  1. The entirety of the PC/GEOS operating system, it’s SDK and apparently, ALL of it’s software, have been posted up on Git for community availability and further development ! It appears to be at least PC/GEOS 2.0 and possibly newer. Many files are dated 1991 and many have additional revision dates of “97/04/04 NewDeal” which is at least version 2.5 I believe. Most of the code is written in C and an updated (??) Watcom C compiler is also available from the author on his Git. It was common to write GEOS software with “ObjectASM” in x86 assembly. Their object technology was a key advantage they had over other OSes at the time. You can find the Git repo here: https://github.com/bluewaysw/pcgeos Here is the Wikipedia page: https://en.wikipedia.org/wiki/GEOS_%2816-bit_operating_system%29 …and here is a link to a PDF of the “PC/GEOS System Software Overview”. This document gives an overview of the system architecture and other details for developers. It is specific to ver. 1.0 of PC/GEOS. https://www.lyonlabs.org/commodore/onrequest/geos/PC-GEOS-System-Software-Overview.pdf j
  2. I'm entering that danger zone of the afternoon mental wall, so please forgive me if this has been discussed ad nauseum on the forum to little or no avail... But has anyone ever entertained the notion of coming up with an Atari 8-bit API (Atari Peripherals Index) that mod developers could use to allow programmers to identify add-ins and modifications of any given computer...? I picture it in my head as some sort of index that would work during the boot process, when the DOS or OS would do a cursory check of a pre-determined index in memory somewhere once the mods/add-ins are initialized. Each device would have an assigned API ID that, if found, sends the DOS or OS over to a special table where it would find allocated memory usages, device ID, and any other relevant information that could become accessible to the programmer either through the API vector, or direct (and risk later incompatibilities). This would have the added advantage of allowing multiple add-ins play nice with each other since the index and table assigns/allocates their respective memory addresses. It'd be the closest thing to an Atari PNP operation, too. Just a random brainworm... --Tim
  3. Hi Like the title says, im looking to see if theres a list out there for most of the ones more popularly used and preferably what is unique about them, Ive recently installed Ultimate 1mB on one of my 800XL's and excited about being able to choose a few to have flashed for best results. High speed SIO for loading is desirable but im interested to see whats out there as im sure there's some great ones.
  4. I hate to highjack Sikor's thread, but I'd like to see the results on a single page and tallied up. They only allow for 25 choices, so list your "Other..." if necessary.
  5. What are your favorite operating systems of all time? My top three off the cuff: -DOS: Just because. Simple, and so many great games and programs. -OS 9.2.2 (Mac) The pinnacle of the 90's mac era. So stable, so good.... -Windows 98'-It just worked in that era, pretty clean and smooth and added features 95 was lacking. What are your favorites? Honorable mentions: -Windows 2000 -Windows XP -Max OSX 10.6.8 -Mac 7.5.5 -Atari ST TOS Os's
