    Here's a case for the original 2+3 button versions if anyone is interested:

     

    https://www.ebay.com/itm/Case-for-Atari-SIO2SD-2-3-button-rear-SD-version/172862827191?hash=item283f6d6ab7:g:9FkAAOSwRFdZuDPA

     

    $25 + modest shipping, for a 3D printed case. I'll post about my results when I get the one I just ordered. I asked for what I thought were the critical dimensions of the case, and a few were off by .5 - 1 mm, but everything looked like it would fit.

    Thanks for the link Larry. I ordered one also. the fit is fairly good but I don't like the cord exiting the rear of the enclosure. The buttons are very handy and easy to use.

     

    I usually only populate D1 and D2 because I run it with my Ultimate upgraded Atari.

    @Larry asked?

    What is that chip on yours? I've seen pictures of several like yours.

     

    My 20 pin chip IC is 74HC245. Originally with 74LS245 but problems with it and seller suggested I put in the 74HC245 because it is a faster chip.

    I always tried upgrading with button selection except for when I flashed to get the correct fuse setting....BROWN OUT failures.

    This SIO225.XEX mostly works, but not quite correctly. Looks to have been written for PAL, so not all of the screen lines are visible. And puts spurious characters on the screen. But it actually is functional. Does anyone know what these were written in? I would think assembler, but I noticed that one of the 2.5 versions (Mad Team, IIRC) says "rewritten in assembler." That seems to imply that the original was something other than assembler. So if it is compiled, it might be fixable by me -- maybe.

     

    I will look on the internet about reprogramming the Atmega. Has anyone done it or can add anything about the process with the SIO2SD? And is the "....all.bin" file used for the complete program? I have a programmer that will do the Atmega32, so if that "...all.bin" file is used, I should be able to reprogram it.

    I don't see this with my SIO2SD and 800XL. Mostly clean screen and I see all the viewable.

    My Sio2sd and the small thing to the side is a avrusb500 flasher for atmega32.

    Yes my old one is by Pigula? I upgraded to version 2.5 so I could get 8 SIO drives. Never was able to upgrade to any of the version 3.x Flashing never took. Seems like I have had it for 8 or 9 years. I quit using it after I got the Sdrive NUXX and the mini SIO2SD By Panos.

     

    I will post a picture tomorrow. Hopefully.

    Good to see I'm not the only one. I really like the Q, so I'll probably end up powering the SIO2SD separately.

     

    Has anyone else here used a separate +5V line to the SIO2SD?

     

    -Larry

    Larry,

     

    If you have not got 8 drives to show up with your SIO2SD, can you try this file to see what it does for you..

     

    sio225.xex

     

    Good luck I get 8 drives with this file..

    I have scanned through the DEVICE tree and have not found a stereo pokey item so that my Ultimate one Bios can be activated . And the AUDIO tree selecting Stereo does not activate it either.

    My real hardware 800XL with u-switch actives okay, but my 130XE with a stacked pokey chip plays stereo even though the Bios is greyed out not seeing this older style up grade. [ Is there a wire I could add to the mix to have the Ultimate sense this old upgrade. ]

    Most of the knowledge base can be found at http://seriouscomputerist.atariverse.com/pages/language/language.basic.htm#

     

    Turbo Basic and Basic XL/XE can except all of the Atari Basic syntax, but Atari Basic can not except any of the added improvements of TBXL or BASIC XL/XE.

    Atari basic can be compiled with MMG basic compiler or ABC datasoft compiler. Turbobasic also has a linker and runtime to combine source code to self loading file (com, or xex, or ANY extension you want to use.

    The MyBios variants don't use Check Sum system so these two bytes could be you own choice ---beta 16= 6001 as first two bytes.

    Your #2 is what I have as #1 and #4 but my OS signature is different than yours.

    My #3 is Rev2 with math pack are different OS signature than yours.

     

    My 65816 OS is C101 I did modify it to hold my Favorite font..
