nice setup

It look like they haven't customized the icons and fonts yet (window's closer is also the same as on the PC-GEM). PC-GEM has two icons sets: DESKHI.IMG and DESKLO.IMG. Atari decided to use only one icon set, my guess is that due to ROM size limitations: 192kB. I read somewhere that initially the plan was to use smaller ROM in the ST: 128KB. Regarding CP/M and GEMDOS, below is a screenshot from Atari Corp. book before GEMDOS was born: I heard that GEMDOS was initially a private project one of the DRI employee - Jason Loveman and was called "Jason DOS" / "Project Jason" and it was DOS 2.x based. Therefore history has come full circle: DRI CP/M --> SCP 86-DOS/QDOS --> MS DOS 1.x --> MS DOS 2.x --> DRI GEMDOS Ok I've found that article: http://cd.textfiles.com/crawlycrypt1/program/books/progem/gemdos.15 There you can find GEMDOS vs DOS vs CP/M comparison: https://docs.google.com/spreadsheets/d/12XHJ6YHRDfvNhtnlzEINBjRRXZPKvDQgI7AI424oTws/edit?usp=sharing

why mono-spaced spacing fonts? because it's faster - each letter (8x8 or 8x16) fits in its own byte in memory, so you just need to copy the font data from the source to the destination. Whereas with a proportional font, each letter must be also ORed and shifted in the destination memory. Btw. GEM supports proportional from the beginning (this is GDOS in Atari world)

GEM (on both platforms -PC and Atari) and Amiga OS used mono-spaced fonts due to performance issue.

These fonts look cool, what's their name (menu, icon, file list)?

Sony mentioned Atari Falcon 040 and Atari Falcon Microbox 030 in its design patent: https://www.feedme.design/was-the-playstation-2-design-really-based-on-an-old-atari/

"Is this a good system?" Yes, it is.

I've heard about hair dryer and screen heating

my way was 800 XL -> 1040 ST --> Falcon 030 --> PC partially in 1999 same with me, my /|\ are in the shelf behind me

BTW Is it scam? https://bestshoperss.top/products.aspx?cname=atari+jaguar+shell&cid=273

interesting story what was that name? do you know what hardware changes were requested?

nice one, is there a schematic of the right board available somewhere?

for me Atari ST mini sounds interesting.

TOS on the cartridge - sounds interesting, would be cool to find it. It seems it is a bit different than the final one - I see PC GEM icons, and the Desktop is surrounded by the black border Where did you find it?

both files contains Icons: e.g. PC GEM 1.1 in 640x200 mode (picture below) uses icons from "DESKLO" file:

I see that some .ASM functions are called from IBM.C

unfortunately 192 / 384px per line is just Atari's b/s marketing. The real result is 352px (or 356px thanks to Mono) in Hires per line and half of that in 4 color modes.

"GEM Desktop 1.1 was released on 10 April 1985"

GEM screen resolution depends on the capabilities of the graphics card, at that time (1985) 640x200 was quite popular. I see there https://www.seasip.info/Gem/Drivers/video.html drivers for GEM 1.x for e.g. Hercules 720x348 Actually PC GEM 1.1 in 640x200 wasn't so bad: Digital Research Inc designed GEM in that way that, based on XEROX experiences. Regarding green desktop, if I remember correctly the first 16 colors in GEM were standardized by Digital Research. Blue was reserved for PC GEM, therefore Atari didn't have much choice: PC GEM: ST GEM:

no, different pin layout STE: 5200:

obviously 120fps is better than 60 but in retro computer world we have used to live with 25 and less fps.
