Very nice demo!

It most prolly holds software like loader and copy utils to be used with modded tape drives (Turbo) that were widespread in Eastern Europe countries like former GDR, Poland etc..

You wrote the 1200XL was planned to be the big brother of the 600XL. Vendel / Goldberg wrote: 'Work began on the 600XL in the spring of 1983, just a few months after the introduction of the 1200XL computer system.' How can the 1200XL be planned big brother of something that didn't exist during the planning stage of the 1200XL? Logical fault.

That's not correct, I think. According to the book by Vendel / Goldberg the 1200XL was first. The product specifications of the 600XL were finished May 1983, i.e. several monthes later than specs of the 1200XL and even after the release of the 1200XL.

Mathy, did you forget the ?

Kevin, did you ever ask someone in your interviews for sales figures of the 400/800/1200XL computers?

So you relied on consecutive serial numbers with no further encoding?

Michael's version doesn't feature that particular sales figure. So the number 105.000 is indeed not reliable?

Can someone please post how the selling figures I read in the FAQ at Atarimania (105.000) are computed? Just the sum of the highest serial numbers of both production lines? If so, how do you know if the serial numbers given by Atari are consecutive numbers? The list of post one in this thread does not contain any consecutive numbers (at least I couldn't locate any). I am pretty sure Atari tried everything to obfuscate the real sales figures. So I suppose there may be also some gaps - that even may vary on a daily or weekly basis - between serial numbers of computers that have been produced the same day. Any opinions? I posted this in Karl Hellers Atari 1200XL serials thread before, but I think it should be a seperate thread.

It was definitely released: Please check its entry at Atarimania. Unfortunately I sold my sealed Spark Bugs a long time ago

Commercial game carts: Espial, Matterhorn, Spark Bugs, Hypnotic Land, Powerstar

Very interesting, thanks for posting. 'E' for 'Eight bit' and 'X' because it is compatible. So this would clearly contradict with what seems to be the standard explanation (EXtended Line Enhanced) so far.

Please stay on-topic.

Hi, are there any official documents from Atari or magazine reports that explicitly confirm that 'XL' means 'eXtended Line'? Everyone claims it, but I couldn't find any proof.

Nearly all Mastertronic disc games.

Will all these interviews be released in written form as well? A would buy that book...

Wow, a usenet post from 1981 that answers all questions. Thanks ClausB!

Where did you fnd that ad?

Lack of skills? It's easy to put a demo together, but a real game with animation, music and level balancing is by far more complex.

Great work Allan!

Superb!

Someone at ebay is offering an old ad (enlarged to poster size). Please check at ebay 381553428082

I am talking about an external unit. It's not the 128K memory board to be plugged into the 800s extension slot.
