DavidMil Posted December 10, 2018 Share Posted December 10, 2018 It was a version of MyDOS 3.05 that supported the 256K upgrade for the old Atari 800. This upgrade worked seamlessly with with SynFile+ and Syncalc. When you booted either of these two programs they would say "288K RAM Present". It also gave you a 946 sector double density RAM disk. Ross Beers created this version and it was originally put out by LAACE BBS under the file name MYDOS256. I ask this because I came across the RAM and ROM board upgrades while I was looking for a still AWOL 600XL system board that I got angry at a long time ago and shelved. As I recall this upgrade worked well with Omnimon! when I wanted to load a whole disk to be; well, modified (some would say hacked). Any help would be appreciated!

Mathy Posted December 11, 2018 Share Posted December 11, 2018 Hello MrFish Thanks! I already uploaded the ROM file to my site and have changed the layout a wee bit. I don't know how to test the ROM so I haven't tested the file on "autocorrection by downloading on anything else than an Atari 8 bit computer".

_The Doctor__ Posted December 11, 2018 Share Posted December 11, 2018 (edited) Hey Mathy, your mydos page says "This picture I found on http://atarixe.dotnet.lv/DOS/MyDOS.htm. The site was in Letvia. I'ld have loved to know what was being said on this page. Unfortunately, the site seems to have disappeared."... https://web.archive.org/web/20011221134459/http://atarixe.dotnet.lv:80/DOS/MyDOS.htm it says The MyDOS 4.53 operating system was developed for Atari microcomputers in 1988 by WORDMARK Systems (developed by Charles Marslett and Robert Puff). The latest version is 4.53. The system was developed based on Atari DOS 2.x and inherited from it a shell-menu with commands. However, the interface of this operating system was more user friendly. Also this system was very well compatible with DOS 2.x programs and floppy disks. Single-sided single-density discs of 40 tracks of both systems were compatible with each other. Also MyDOS allowed to read disks of the expanded density of the DOS 2.5 system. The system supported single-sided and double-sided floppy disks in 40/80 single and double density tracks. Also, support for hard drives up to 16 megabytes in size and built-in support for a RAM disk were built in. The system still allowed to place up to 64 files in a subdirectory, but it was possible to create subdirectories. Each subdirectory allowed to place inside another 64 files or subdirectories. You could rename any executable file to AUTORUN.SYS. Then it automatically loaded when the system rebooted. Basic devices are the same as in DOS 2.0s. To work with a RAM disk, hard disks and high-density floppy disks, the system needed to be configured. The new configuration was remembered on disk and was restored automatically upon reboot. For the MyDOS operating system, Norton Commander was developed - a similar shell - Toms Navigator (the system command processor was replaced - the dup.sys file): I do not see it other than a russian dialect translation of what know.. any specific part you are looking for?

+Larry Posted December 14, 2018 Share Posted December 14, 2018 Re: MYDOSPLS I downloaded Tim's file, and it shows no file type under Windows. But after looking at the file from the Atari screen editor, it says it is a patch file to convert MyDos 3.015 to MyDospls. So (assuming that the file works properly), we would still need 3.015. I have 3.013, but not 3.015 (and I didn't try 3.013). There are so many different early versions of MyDos... Edit: I did try it with MyDos 3.013, and it fails -- it appears aware that it is not 3.015 in D1:. The patch file does load and run, but terminates with an error. We're going to need to come up with 3.015. 3.015 is mentioned in this thread (including "Archive Copy"): http://atariage.com/forums/topic/169735-sweet-8-bit-haul/ Re: MyDos 3.116.rom -- I've never seen this one before -- for the elusive ROMDOS setup? -Larry 2 Quote Link to comment Share on other sites More sharing options...

Thanks, DavidMil Interesting you mention this, because... I remember testing SynCalc on Incognito (from the ORIGINAL bootable-disks), as well as the .ATR images available on-line, and when configuring Incognito on Colleen Mode, with AXLON (1 Mbyte) expansion active, and then booting SynCalc for 800, directly, it recognized the memory entirely on its own (you could see it by the # of cells available)...

Timothy Kline Posted December 15, 2018 Share Posted December 15, 2018 Hello guys What is MyDOSpls? You can find an ARC file that will build 3.013 for ye' on my MyDOS page. Sincerely Mathy Hi there, Mathy, That was the file closest to what David was describing that I could find in my Atari archives here, and my hope was that it would help him get closer if the actual MyDOS version didn't turn up. The patch file would help someone (I hoped) see what needed to be done to add the feature into subsequent releases of MyDOS, too. Beyond that, I think MyDOSPls falls into the FWIW category. --Tim Quote Link to comment Share on other sites More sharing options...

If you have an IDE+2, be careful of these files. I booted these with the IDE+2 attached (holding down SHIFT, I think) and by doing that, it clobbered the HD partition. I had to set the HD up completely from scratch, partitioning and everything. I'm not sure what happened, but it was working perfectly before I booted, then nothing. Yes, I know they are for an 800, but I wanted to see how it behaved, loading into an XL. Now I know... -Larry Quote Link to comment Share on other sites More sharing options...

+Larry Posted December 17, 2018 Share Posted December 17, 2018 Rev d. I don't know how it happened, but when it loaded, something took out the whole partition. Just thought of this -- that computer does have a 65816 in it. Quote Link to comment Share on other sites More sharing options...

1050 Posted December 18, 2018 Share Posted December 18, 2018 The 800 RAMDisks don't use PORTB (it's too busy controlling the other two joysticks for MULE). Yes, but most of the 800 ramdisks are using 0xCFFF as their control register. Only a few early ones were built using the Byrd type but with 0xD7xx as the control register since 0xD7xx is available so easily on the 800.
