    Also, I looked at your 6502 assembly language files, and I like what I see-- although I would like to suggest that you add (or consider adding) the compiler directives without the dots in front of them-- e.g., BYTE (or byte) in addition to .byte, etc.-- since DASM will allow either format. Perhaps you can guess that I like to use BYTE, WORD, HEX, etc., without dots in front of them! :)

    Thanks - that's the kind of input I need. I'll take a look at DASM and pull out the corresponding directives.

    I did a bit of searching to see if there were any syntax files available for 6502 assembly editing with Crimson Editor. While I found a couple posts of people requesting such files as well as at least one post by someone who has at least done part of it already, I could not find anything readily available to grab and use for my coding. So, I took it upon myself to start working on one, and the endeavor is also turning out to be a good way to brush up on my assembly while finding differences among various assemblers.

     

    To make a long post short, I have posted the syntax files I created for anyone interested. I welcome any feedback from those of you who use Crimson Editor, and I'm specifically interested in reports of any errors and omissions in the spec. I'll warn you that I started with the 8-bit compilers that I'm most familiar with and am branching out from there in an effort to make the syntax coverage as complete as possible. After a few rounds of revisions, I plan to submit this to the Crimson Editor forums for public comsumption. You can grab it here:

    I have a dead SC1224... Would that back shell work for you?

     

    Let me know.....

    I have an SC124 monitor that works fine, but the rear section of the plastic shell is broken in multiple places. If anyone has one of these that doesn't work but has a good rear shell section, I'd cetainly be willing to take that piece off your hands before you toss the monitor. :)

     

    thanks!

    James

     

    I don't believe it's the same layout - at least it's not for the version of the SC1224 that I have. I appreciate the offer though!

     

    thanks

    Hey everyone - don't forget about the weekly Atari chat tonight. Official gathering time is 8:00pm CST, and you have 3 options for getting in:

     

    - Use your favorite IRC client to connect to irc.newnet.net and join channel #atari.

     

    - Telnet from your 8-bit or other machine to irc.atarichat.net (216.37.55.109) and login as "atari". This will get you into the chat without the need for an actual IRC client.

     

    - Use the Java applet found at http://www.newnet.net.

     

    If you can't make it around 8:00 tonight, or if you would like to stop in other times, feel free to drop in anytime. There are generally a few lurkers hanging around, so you may catch some good coversation at any random visit.

    I have an SM124 monitor that works fine, but the rear section of the plastic shell is broken in multiple places. If anyone has one of these that doesn't work but has a good rear shell section, I'd certainly be willing to take that piece off your hands before you toss the monitor. :)

     

    thanks!

    OK, so this really isn't "classic" stuff that I'm posting about, but I'm in need of a bunch of PC133 memory for some older machines I have. If anyone has any to spare (128MB or bigger is preferable), please drop me a line.

     

    thanks!

    I have 10 original Apple II game disks packed up in a hard floppy case and boxed to ship. Unfortunately, the person who I was about to send them to had to back out of the deal. If anyone is interested in getting ahold of these, please drop me a PM. I have the following:

     

    3.5" floppy

    - Bard's Tale 3

     

    5.25" floppy

    - Frogger

    Does anyone have any spare power supplies for the Atari XL/XE series computers? It seems every time I get a new machine I also have a power supply go south on me. If you happen to have an extra or two, please drop me a PM so we can work something out.

     

    thanks!

    Anyone have one of these? I'm looking for the most basic working system that I can find. I'm using it for parts so I don't need controllers, power supplies, or anything else but the console. Donations are also accepted as well and I'll pay for the shipping? :D

     

    Thanks!

     

    I have one on my tradelist. Works great, so it's too bad you want to tear it up, but that's your business. :) Anyway, take a look and let me know if you have a trade or cash offer. If you're parting it out anyway, I may remove and keep the extra plug I put in for the power supply...

    I need a few, 3-5 would be great. Can buy or trade. The eBay scalpers are charging crazy high shipping costs on these, so anything reasonable would be awesome. Email or shoot me a PM if you've got some spares sitting around :D

     

    See the "free stuff" section of my trade list. :) Pretty sure I have the Genny 2 type.

