lbaeza Posted July 30, 2005 Share Posted July 30, 2005 Hi I just bought Gorf and Demon Attack, two excelent cart games for the 400 and 800. Just for curiosity, I plugged Gorf on my 800XL computer, but nothing happens on the screen. I know some old games have compatibility issues with the XL/XE computers. I'm sure this must be the case. This issue led me to the next questions: Can I replace the XL's original OS with a 400/800 OS (A.K.A. OS-B) ? Will the XL launch Gorf after I replaced the original OS?

Greg I Posted July 30, 2005 Share Posted July 30, 2005 Have you tried usining the Atari Translator disk? This will allow you to load the earlier 400/800 OS in memory and should allow these carts to run. Quote Link to comment Share on other sites More sharing options...

I have 4 OS in my XL one of them is the old one and I never had a problem running 400/800 only games (except if the need 4 joystick ports of course).

Excelent! One question before I put my hands to work. What are the other OS's? I know you must have one XL OS and a 400/800 OS. But what about the other two? One of those must be MYIDE OS, I bet...

lbaeza Posted August 2, 2005 Author Share Posted August 2, 2005 Update Tonight I programmed the 400/800 OS (OS-B) in a 27128 EPROM. I put this EPROM into the 800XL, turned it on, and it didn't work The XL refuses to launch with a OS-B on it. I have some questions about it, though. First thing I noticed is that OS-B is only 10KB, but XL-OS is 16 KB. So, there are 6KB 'unused' on the EPROM. The XL-OS pinout is the same as the 27128. Should the OS-B (10K) be programmed on a 27128 (16KB) EPROM? Or should be used another kind of EPROM? Is the pinout of the original XL-OS ROM the same pinout of the 400/800 OS ROM? Any comments are welcome. Regards Quote Link to comment Share on other sites More sharing options...

Any comments are welcome. Regards 902803[/snapback] The 800 OS is a 24 pin ROM where the XL is a 28 pin. I think the only way you are going to get the 800 OS in the XL is to get AtariMax's 4in1 or 32in1 OS upgrade. It is a flash rom upgrade that houses up to 32 different 8it OS's in one chip. You select the OS you want by booting while holding the select key down. It will then give you a menu of OS's to choose from and the 400/800 OS is one of them. Once selected, it will continue to boot with the selected rom until you change it. The 4 OS's in the original 4in1 upgrade were: APE Warp+ OS Your standard XL/XE OS A public domain Atari 800 Compatible OS for running those 800 only disks and cartridges Your Standard XL/XE OS w/ Reverse BASIC Feature The 32in1 has an amazing selection of OS's including the 4 above.

lbaeza Posted August 2, 2005 Author Share Posted August 2, 2005 Hi By the way, I tried both PAL and NTSC versions of the OS-B on my XL with no success....Help! Regards PS: My guess is this problem is due to the fact of putting a 10KB binary in a 16KB EPROM. What should I append to the remaining 6K? Append zeroes to the binary? Leave it blank? Append the first 6K of the binary file? Help! Quote Link to comment Share on other sites More sharing options...
+warerat Posted December 26, 2005 Share Posted December 26, 2005 If you're using the OS-B 10K binary image, you must offset the start of data. That way you're starting at $D800 which is where the 800 OS starts, as $C000-$D7FF are unused (EPROM absolute addresses $0000-$17FF). So in your EPROM burning software, make sure to load the binary file at offset $1800. I've done this on my 130XE. Use a 27128. Quote Link to comment Share on other sites More sharing options...
kevin242 Posted December 26, 2005 Share Posted December 26, 2005 (edited) I understand ho wyou could run translater and load a binary executable of Gorf, but just how would you go about getting that cartridge to work?

Rybags Posted December 26, 2005 Share Posted December 26, 2005 As I remember it, Gorf ran fine on my XL. Although I have it as a binary file so it's probably been hacked/fixed. It would be theoretically possible to just load the translator then insert a cartridge, but I don't know if it will work. Quote Link to comment Share on other sites More sharing options...
miker Posted December 26, 2005 Share Posted December 26, 2005 Hmm... Is there any use for 32-in-1? Just asking. (for me 4 systems + latest QMEG-OS is really enough). Quote Link to comment Share on other sites More sharing options...
drac030 Posted December 27, 2005 Share Posted December 27, 2005 (edited) (for me 4 systems + latest QMEG-OS is really enough). For me, two systems are enough: the XL OS and the so called DracOS. XL OS is only a rescue OS in this setup. I really don't know an *useful* program which would require the 400/800 OS. The only one I ever knew was EASMD. But MAC/65 is a better replacement and it doesn't require translator disk. I suppose that it is better to search a working replacement for old crap 400/800 OS dependent software, than install 32 OSes out of what 31 will never be really used.

Rybags Posted December 27, 2005 Share Posted December 27, 2005 Converting software to be XL compatible is easy anyway in most cases. Illegal OS calls are easily found and fixed. The only other real issue would be code that writes into PORTB, inadvertantly changing the memory configuration. Quote Link to comment Share on other sites More sharing options...
miker Posted December 27, 2005 Share Posted December 27, 2005 (edited) Ok, then maybe someone has fixed games like Shadow World or Speedway Blast to work on newest OS-es. I still see no real use for the one mentioned above... Edited December 27, 2005 by miker Quote Link to comment Share on other sites More sharing options...
ijor Posted December 27, 2005 Share Posted December 27, 2005 Perhaps just for the record, but I should note that some programs (at least in their original form) require a true 400/800. No translator (disk or ROM based) helps. . I suppose that it is better to search a working replacement for old crap 400/800 OS dependent software, than install 32 OSes out of what 31 will never be really used. I have a hard time understanding this position. You are talking about “installing 32 OSes” as it would be a problem. Yes, you probably will never all use all the OSes. So what? You aren’t actually “installing” multiple OSes in the sense that this means for a PC. You don’t need any more work to install this than any other multiple OS ROM upgrade. It doesn’t take more space on disk or more RAM. It is true that for most of us, 8 or 4 instead of 32 would be more than enough. But Steven’s price is more than reasonable. And a smaller version, with less OSes, would probably reduce the cost and price in a very small amount to be significant. Quote Link to comment Share on other sites More sharing options...

Yes, you probably will never all use all the OSes. So what? So this means that having 32 ones is useless from the point of view of an Atari *user*. I don't think that if your software requires more than 1 OS, you can construct any useful and convenient environment out of it. This perhaps may be useful for running old software (3 OS-es are enough for this, though, namely OS A, OS B and XL OS), but so far I didn't see a reply regarding the question what old software is so useful, so that you can't find a better replacement which works on the standard OS?

So no harm there, Steve was able to throw in the extras as an added bonus without increasing the cost I should also point out that the OSes listed in that screenshot that have RB next to them are reverse basic OSes. Meaning they are patched so that I don't have to hold down option while booting to disable basic. And that is VERY handy And while it's true that I probaby won't be using an Arabic 1200 OS anytime soon - having APE WARP OS, Omnimon, MyIDE etc alone is worth the price.

And for the "just in case" factor; you may one day come across some unique program that will only work on one specific OS for some reason, it's nice to know you don't have to worry about it and no matter what you want to use, it will work with one OS or another on your computer. Some of them, like WarpOS, are much faster which is good for some things too. Edited December 29, 2005 by Gunstar Quote Link to comment Share on other sites More sharing options...

The blank screen reminds me of when a cartridge is dirty or not plugged in right and you have to play with it (strangely nudging to the side a bit) to work. So my question is... dirty contacts maybe?
