7800 Serial Number List

[+Mitch]

Do you still have a copy of the old list? I am pretty sure it was on there. Though it is hard to remember any more.

Old List/Post..

 

=====================================================================

I am putting together a list below that will be similar to the heavy sixer serial number list found in the 2600 thread.

Last Update: Post #277

I think the order from earliest to latest consoles is as follows.
"EP" - these were the original 5000 made in El Paso Texas in mid 1984.
"AT84" - early batch still with Atari Inc.
"AT85" - early batch now with Atari Corp
"A1" - initial models still had the expansion interface
"A1" - later models lost the expansion interface
"A3" - next run of the 7800 units
"X" - final run of 7800 units?

If anyone has more information that would be useful in the descriptions above then feel free to suggest it too.

I noticed that in the list that PAL RGB was listed in several different ways. For example: SCART, PAL with RGB sockets and French SCART are all the same thing. It might help to clarify if they are all listed the same way on the list. Also, it might be helpful to list all of the PAL units together instead of grouping some of them with the NTSC consoles. Just a thought.

Got it.  This makes sense.  I'll update accordingly.  Thanks!

Here are my two. One's a mystery! If anyone can give any information on these, particularly the date, I'd really appreciate it. Thank you!

I'll add a section for undetermined serial numbers that can't be attributed to a production run. I want to capture that the system is out in the wild regardless, and who owns it.  Thanks!

[electronicsibley]

The list has now been updated up to post #300, or all the way through page 12 of the thread. I'll update the master list as I make it through each page of the thread. There's a a lot here, which is exciting, but also a ton to sift through. Bear with me!   

[electronicsibley]

The list is now updated up to post #325, or all the way through page 13 of the thread.  Things are moving a bit more quickly now!  

[electronicsibley]

Went on a bit of a tear and completed two more pages of the thread.  It's now current to post #375 on page 15.  And my system is now listed!

Just about to add your system to the list.  Does it have the expansion interface?

@electronicsibley Hm... don't know what happened here.

 

OK I'll repost it.

And, that's a wrap! This list is officially up to date. I do want to go back and verify full-on expansion ports in the A1 units, but otherwise, things should be solid. FWIW, the count now stands at 307 working systems. And those are systems with owners engaged enough to submit them here. Definitely something to keep in mind for anyone developing a game for the 7800. I'll notify of general updates in the 'version history' of the post going forward. Any more systems? Send 'em my way!

Well, do keep in mind that since I added the 2 I had at that time to this list, that my A3 unit with the DevOS BIOS in it, is actually an AT84 mainboard with all socketed chips and has the expansion port as well. I've seen several like this. So the A1 - A3 listing doesn't always mean an expansion port may or may not be present as it would seem Atari was throwing together anything they could fine (Or in my case I suspect mine was a return due to some issue as it shows some factory rework) and then sold out to the masses.

 

That reminds me, I have a 3rd 7800 to add to this list at some point and the initial A1 86 no longer has the LHE inside it. It now has an early rD UAV, with chroma fix circuit in place, UV power LED, RF modulator removed, and new Kiloparsec BIOS installed.

Wow, that’s interesting, and definitely worth noting. Is there any other detail that would indicate outwardly that the expansion port is present beneath the case, like with your system? The fact that you’ve seen several like this makes me think a non-trivial number of these systems were produced. 
 

I’ll update your listings, and keep an eye out for your third system.

[+-^CrossBow^-]

No...not that I've found. You have to simple open up the top cover so you can see if the port is off on the side or not. I've seen very few, but I have seen them, some A3 units with expansion ports on them. I serviced one not that long ago in fact that the date stamps on the ICs indicated it was a late '87 made unit but yet.. it had the port and I believe it had the extra timing circuit as well. I honestly don't know how many 7800s I've seen at this point but it is somewhere around 60 - 70 over the last 4 years now. The good news, is that while I might not take pics of the serial numbers (I don't..). I do take pics of the insides after I've serviced them and can likely go through my archive of photos to try and get some idea. But there still isn't a way to tell from the outside since the area of the port is covered by the bottom shell on units where they installed the port but did not place it into a shell with an opening for one like my A3 I have listed here.

That’s what I figured; there being no visual clues. No need to dig into it too deeply, but if you eventually come up with some data, I’d love to integrate it somehow. It’s an interesting production quirk in any case!

[+-^CrossBow^-]

Okay, @electronicsibley here is the updated stats on my three 7800s that I own here at the ITC.

 

The 'Daily Driver': 72R5BR A1 86 5372310 -

- UV power LED

- UAV rD

- Cartridge sleeve modified

- 7800 Kiloparsec BIOS installed

- No Expansion port

- ICs soldered to the mainboard

- Extra Timing circuit silkscreen on the board but not installed and bypassed by Atari

 

 

The 'Test Unit': 72R4BR A1 7C 5152641 -

- 7800 Kiloparsec BIOS installed

- No expansion port

- ICs soldered to the mainboard

- Extra Timing circuit installed but disabled (C64 clipped)

 

 

The 'Original': 72R4BR A3 98 5227323 -

- This is my original childhood 7800 that I got for my Birthday back in late '88

- Blue power LED

- Expansion port present

- Extra Timing circuit not present (No silkscreen for it)

- ICs all in sockets

- DevOS 1.0 BIOS installed

 

I suspect my childhood 7800 was a factory refurbished unit sold back out as new in late 88 since it does have interior parts of that of an AT84 unit and shows some signs of factory hand soldering and possible rework, but was sold in the non expansion port case shell and with a later serial A3 series number.

 

[NISMOPC]

@electronicsibley as requested...

 

This is my CIB unit with matching serial #'s.

This is my daily that I AV modified using mini jack to RCA. Still has protective strip over banner.

This is the Expansion Interface model with bad tactile switches.

This is standard model with bad tactile switches. I think this one is A1 7B 5085018, but can't confirm that.

And here are the tactile switches I just received today to fix the two units.

updated serial #

[Silver Back]

This is my back up console with no expansion port and an av mod. 
 

And this is my daily driver with the expansion port, it’s got an av mod, the board has been recapped and had new tactile switches installed. 
 

Next time I pull out my childhood console I’ll add it to the list. That one hasn’t been touched in any way.

Thanks! Can you make out what the second blue-stamped number is?  I see '8', but not the second digit.
