EDIT: I have also contacted Mr. Tucker of AtariMAX for his advice on this matter (awaiting reply).

I have contacted Mr-Atari directly (awaiting reply), but I thought in the meantime I would also tap into the collective wisdom and experience of the forum for assistance. Here is my situation: I have two MyIDE II cartridges (both were purchased in April 2019), one with the original workbook and MyBIOS software that Mr. Tucker ships with, and one that has been updated to Mr-Atari's latest MyBIOS-V04. Both work great with my NTSC 800XL with U1MB installed. I also have two SIDE2 cartridges, both updated with flashjazzcat’s 2018 firmware, and they both work great on my NTSC 800XL U1MB AND my NTSC 1200XL with Antonia 4MB installed (Antonia 4MB Upgrade also purchased in April 2019). Unfortunately, neither MyIDE II cartridge works with my NTSC 1200XL Antonia 4MB. My 1200XL motherboard is DA 213 Rev. A. It has had its composite video cleaned up and +5V restored to the SIO port. All 1200XL IC Chips remain installed with my Antonia 4MB (in other words, only the 6502 CPU and MMU IC Chips were removed to install the Antonia 4MB). I also have Sophia DVI (NTSC 1280x1024) upgrades installed in both my NTSC 800XL U1MB and NTSC 1200XL Antonia 4MB. The results listed below were the same with composite and Sophia DVI video (the Sophia DVI video just looks much sharper and clearer). Here are the combinations I’ve tried: OPTIONS RESULTS Antonia 4MB Stock MyIDE II Upgraded My IDE II (MyBIOS-V04) RAMBO 1MB, Stock XL OS, Rev C BASIC No screen (Dark) Lit screen (Scrambled Title Screen) 800XL 64K, Stock XL OS, Rev C BASIC No screen (Dark) Lit screen (Scrambled Title Screen) 130XE 128K, Stock XL OS, Rev C BASIC No screen (Dark) Lit screen (Scrambled Title Screen) RAMBO 1MB, My-BIOS-ROM-FMP (V04), Rev C BASIC Lit screen (Jumbled Colors/Characters) Lit screen (Scrambled Title Screen) I've read in the AtariMAX forums and here in the AtariAge Forums that there were issues with Antonia and MyIDE II compatibility, and that Mr-Atari was working on a solution, but I never saw any resolution or solution offered for a NTSC 1200XL with an Antonia 4MB (unless I missed that memo somewhere???). Does anyone have a NTSC 1200XL with an Antonia 4MB that they have used successfully with a MyIDE II cartridge? If so, what and how did you do it? If not, is it that these two pieces of hardware are simply incompatible with each other and therefore simply will not work together? I don’t know what else to try. Any and all suggestions for resolution (whether compatibility is possible or not, I just want to know for sure one way or the other) are welcome. Thank you all for your assistance and feedback. Have a great day!! irich2

I love the Atari Fonts!! Great choice Kyle22!!

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: https://www.youtube.com/channel/UC4nx-i-2K34RDHyDn06i7Ng

You can buy another 1200XL here: https://www.eightbitfix.com/for-sale/8-bit-hardware/

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

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: https://corei64.com/shop/index.php?route=product/product&path=62_87&product_id=186 https://corei64.com/shop/index.php?route=product/product&path=62_87&product_id=187

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.

This video should help shed some light on the subject:

Agreed!! Thank you SO MUCH, Bill!!

Nir Dary of The Modern Atari 8Bit Computer made a video a couple of years ago on how to upgrade the SIDE2 cartridge:

Check out this link for a partial answer: https://ultimate64.com and this link: https://www.cbmstuff.com/index.htm I'm sure others will chime in soon with other links they're aware of.

Happy Belated Birthday, Gury!!

Please add me to the list. I'll take one with an adapter for an 800XL. Thank you, Sven!! This is awesome!!

Here's a link for a 1/2 SIO Cable on Lotharek's website: https://lotharek.pl/productdetail.php?id=128

What about hooking up to an OSSC Scan Doubler first, then to the Dell Monitor? Has anyone tried that? It *seems* like that combination would work. For example: RGB Video Connection on Amiga Computer -> Amiga RGB to SCART Cable -> SCART Input Connection on OSSC -> HDMI Output Connection on OSSC -> HDMI to DVI Cable -> DVI Connection on Dell 2007FP Monitor. I've successfully used a similar combination substituting "SCART to HDMI Converter" for "OSSC".

Also interested in a set when available, please!

Yes. PM tmp for current pricing and availability.

Received answer from tmp. Ordered and paid for AVG Cart. Highly recommend contacting tmp if you want an AVG Cart while there is stock available.

PM sent to tmp requesting availability of AVG Cart.

I just checked out your webpage with the example programs. Thank you for posting those examples! I hope that you will continue to add to the list as you come across more Pascal programs. I remember learning UCSD Pascal on an Apple II back in the day -- it is nice to see Pascal programs running on an Atari 8-bit also.

May you all have a very Merry Christmas!!

Thanks, Mclaneinc! I will wait for the updated torrent as you suggest.
