  2. Yes, the understanding is that the serial number ending with the 164 stamp should mean it's from the 16th week of 1984. And the "black label" NTSC units with serial numbers starting with 7YJ were manufactured for Atari by Chelco in Hong Kong. I decided to pull out my 3 800XLs and connect them up for video via S-video, and now I'm just further confused. All three of my units are NTSC, one by Chelco, two by Atari Taiwan, and all three have a "weak" nearly black & white signal on the chroma output line. I might describe it the same way you describe yours. Atari's own schematics show Pin 5 on the monitor port to be Not Connected, and so does Sams, but it sure looks like it's connected to something. Do people actually have units with no video on the Chroma pin, corresponding to the schematics? Or do all the units without proper chroma connected actually have this same "weak" chroma on Pin 5? Sorry if this ends up sabotaging this thread, but I sure am curious.
  3. Willing to share the serial number of that interesting 800XL? (and/or at http://atariage.com/forums/topic/132201-800-xl-serial-numbers-secampalntsc/ ) I thought all 800XL units with chroma were later production units under Tramiel, and from Taiwan. I don't know where one from Hong Kong would fit in. It also sounds very much like this old description: https://comp.sys.atari.8bit.narkive.com/ijf7BxNN/my-stock-800xl-has-chroma-output
  4. I have most ST/TT/Falcon launch prices covered here: https://mcurrent.name/atarihistory/tramel_technology.html
  5. Other than the month being off (November, instead of September as reported), this one seems rather plausible: "Science and Math Education Through the New Information Technologies" November 8-9, Tarrytown NY, sponsored by Wicat, Inc.
  6. Just one more issue missing from your list: July 1997 Volume 7
  7. I'm no help, just wondering the details of the connectors on the back of the unit. 1 or 2 SIO ports? Printer port? Slave disk drive port? A photo or two would be excellent!
  8. There's so little info about this drive, will be easy enough to include everything in this thread. The attachment is the ad they ran in Antic for several months. Also, their product announcement mentioned a lineup of four drive models, as reported in Analog: https://archive.org/details/analog-computing-magazine-23/page/n13
  9. Willing to share pics of the rear and bottom? Yes these seem exceedingly rare, first time I've seen evidence of one. Thanks for sharing!
  10. According to https://en.wikipedia.org/wiki/Pascal/MT%2B MT MicroSystems was acquired by Digital Research in 1981. Must be a connection to Atari Pascal finally coming out, via APX, in 1982. Also for reference here: http://www.cyberroach.com/analog/an11/pascal.htm
  11. At http://blog.3b2.sk/igi/post/Napajaci-zdroj-02-ATARI-power-supply.aspx there is a table that lists many Euro power supplies. One of the entries is: FW6799, (no Atari part number), 9.30V, 1.66A, for use with 1010,850,400,800,1200XL This should be the OEM unit supplied with the 400/800/810/822/850 when the 8-bits launched in West Germany in fall 1981. But I have yet to find a pic of this power supply. Do you have one? Could you share pictures of it?
  12. There is "REV 1 June 78" on top of one of the last pages of Version A, making Version A no earlier than that. Near the end of Version B there's a "400/800 Memory Map" that mentions both the 400 and 800 by name. Goldberg/Vendel indicate the 400/800 got their names in November 1978, making Version B no earlier than that. Also, the memory map in Version A seems to indicate a base RAM of 4K, while Version B indicates a base RAM of 8K, reinforcing the time period when they made that decision to bump it to 8K, after June but by the introduction on December 14, 1978. (I think much closer to December, given the "prototype" 800 Operator's Manual that still indicated the 800 was to ship with only 4K.)
  13. Page 6 of the Stewart memo confirms that the Rev B PAL 400/800 OS had not been released as of 1/10/1983.
  14. In my defense, I wrote that based on multiple case reports at the time. People were saying that XLs generally weren't as thoroughly fried by the ingot as XEs were, in their experience. But I've gone ahead and removed the suggestion that the XLs might be somewhat safer than XEs, I think we're better off without it. Thanks.
  15. Not exactly a correction, just pointing out that the summer 1984 transition was messy, making Gremlins and Stargate questionable for your list. There are versions labeled Atari, Inc., but those of us who have tried hard to pin down release dates seem to come up with release dates after July 1, which would mean they were released under Atari, Corp. But perhaps they had been manufactured earlier? Or, perhaps they were manufactured under Atari, Corp. with labels unchanged from their design by Atari, Inc.? Or, perhaps software production continued under Warner for a while before Atari, Corp. really completed the takeover of all manufacturing?
