  1. Any Chance anyone has the most recent ANT as an ATR file so I can run this from an SDMAX ?
  2. I'm interested in the Alt label Raiders, and Target Fun. Do you have pictures.
  3. Hi, I'm in Chicago, and can install the U1MB. I've corrected one from an 800XL and installed one in a troublesome 1200XL and got it working faultlessly. I do mods on Atari's and other systems. If your interested, shoot me a PM.
  4. I'm planning on a 7pin Svideo Size jack that's through Hole. It's the same diameter as the RF jack. I can add Svideo, Composite, Ground, And Stereo out on it. I'm also building 2 custom cables for it. I'll be my own system I do this to. I was hoping to find a Sega rev 2 jack that was though hole, but I can't find any beyond PCB mount styles. It's a more common standard that would allow any assortment of cable purchases if another is ever needed, vs repairing a failed cable in the future. This project is only in the planning stages, so I don't have any examples to share.
  5. PM me. Let's chat about your setup and what you'd like done.
  6. I restore, repair and mod 2600 up to 1200XL's. I even build Gotek drives for STs.
  7. DONKEY KONG III for the 7800? Anyone ?

      I've thought about it several times.  I haven't yet started messing around with the 7800, though.

      I think it's a much needed title to add, especially if it supports the 7800XM. :)

       

  8. Crazy Climber reimagined for 7800 Please!! :)

      I would have liked to see it on the Colecovision.

      The original company that owned it, I believe sold it to another, and that company went defunct in 2014. I'm not sure if anyone even owns the rights to CC anymore? If they do, it would probably be in a Japanese holding company. Of course making it a little more work to sort out if it would be a problem to even make the game by name, or call it something else. Building Climber? Unstable Climbler? WTF is that man doing? Climber.. Well you get the idea. ;)

  9. I'm looking for a 1030 modem on the cheap, basically so I can do a win-modem mod to it. If it works, I'll save it's internals, and won't destroy it with holes.. This will be an invasive free mod.
  10. Hey all, I'm putting a query out to see if anyone has an interest in making XL BOSS, or a forward compatible version of OS B with PBI for the Ultimate 1 MB. I did various tests, and even confirmed with Jazzcat that PBI functions of XL Boss are not working for it, or non-existent. Now the rational for my query to make it PBI supported is this. I found that the game ENCOUNTER!, *Which has other revisions that work with the Base XL version on the Aug 2019 rev of the U1MB update works with other revs of the game. Sure, you'd think that would be the end of that knowing other copies work. But what if you ran into a game that was not? Or just needed to have that straight up backwards 800 compatibility, other than the OS B PAL or NTSC rev. For some reason, the XL Boss rev 2 works perfectly with loading up this un-patched version of Encounter! Now don't get distracted by me repeating this one game. I can live with the work around. What I'm looking for though it a community level update to XL Boss to use with the U1MB on a routine basis with PBI support. The original thread I found on XL BOSS is noted below. I've already had some discussions with Nezgar, and it does seem like a plausible idea to do. There's a few other features of XL Boss that are meaning full to use, and there's even many who've tried to use XL BOSS, but I can't find mention of quirks with PBI. NOTABLE TESTS RAN: Equipment: | Atari 800XL - U1MB | SDMAX - SIO - Gavin SIO board latest rev. | Side test with, same results as U1MB Boss Xl rev. Atari 800XL with OS rom replaced with patched HSIO and Boss XL with reverse Option only mod | Game: Encounter 3 versions ran against the default u1mb OS choices (excluding XEGS) - Either lead to black screen, start screen, but locks on starting the game. U1MB CHANGE: Replaced XEGS with Boss XL Rev 2. - Game runs as normal. --------------------------------------------------------------------------------------- Load Boss only, no cart, no SIO option, loading Sparta up. - Sucess OS works with Sparta seemingly normal. Load Boss with SideCart2 - Cart only mode and ATR mode - Unable to see it - Alternatively J.S.C. ran some inquiries for PBI fumction, and nothing indicated they we're found by the os. Keep in mind, this focus is not on the game, as much as it's an inquiry to make XL BOSS a possible alternative OS for the U1MB. Thanks for your input all!
  11. Good news, after replacing caps, the 2 multiplexer ICs that are recommended to be swapped out for new & re-flashing the SST 32pin eprom. Then scouring over the board with a scope. It looks like I've remedied the issue. My system is working perfectly, and in harmony with the Side2 Cart. I love this thing ! It gave me so much grief to start. But the all of the hard work paid off. Many thanks to all of those that have added viable suggestions to this post.
  12. Update. I've been trying for hours to correct some issues with the sparta dos hang on both U1MBs. I moved a setup to my 800XL for some base line testing. I get the exact same results, the in ablity to find the U1MB with the firmware update, and black screens on a regular basis. I've loaded Altira up, but nothing else works. It progressively failed on each one. The Side2 cart however has loaded sparta fine each time. So all of my cross comparisons lead to the noisey RST line causing what looked like a normal clean installation to fail and corrupt it enough that I could no longer do it again. Taking lead from Flashcat's guide, I'll be getting a MiniPro TL866CS and reflashing the roms. Meanwhile, I'll be waiting for the 1nf cap and the IC replacements to show up. I'll try it all again from the start with these patches persay and see where I end up.
  13. I've been reviewing and checking over things while waiting on parts. I'm determined to get this working 100%. I did manage to get my Side2 Cart flashed with some minor tweaks and used the SIO2SD to load up the software. I'm still without a proper SD card, I have another one on the way that's a dead match for the one Lotharek sells. Which I should have just simply purchased from him. Currently both of my U1MB boards are acting nearly the same way. So I'm hopeful that adding the 100nf cap and swapping to the 74LS138 corrects the very unpredictable behavior. Nobody likes looking at a screen that won't load the clock or OS. -_-
