A1 on a 7800 7= the year 5 = the month your PCB will have a dated ink stamp on the solder side also check the IC dates.

If there doing the A1 serial numbers like the 7800 its May of 1987? thats a super late system those Pcb's are probably the ones Best Electronics has left over from Atari they sell now.

Hi it looks like they added the box to there console wich is perfectly acceptable because there is no serial number on the boxes of 5200s

Hi im adding my CIB 4 port system to the list with my others its a 2nd week of October 1982 system,

I found this one also its close in number 2 my other 7800 no exp port a Dec 1987 unit,

The game boxes from 1984 all got 1986 games inside of them so what does that tell you about the system. A system released with no games? i dont think so no launch games no system it cant sell with just the pack in game i wouldn't think.

I saw a newspaper article stating they would be doing a test marketing in San Fran and in LA the key word is "would be" did it happen? i see no evidence of a test anything other than that ad from 1984 no games other than pole position because that game was in the system box so ya it got made. In my opinion no they all sat for 2 years.

comp modding a low serial is probably not a good idea its worth more OG ill buy the modulator off you if you want to sell it it should have a date code on it from 6/84.

Actually he is wrong the power supply made in Japan grey with black sticker was a Heavy 6 power supply for units serial # or letter in this case J - N and then yes it carried over to the light 6er units.

Hi i have had these 2 AT84's for a while now but the thread was dead for so long i didnt bother to send them glad to see its been updated and in good hands. AT8413423 AT8408385 both have the exp/port

Very nice if you flip the board over there should be a date stamp stating Rev A on it in the corner with week and year. So far 26th week on your serial number is not that old for that low number of 517 unless these Elpaso were not made 1st mine is a 24th week sunnyvale but your PCB mat be dated earlier than the shell sticker.

Sears Heavy 6'er with no channel select and a do not open sticker. 16456-U

Nice G unit mines a G also the motherboard on mine says 10/12/77 so id say yours is October also.
