ataridave Posted September 27, 2009 Share Posted September 27, 2009 I've been looking for a place to download this rom, but cannot find one. But this again raises the question of legality-why aren't the author's of certain emulators allowed to provide you with certain roms??

I've seen it around-- you might be able to find a link somewhere in this forum-- but I've never seen a copy that actually *works*, at least not that I could tell.

CPUWIZ Posted September 27, 2009 Share Posted September 27, 2009 Wouldn't this work? http://sourceforge.net/project/shownotes.php?release_id=64318 Quote Link to comment Share on other sites More sharing options...
SeaGtGruff Posted September 27, 2009 Share Posted September 27, 2009 It's here, among other places. And I take back what I said about it not working. I guess I've never tried it with the right combination of emulator settings before. I tried it again with 48K memory and no AtariBASIC, just the disk image that has the Level 9 Colossal Adventure game on it, and it *does* work! Every time I tried before, it just crashed the emulator, so I must have had some setting set a certain way that was incompatible with OS A.

SeaGtGruff Posted September 27, 2009 Share Posted September 27, 2009 Wouldn't this work? http://sourceforge.net/project/shownotes.php?release_id=64318 That doesn't seem to have OS A in it, just OS B and OS XL (plus other files, like DOS and BASIC). But OS A can be found at the link in my other post (click "here"). Michael Quote Link to comment Share on other sites More sharing options...
SeaGtGruff Posted September 28, 2009 Share Posted September 28, 2009 I checked the values in addresses 65527 and 65528 on all of the OS ROMs, and I have an NTSC OS B and a PAL OS A. Is there an NTSC OS A anywhere? And from what I've read in the FAQ, the PAL OS B seems to be hard to find (if it's ever been dumped, that is). Also, some of the other revisions seem to be bad dumps.

Michael It's been a while since I've messed with the Atari 8bit emus but I think that's right. OS-A is PAL and OS-B is NTSC. I don't think the other two exist (OS-A NTSC and OS-B PAL) other than protos. Mitch Quote Link to comment Share on other sites More sharing options...

I don't think the other two exist (OS-A NTSC and OS-B PAL) other than protos. Mitch There should definitely be an NTSC OS-A somewhere, because it certainly does/did exist in real life. Likewise with a PAL OS-B, or for that matter, NTSC and PAL versions of the other revisions. As to whether the NTSC OS-A was ever dumped to a ROM file-- I would expect so, because the FAQs make it sound like a dump does/did exist out there, somewhere, sometime. On the other hand, the FAQs do indicate that the PAL OS-B seems to be "missing," presumably meaning no one has ever dumped it to a ROM file.

+Mitch Posted September 28, 2009 Share Posted September 28, 2009 I think the source code was found and a BIN was compiled that way for NTSC OS-A. I don't know if it was ever "released" though. Mitch Quote Link to comment Share on other sites More sharing options...
Kr0tki Posted October 5, 2009 Share Posted October 5, 2009 I think the source code was found and a BIN was compiled that way for NTSC OS-A. No, it was the PAL OS-B that was recreated that way. It was released somewhere in the Atari 8-bit section. Get all the other ROMs here. Quote Link to comment Share on other sites More sharing options...
ataridave Posted March 21, 2010 Author Share Posted March 21, 2010 I've been looking for a place to download this rom, but cannot find one. But this again raises the question of legality-why aren't the author's of certain emulators allowed to provide you with certain roms?? Ok, I've installed Atari 800 emulator again, and am having trouble finding the OS B and XL/XE roms-could someone please tell me where to find these? I found one set, but the OS B rom was PAL. In any case, the emulator was telling me they weren't installed properly. Sorry about this. Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 22, 2010 Share Posted March 22, 2010 NTSC OS-A is in the same bucket as Basic A and B, ie - why would you want to install a known buggy piece of software when fixed later versions are better. Sure, there is probably a few titles that only worked on it, but they would have been fixed long ago. Quote Link to comment Share on other sites More sharing options...

I apologize if I came off as jerk, all of you have been a big help! Question-I am using a joypad for a controller, but I can't (at least with Defender) figure out with this emulator what key to press for a bomb, or how to select a different difficulty level.

Kr0tki Posted March 24, 2010 Share Posted March 24, 2010 Which emulator? Atari800? F2 is Option, F3 is Select, F4 is Start, and the rest of the keys should be described in the USAGE textfile. Quote Link to comment Share on other sites More sharing options...

AtariDude Posted September 17, 2013 Share Posted September 17, 2013 I am hoping that someone can help with this question. I downloaded the Atari800MacX and I can bring the Atari memo pad. I would like to be able to bring up Dos 2.5 but I can figure how to get it to load the ATR image that I have to load Dos. I would like to be able to play the Robot Demo but cant figure out what I am doing wrong to get dos to load. Anyone know what I might be doing wrong?

Thanks for trying to help, but please be careful when making such bold statements. That archive is a mess - it is missing some prototype 1450XLD OS-es and quite a lot of custom replacement OS-es, and also contains misnamed files, bad dumps and duplicates.