    64K should be enough for me since this machine will be dedicated to running cartridge games. The other machines I use are loaded up with bigger ram, internal MyIDEs with CF cards, etc. etc.

     

    I see, then you would not need more than 64k in most cases. Have you tried to have both OSb and XE rom on 2 different chips and switching between the 2 for your problem with 400/800 carts and XL/XE cart?

    something like this?

     

    That's another switch I don't want to have to flip. :) At any rate, I got it built with Omnimon, and so far nothing I've put in it has failed to run. So, I'm calling it the 600XLGS (GS for Game System). It now has 64K RAM, A/V output, Omnimon XL OS, and built-in Galaxian. I can't think of much else that would need doing for this purpose, so I'm also calling it "done".

    This compact machine should fit well on my game console rack. :)

     

    Then I assume you have done the composite video output.

     

    Or Metalguy's internal MyIDE. The OS version fits inside a 600xl

    post-7833-1158423932_thumb.jpg

     

     

    I too like the 600xl for its size. I have 4. 2 upgraded to 64k and I have 1 external 64k upgrade from Microbits. 1 with the composite mod. I just bought a PAL 600xl too. I did the ram upgrade, Metalguy did the composite. I probably could have done it, but I did not have all those parts. I think BEST has the full mod for only $12. You will lose the Channel 2-3 switch with that mod though. It should then look like the PAL 600xl ports.

     

    He is working on a 256k upgrade for someone, but he has been busy with the MIO boards. If you are interested, let him know. He might give it more priority.

     

    I have the parts for the A/V mod and will be installing them today (the one I got did come from Best, and it has a few more parts than the freenet mod). Also, I did a little more querying and found that Omnimon may be the best OS for me here. In my testing thus far, it has worked with both cartridge extremes and it of course will run the internal BASIC cartridge as well, so that'll most likely be the one.

     

    How do you like the external RAM upgrade? I also got my ram parts from Best and chose to go with the internal mod to keep it as low profile as possible. 64K should be enough for me since this machine will be dedicated to running cartridge games. The other machines I use are loaded up with bigger ram, internal MyIDEs with CF cards, etc. etc.

    I'd recommend the thing to do is to replace the ROM in the cart with a patched one where possible, drastic I know ;)

     

    Since most carts don't have eprom boards in them, that wouldn't seem like the easiest thing to do. Only thing I'm willing to modify is the machine itself, and it seems that the 800 OS with 64K memory is the ticket.

     

    I'm actually doing all this with a 600XL because it's the smallest of the bunch. I've upgraded the memory to 64K, swapped in the 800 OS, swapped in Galaxian for BASIC (in case I ever find an OS that will play everything AND support the built in cartridge rom), and I'm upgrading the video today. This compact machine should fit well on my game console rack. :)

    The AtariMax 32in1 OS is probably the best solution.

     

    Or, a mulitcart, then run "fixed" games from it.

     

    Most software that had issues was pretty easily fixed. In most cases it was just jumping to illegal entry points in the OS, or using memory locations which shouldn't be altered.

     

    I didn't think that there would be any games with problems on the 800, for any other reason than needing the extra memory.

     

    Thanks for the suggestions. I have the 32-in-1 in another machine (it's great), but I'm looking for doing as little as possible to move from one game to the next. Of course, the exception to that is I actually like to use the original carts as well. Not sure why - it's just my thing. :)

     

    This reply did remind me to do something I had meant to do already, and that was to try the XE games on my XL with the 32-in-1 booted in OS-B. Lo and behold, it ran everything I tried in it. :) If the image Steven uses for the 32-in-1 is modified to be a 16-bit binary, then I should be able to get that from him and stick it in my game machine.

     

    James

     

    Indeed! Thanks again for helping to knock my brain back into place. I pulled the OSB image from the 32-in-1, stuck it in the XL, and everything works just fine. This was actually the first thing I was going to try before I started messing with BOSS, and it's amazing how the easy things get away from you. The only thing that I can't do now is make use of the Galaxian image I put in place of built-in BASIC (since OSB doesn't know anything about built-in BASIC).

     

    There's another OS for the 32-in-1 listed as "800 compatible". I wonder if it recognized the built-in BASIC rom. Guess I'll just have to see...
