    So, I re-spun the 65xxT board to have a jumper option for pins 34 and 36 (R/W) and added pin 35 (/HLT).  So, next month I will start doing some testing with an Atari 400 or 800 to see if the halt line works correctly.

    I am thinking in the $69 range... depending on quantities, maybe less.

     

     

    Great news, Jim!!  Looking forward to the final product!!

    I really appreciate the offer; however, I will not accept anything under false pretences, so if absolute commitment to creating a replacement menu in a timely manner is a condition of donating the device, please hold off until I can confirm that the undertaking is even plausible. Let me read up on the documentation so I can get an idea of what's involved. If I can re-use UI code from elsewhere, maybe it won't be that hard. :)

     

    Slghtly off-topic, but directly related to your comment above:

     

    Another group that could really use your creative talents in the BIOS GUI department is the EclaireXL Project (all variants).  Their menu is fully functional, but unfortunately not very attractive.  What can I say -- you spoil us Jon in this area with your excellent BIOS GUIs for U1MB/Incognito/SIDE2.

     

    I'm not affiliated with the EclaireXL Project in any way, shape, or form.  This is simply one man's opinion.  I just wanted to make you aware of another project that could use your talents.  Please consider it a complement that when I see their menu system, the first thing I think of is how much better their (EclaireXL users) experience would be if they could use your style of BIOS GUI on their machine.

     

    However, I do realize that you are just one man, and you can't do it all.

     

    Thank you so much for all that you have done -- we all appreciate it more than we can adequately express.

    The creator of Antix (Level42 on this forum) had some personal issues the last few months. The Antix has not been produced yet, but I still have the list of everyone who has filled out the interest form on the website. I hope his personal issues will be solved soon, so we can produce the Antix.

     

    If the Antix will not be produced somehow, I will add my stack of brand new PAL & NTSC Antics to my webshop. 

    Thank you for the update.  I also hope his personal issues will be solved soon.  I stand ready to make a purchase when everything is ready to go. If you do wind up putting those new ANTIC chips on your website, please let us know.  I'm sure several of us would be interested in purchasing some chips for use in various other hardware projects (1088XEL, 1088XLD, etc.).

    Did I not release a player which works with the MYIDE II? Perhaps I should.

     

    I for one, would appreciate it. I have an 800XL, 1200XL (for others) and 800 already in line for rebuilds and upgrades before I even get to my second 1200XL with U1MB & SiDE 2, or probably a couple of years in reality.

     

    I would appreciate it, too.  +1 to Gunstar's request, please.

    I know we live in the age of 7, 14, and even up to 20 Mhz 65816 upgrades for our trusty A8, but has anyone ever tried overclocking the stock 6502c (Sally)?

    It's been speculated that the stock CPU might be rated for up to 3 Mhz which isn't that far away from the primary oscillator speed (NTSC: 3.58 Mhz, PAL: 3.55 Mhz). Understandably trying to run the CPU above its specification is undoubtedly going to create considerably more heat, but perhaps with a good heat sink and a small fan that can be tolerated. If this could work, it would be a fairly simple way to double the clock speed and yield some acceleration, doing nothing more than swapping the existing CPU clock input for the one feeding the GTIA.

     

    So back to my question... has anyone attempted this?

     

     

    Respectfully request you contact Jim Drew of CBMStuff.com (http://www.cbmstuff.com).  He recently posted on the Apple II Enthusiasts Group on Facebook about a 6502 Accelerator board he is working on that could work not only in the Commodore 8-bit computers, but also the 8-bit Apple II and Atari computers.  Here is the Facebook link:

     

     

    Maybe you and he can share information and/or ideas about 6502 Acceleration, and how best to implement it in (in our case) in our beloved Atari computers?

    Like everything in life, it is what people make of it. I run six different tech and retro groups full of great people posting fun and interesting stuff. I participate actively or follow several more. YMMV. 
     

    What are the other tech and retro groups you run?  I enjoy reading your comments (and appreciate you sharing your renewed Atari knowledge) and would love to know where else I can get more tech and retro knowledge from other great people in the community.

    *** UPDATE ***:

     

    Thank you all for your suggestions and comments. They are greatly appreciated!!

     

     

    Thread here:

     

    http://atariage.com/forums/topic/254160-antonia-4mb-operational-questions/

     

    Confirmed issue, but work on a fix appears to tail off.

     

     

    Thank you for pointing this thread out, flashjazzcat. It was a very informative read, and I see what you mean by the fix appearing to tail off, since the last post was in late February 2017. Hopefully now with a little prompting from me, we might see a solution here in 2019.

     

     

    the 1200xl has cartridge port access issues - some carts dont go in easily. could this be the problem?

    also, can you easily "de-antonia" the 1200xl? if so, it would be worth testing the MYIDE II cart this way to narrow down the cause of the fault

     

     

    Great suggestion. I've done a new round of testing to narrow down / confirm the suspected cause of the problem.

    I forgot to mention that I use Dropcheck's 1200XL Cart Extender Board with a 3D printed case made by Corei64. This combination looks and works GREAT, so I have no problem plugging in any Atari 8-Bit designed cartridge into my 1200XL.

     

    I "De-Antonia'd" the 1200XL (restored back to stock CPU, MMU, Rev 10 OS), but left the Sophia DVI in place. In this configuration, the MyIDE-II cartridge works perfectly!! I was able to load and run programs from the Main Workbook Menu Screen, as well as be able to run programs via the FAT32 Loader option. Both of my MyIDE-II cartridges (one with stock configuration, one with updated MyBIOS-V04) work similarly well. No issues.

     

    I also decided to test my other multi-carts as well, so I can tell you that these work without issue as well in the Stock + Sophia DVI configuration: TheCart!, Ultimate Cart, UNO Cart, AVGCart, and SIDE2.

     

    I then reinstalled Antonia, and selected one of the default XL OS with Atari Rev. C BASIC options (the Antonia comes with all 8 slots filled with Stock XL OS and Atari Rev. C BASIC). I then tested all of my multi-carts again. All of my multi-carts that I listed above work without issue in the Antonia + Sophia DVI configuration EXCEPT for the MyIDE-II carts. The MyIDE-II carts produce the same results that I listed in Message #1 above.

     

     

    The reason of the problem has just been found, so the solution should appear soon.

     

     

    Simius's statement above concurs with two private e-mails I received from Mr. Tucker of AtariMAX and Sijmen (Mr-Atari). Both mentioned phi2 signal abnormalities that are produced by the Antonia upgrade as the source cause of the incompatibility with the MyIDE-II cartridge. I'm sure that Simius's upcoming fix will include addressing these phi2 signal abnormalities.

     

    My Antonia board is a Rev. C with the latest firmware as of April 2019 when I purchased it (which, by the way, is there a way to tell exactly what version of the firmware I'm running, without having to hook up a USB Blaster and running the Altera Quartus software?), so I don't know if the upcoming fix will involve just a firmware upgrade to the Rev. C board, a new Rev. D board with existing firmware, or a new Rev. D board with new firmware. Regardless, I look forward to the fix, in whatever final form it takes.
