My 400 is PAL, original 16K (now upgraded to 48K). It is a UK-PAL one.

Originally has OS A PAL, GTIA chip.

Now has OS B (NTSC).

Basically, what is the difference between a 400P and a 400U ?

Atari must have been concentrating on the XLs by the time those in the last 2 postings were manufactured going by the serial numbers, only 2123 units in 13 to 15 weeks.

If the FAQ is correct that production of 400's ended in May of 1983, I must have one of the last ones made. As to my second one, the one made in Sunnyvale, there's no telling. And did anyone determine what the second hand-written skinny label means? I have an 800 with one of those as well.

Don't know much about mine, but its stock (except for a 48K upgrade I put in the other day) and I've had it since it was in a box 30 years ago...post-27482-0-39503300-1407468677_thumb.jpg

With that original "16K RAM" sticker and similar markings to that effect on the label, it's possible yours had (still has maybe?) a CTIA rather than a GTIA. Have you checked to see? It would be an interesting anachronism if that's the case.

i doubt it, I'm fairly certain that's what the "G" before "16K" on the label is to indicate.

It is a CTIA, judging from the tests I could find on this forum. (POKE 623,64 does nothing, and the "GRAPHICS 9" loop in basic results in flashing blue-to-black) PS I may have missed it in the thread, but did anyone decipher this type of serial number? 421 1193 doesnt seem to correspond to any schemes I'm seeing.

I just clued into the serial numbers. So production was in 42nd month of 81? I could have sworn we got this in 1980, but it's possible.

42nd WEEK of '81, if the 3 digit code holds true for those "16K" serial numbers. The second sticker there indicates it went into the box on October 25, so that's about right. I thought they'd switched over to GTIA completely by then but who knows?

So jealous. Dying for a CTIA machine. PM if you're ever interested in unloading it.

According to this source, they phased out CTIA around Oct/Nov 1981, so this unit would be one of the last ones with the CTIA.

My emboss reads 082

 

Then 013962 on the official sticker.

 

Last is G 152 AV070285-16 2/17 L40 P on the sticker that almost peeledoff.

 

This is my original 400, and my dad said he bought it around 82 or so, which seems to fit.

 

I haven't fired it up in years as I use a 130 XE mostly with Maxflash carts I made with my faves (and APE when I want to try something else)
