#4273274 MyIDE II not working on NTSC 1200XL with Antonia 4MB

Posted by irich2 on Fri May 10, 2019 5:06 PM

*** UPDATE ***:

 

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

 

 

Thread here:

 

http://atariage.com/...onal-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.

#4269081 Best system to put a Ultimate 1 MB into?

Posted by irich2 on Thu May 2, 2019 4:16 PM

 

You should see some of Jon's videos - he can get an AMAZING amount of stuff into a machine! 

 

 

I agree!!  Jon does some truly amazing work in installing new upgrades into our old hardware!  Be sure to see the videos he referenced in Message #18 above for U1MB with Adaptus Adapter install.  His YouTube Channel with his amazing Atari 8-Bit Installation videos can be found here:

#4268693 Disassembled an 800XL just now - not elegant?

Posted by irich2 on Thu May 2, 2019 2:48 AM

Yes I mostly agree the 1200XL vs a mylar SCCO 800XL seems to in some ways be a big step backwards as you noted.  The mech keyboard 800XL's have a more quality feel than the mylars.  They are physically lighter, too, which eliminates the "I'm holding a lead brick" feeling the very common SCCO 800XL's have. The joystick ports are better positioned. The computer runs much cooler and is 5v dc. The OS is updated and much more compatible. The 800XL motherboard is very well optimized, yes.  The problem with the 1200XL wasn't cheapening it out, imo. It was the super high price in '83. The motherboard is chock full of components. Not as crowded as an Amiga 3000 mobo however. ;)   

 

Going from an 800XL to a 1200XL, the impressive size and beautiful shiny keycaps is great. However the function keys along the top are more inconvenient and knowing of a cart is or is not installed is a thing.

 

The 1200XL can't run Crysis. The 800XL can.   :grin:

 

Try installing a U1MB in a 1200XL then in a socketed 800XL.  Overall though, to me it seems a matter of taste. I've been using the 800XL's much more than my one 1200XL. I'd love to have another 1200 and have been looking to buy one.

 

 

You can buy another 1200XL here:

A socketed 800XL didn't even need any soldering if Adaptus is used (hardware guys correct me if I am wrong).

 

 

You're not wrong -- here's how its done:

There are also port extenders for the 1200xl to bring the cartridge outside.

I can vouch for the extender board above -- it works great and is SIDE2 Cartridge friendly.  You can also get a 3D printed case for it here:

#4263796 U1MB Install Without Soldering

Posted by irich2 on Wed Apr 24, 2019 12:29 AM

If all of the chips on my Atari 800XL are socketed, it would seem like some sort of socket adapter cound be created to go bwtween the CPU and the existing socket that would have the 4 wires that the U1MB needs.

 

Wouldn't that make the installation solderless?

 

I don't suppose anyone has made one of these?

 

 

I installed an U1MB upgrade in an 800XL solderlessly using the Rapidus Adaptus Adapter for the 800XL this past weekend and I can tell you that it is possible and definitely does work.  (Tip of the hat to Flashjazzcat and his awesome Atari 8-bit repair videos on YouTube for articulating this idea during one of his U1MB install videos -- Thank You!!).  If you haven't ordered your U1MB yet, make sure you request Lotharek to include the Adapter (it's actually 2 PCBs with a connecting ribbon cable) and the 4-pin cable you'll need to connect the Adapter to the U1MB.  The following video from Lotharek's site demonstrates how to do the install with the Adaptus Adapter for the 800XL:

 

ATARI 800XL Rapidus and Ultimate installation

 

This is the video I followed to install my U1MB in an 800XL.

After a long break, I finally managed recording the next 3 parts all dealing with the Display List: Basics, Memory Mapping and Soft Scrolling.

 

 

 

 

 

JAC,

 

These videos are fantastic!!  Thank you very much!!  I know its been over two years now, but is it possible that you will continue your video series from here?  I'm sure I'm not the only one who would **Love** it if you would make more programming videos!  **Please** consider it!

 

Thank You!!




#4081415 SDrive-MAX ATX support

Posted by irich2 on Sat Jul 28, 2018 9:53 PM

For those that are hesitant (like myself) in cutting an existing good SIO cable, Lotharek's Half (1/2) SIO cable looks to be a viable option.   It is a 10" cable for about $8 - $9 US plus shipping. 

 

https://www.lotharek...tail.php?id=174

 

Lotharek's Half (1/2) SIO cable connects the following wires to the end of the cable connection: DATA IN (pin 3), DATA OUT (pin 5), COMMAND (pin 7), GROUND (pin 4), and +5VDC (pin 10).  Perfect for connection to an SDrive-MAX.
