Can you tell me what was date it released in ? Thank you, kheller2. The last 3 digits of the serial# are a code for the manufacturing date in WWY format, 143 = 14th week of 1983.

Caterpiggle Posted April 13, 2023 Share Posted April 13, 2023 Thank you BillC, Oh, I c ... that's all I need to know is looking up the last digits 3. That's it . So means it is round in middle of March, 1983. 14/4 weeks = 3.5 months. Quote Link to comment Share on other sites More sharing options...

Caterpiggle Posted April 13, 2023 Share Posted April 13, 2023 (edited) Hello BillC, So my math is wrong ? 14/4 is also wrong ? 1 month is 4 weeks , everyone know that .... I have 1 question for kheller2. Does he posted his title as "IGNORED" On the top of title page " IGNORED 1200XL Owners Club (serial tracker)". So means, it is no longer reappear if it is new post in this box ? Just ignored ? Edited April 13, 2023 by Caterpiggle Quote Link to comment Share on other sites More sharing options...

January and March are 31 days, which makes the total for these 2 months only 1 day short of 9 weeks, add the 28 days for February makes the first 3 months only 1 day short of 13 weeks. This would mean that something manufactured in the 14th week would be at the end of March, or more likely the beginning of April. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted April 13, 2023 Share Posted April 13, 2023 (edited) Seems like it would have been April 2nd thru April 8th if you go by day to week conversion. A week being a 7 day window. It was not a leap year. Or if going by calender week and not days it would have been April 1st through 7th. Either way it's very early April. 14*7=98 days 31+28+31=90 days.

+kheller2 Posted April 13, 2023 Author Share Posted April 13, 2023 The "week of the year" can fluctuate, and I don't think there was an industry standard back then and varied if the week started on Sunday or a Monday. According to my math, 143 would be 4-APR-83 to 10-APR-83. I think I'm using ISO 8601, but that wasn't published until 1988: Week starts on a Monday of the first week that contains the first Thursday of the month (time is such a complex thing). 1 Quote Link to comment Share on other sites More sharing options...

Caterpiggle Posted April 15, 2023 Share Posted April 15, 2023 Hello Kheller2, No worry. Your title finally re-appear in the public forum there. Myself, I don;t know why it is there "Ignored" in red font in first place. Myself, I was puzzled. And thank you for deeper explanation of "143" date birth of my Atari 1200XL. Am I correct, they were made in Sunnyvale, California ? What about in Taiwan ? Name of town were ? Taipei ? Quote Link to comment Share on other sites More sharing options...

Caterpiggle Posted April 15, 2023 Share Posted April 15, 2023 (edited) Hello BillC again, Interesting choice of that site in that city , Tamsui by Atari Company. I used to visit to Taiwan when I was a kid myself. Taipei as well and smaller port on the east coast of Taiwan. I think I found the name of port, Suo Bay. That is the only 1 BIG company ship may dock there on the east coast. Edited April 15, 2023 by Caterpiggle Quote Link to comment Share on other sites More sharing options...
Eric Badger Posted May 2, 2023 Share Posted May 2, 2023 Just received my 1200XL! USA 83S DA 024595 (213) Strange though, no basic in the ROM and no self-test, just Atari rainbow logo. 1 Quote Link to comment Share on other sites More sharing options...

You would be the only person in the world then. You probably had a basic cart in the slot all the time. If not, someone modified it which is an easy conversion to run onboard Basic and the 800XL OS. 2 Quote Link to comment Share on other sites More sharing options...

Had it in the early 80’s. Was store bought. Quote Link to comment Share on other sites More sharing options...

I almost dare to ask if it was a 1400XL but... you said "store bought". Memory is a tricky thing. Quote Link to comment Share on other sites More sharing options...

In the 1200XL, the cartridge does not stick out beyond the casing, and perhaps that is why you do not remember it.
