Mr. Undo

Interesting appreciation @Cyprian! So they used the same PC-GEM icons for this proto-TOS. I’m glad that this thread has been reborn, shedding some more light on the subject.

Atari ST first launch and first public demo // Winter CES 1985 A new link for the video I posted here at the beginning of the topic (fortunately the video is still preservated in YouTube)

Thanks! The site is based on a very customized Wordpress template. So, yes, it uses databases. But all the the content is updated manually, entry by entry, in a similar way you publish posts in a WP site. Marty Goldberg pointed me also to this site yesterday on Facebook. As I told him, Michael Current’s work was the starting point for this project. I cite many of the sources that he points to on his site. Michael Current made a priceless research to create those timelines. This decision was made to optimize the loading time. I have to find a better way, allowing a progressive loading without leaving the lightbox (pop-up) mode. The design is still in progress

So far I have the timeline in draft mode until the end of 1986, pending to be adapted and published. My intention is to keep up with the research and expand the timeline up to the end of Atari Corp’s life.

If you have some spare time and you want to delve a bit into how the Atari ST was conceived and its first months of life, take a look at this website I'm working on: http://atarivt.com/

Besides @Allan effort uploading Current Notes to Archive.org (thanks again, man!!!) there are more CN issues uploaded to archive.org by the Atari historian Kay @Savetz(host of the ANTIC 8-bit podcast) https://archive.org/details/@savetz and Scott Stilphens (the man behind ataricompendium.com) https://archive.org/details/@scottithgames As Allan said, it would be great to have all the Current Notes into one section on archive.org. Meanwhile, there is a compilation of all these Current Notes issues here: http://www.ataricompendium.com/archives/magazines/current_notes/current_notes.html, although the following uploads by Allan are not still registered in the page: MARCH 1986: https://archive.org/details/current-notes-volume-6-number-2-march-1986 APRIL 1990: https://archive.org/details/current-notes-volume-10-number-3-april-1990 JUNE 1990: https://archive.org/details/current-notes-volume-10-number-5-june-1990 SEPTEMBER 1990: https://archive.org/details/current-notes-volume-10-number-7-september-1990 NOVEMBER 1990: https://archive.org/details/current-notes-volume-10-number-9-november-1990 DECEMBER 1990: https://archive.org/details/current-notes-volume-10-number-10-december-1990 MARCH 1991: https://archive.org/details/current-notes-volume-11-number-2-march-1991 DECEMBER 1991: https://archive.org/details/current-notes-volume-11-number-10-december-1991 JUNE/JULY 1994: https://archive.org/details/current-notes-volume-14-number-5-june-july-1994/mode/2up

There is a reference to the Atari second disk here: http://captive.atari.org/Main/ReleaseInfo/ReleaseInfo.php "The Atari ST version came with 2 floppy disks even though the second disk is usually not used. The first floppy is a double-sided disk, but in the case where a system is equiped with a floppy drive that only supports single-side floppies, the second disk will be required to read the unreadable side of the first floppy disk. In other words, the second disk is a copy of the second side of the first disk. When the second disk is required, the system will display a request to insert disk two. A way to see it is by removing the floppy disk during the "Federation War" screen (the bouncing lines) and hitting a key."

@SoulBuster Thanks for sharing and the preservation effort!

And this one: Atari Mega STE with 1mb memory and hard disk. Mouse and manual included. Cleaned and tested. Box of floppies included. Sold for EUR 500 / aprox. $604

@calimero You’re right. So, this one: Atari Mega STE 4MB Computer Atari SC1435 Monitor Atari Mouse and Keyboard - sold for EUR 1260 / aprox. $1,522

There is also a C07115 REV 2B PCB https://imgbb.com/7KLXgY3 not listed here: https://temlib.org/AtariForumWiki/index.php/Atari_ST_motherboard_revisions

Maybe I didn’t explain myself very well here. In this case I’m wondering if there’s any other variation (besides the change in ROM) between this specific PCB (C07115 REV 2) and the drawings of the schematics I’m referring in this topic, which are numbered C07112. Regarding PCB versions, you’re right, the list is long. Here is a good compilation, maybe still incomplete: https://temlib.org/AtariForumWiki/index.php/Atari_ST_motherboard_revisions ?
