10

38 BL2 46

 

This system looks like it was never used, the board is perfect and the housing looks new. I couldn't even find a scratch! Works great. I was going to keep for myself, but wonder what it would be worth if I listed it since it is a rarity? Maybe I could be the next "Tanner?" LOL.

 

I found this post while trying to figure out these numbers. I own 2, all the numbers are exactly the same except for the last. I have:

38 BL2 48

38 BL2 49

 

The Rev 3 board LittleJoe owns has a different chip. It's hard to read but looks like

C101688-001

ATARI 1987

RP2A10

38 7CE 53

 

That 38 could be a 24. The E in 7CE could be a 1 or an L or I maybe. The 3 in 53 is also blurry.

@skintigh

Here you go. Be aware that the board that is inside my jr. is a replacement board. I checked the board that was originally in this jr. and it had multiple chips on it.

 

Thank you for the speedy reply!!!!!!!!!!!!!!

 

I was not expecting it to look so much like "81." 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? Could happen

Serial # A1811979907

 

@The Mr. Video

Could you do me a huge favor and double-check that number for me?

 

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.

Some more, plus I'm maintaining a list of just the last year or so here: 

 

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

The potential pool of 1-chips gets slightly smaller, looks more and more likely 2009309 was a fluke/repair/RMA.

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Found a highish number on ebay, probably the last 195xxxx I add.

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Another high serial # 3-chip, seems like my 2009309 is a fluke and there are less 1-chips than I thought  

Also, the stamped number is out of order again. I'm thinking those must be stamped at the time of shipping, and maybe the serial numbers are even put on the boxes first.

 

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

New finding of interest: a 3-chip in between 1-chips. Starting to seem like my low # 1-chip is an outlier, perhaps a repair/refurb.

 

This finding has been modified for a composite video output, so I guess they removed the RF shield, but the board appears to have the waffle pattern so I think it's a 3-chip.

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Added some notes, links to sources, and adjusted formatting of the table.

Also saw what might be the lowest serial number yet on ebay

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

some more 3-chips, added 1 to the table

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Another out of order number: 3-chip, 8C 2005540 

 

Also, I'm now editing the first post with all new info!

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Confirmation 96/95 2009309 is another out-of-order 1-chip.

 

Looks like 96 from afar, 95 up close. But maybe that random blue line makes it look like a 5? Mathematically, 5 makes more sense as the serial number is halfway between a 93 and 97, but that's not many data points to go by.

You can ask the moderators to allow you to update the original post forever if need be. 
also make sure you are reading B vs 8 and 3 vs 5 correctly. 
 

I ran into a lot of ink smears and blurry faded numbers in the 1200XL list I maintain.   And don’t expect the serials to be sequential but the can be an indicator of another error.  
 

the 7800 serials get really wonky in the latter years. 

I managed to find one moderator and asked, no reply. No idea how to find others, and search doesn't help.

Sorry I missed this post before. Yes, exactly. I think I have this one already from the ebay post, but I'm double checking. Thanks!

I would suggest folks crack open the questionable units to really validate they are 1chip.  I wouldn't trust the case cutouts for the POT as identification.  On the 1chip version, is the POT hole (hah pothole) still there, and just the POT missing?  It looks like just the POT is MIA, so that might be the best indicator w/o opening up units.

 

Since you have two 9B units so close in serial... open them

 

I'm IDing them by the RF shield and circuit board visible through the vents. I don't own the low 9B units but both are confirmed 1 chip.

[Atari Jaguar Bubsy CIB - $75 Shipped]

Is the serial number 9B 2038237?

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

More serial number shenanigans...

 

97 2025558 is clearly 3-chip: 

96 2009309 is clearly 1-chip?!?!?!?

If true, that could potentially double the number of 1-chip models out there. I'll find out if it's really a 1-chip in about a week  I bought it untested, wish me luck.

I spotted a new, even lower numbered unit! And it's also 9B, before 98...?!?! Maybe someone used the wrong stamp in August for a while and didn't notice because it's similar to 98? Or maybe I misunderstand the meaning?

Found a new one on reddit! This expands the serial number range a few thousand, but it also throws in a wrench. 9B should mean it was made in 1989 in Nov, yet the serial number comes before 98 which is August. Did they use the wrong stamp? Reordered serial numbers?

[Compiling 2600 Jr. "Unicorn" 1-chip serial number list, please help!!]

Another spotted on ebay:

A1 8B 1929476

I assume it's 3-chip, can't tell.

I figure if nothing else, collecting these numbers will let me figure out how many units they made in the final months. Right now it looks like in 9/89 they made >28000, but in the lower 20ks in Nov + Dec. Then maybe 15k by 3/99 falling to 11k by the end of the year and Jan 1990.
