  1. We have quite a few tech savy folks here, so excuse my OT, but this may be a question that others may find useful.  Are there any English language forums for using, rebuilding, etc. of batteries -- especially 18650 battery packs?  There are quite a few videos on YouTube that are helpful.  But I did not find any forums in a few searches online.  I have rebuilt a few laptop packs that worked (and didn't burn up!), but I'd be interested in getting a spot welder, etc to do the job right. Any ideas?


  2. I'm getting ready to upgrade a new NTSC 600XL.  I'm wondering about what to do with the video.  How does UAV compare to upconverted to HDMI?  I've used the PC All-in Wonder card with S-Video for many years, but I'd certainly consider a newer alternative.  As far as the UAV goes, are there any issues in installing one in a 600XL that is only fitted for RF output? I know I'll have to remove the RF modulator to put in the Video Jack. That's not a problem.


    I'm also wondering about putting in Antonia 4MB upgrade vs U1MB?  I know that the 65816 processor causes a few incompatibilities as opposed to having the 6502 in the U1MB.  Any (friendly) opinions on these?  ASAIK, both these require that a 16K machine must be upgraded to 64 MB -- is that correct?


    Edit:  I also wonder about RetroTINK -- is the picture size scalable?  That is always an advantage with the earlier ATI AIW cards.  I know the RetroTINK gets a lot of positive feedback.



  3. I've always wondered why Atari didn't use an off-the-shelf connector instead of spending a goodly amount (in those days) to create a custom plug/socket system?  Weren't there were DIN or other connectors that would have worked?  (It did for the ST, didn't it?)  Any thoughts or info on this?  Maybe in the whole scheme of the project this would have been "small potatoes?"

  4. What is the difference between MyCopyr 1.x and 2.x?  Where did these originally appear?  And last, is it MyCopier or MyCopyr (I've seen it listed both ways).


    I seem to remember seeing it in one of the U.S. Atari magazines, but there have been quite a few that have similar names so I no longer remember.  Maybe the one I saw was MyCopy (no "r").  Curious about the history of this.



  5. Copying a disk with one bad sector is no problem, but how about disks that have bad tracks or many bad sectors per track?  Can a stock 1050 (for example) deal with that without many, many retries?  Is there a sector copier that can just make one attempt and continue?  (I don't think so, but...) Of course, modified drives like Happy, Archiver, etc. easily do this. This problem rears its head when using patching programs like Chipmunk, The Black Patch, etc.

  6. It is definitely possible.


    Atarimax used to sell a 1Mb cart of MyDos (4.53 I think).  I can't find any images currently at the Atarimax forum (flash cartridge discussion).  I looked through my carts, but do not find my old MyDos cart.  Do you have a flash cart Studio to program the image?  If you have 8 Mb carts, the image won't work without serious changes.  I'll send you a PM with a couple of other suggestions.

    SDX and its SIO drivers is a separate question. SIO.SYS is slow and it has been known for ages. Worse, I am not sure if this is fully fixable, but the current betas (which some have) do contain a SIO.SYS driver which should be faster.


    As for IDE+, the thing I could do is to shorten the intervals the procedure is spending in setting up the consecutive phases of the transfer. I can already see under the emulator that if the data block is sent by the external device immediately after the 'C' acknowledge (at divisor 0), the receiver may have a problem with catching up. I will see what can be done, unfortunately the only means of testing this for me is Altirra.


    Is there an general explanation about why SIO.SYS is slow and may not be fixable?  Just curious.

    I rarely use anything faster than UltraSpeed on any device, but I realize that some folks want to go faster.

  8. Konrad, your procedure works great!  Thanks so much for explaining this. Your procedure will definitely become an addendum to my IDE+2 docs!  I would not have thought to load side B first, then side A and then rotate them.  Might I also add that the loading time is really, really fast! 



  9. OK, now it no longer goes to SDX.  But it still doesn't work (as best I can tell).  If I follow the docs, it tells me that the Side B ATR is mounted on D11.  It would appear that the SDFS file system must be D1. (?)   I will send you a PM. 

  10. Updated successfully to 1.7b.  Using a 320K 130XE. But the Load Executable doesn't seem to work at all now.


    - I highlight the same ATR in the SDFS partition (D2:)

    - I press OPTION + RETURN

    - It just goes back to SDX. 


    I am using 4.46 (still) in the IDE+2, but also tried turning off SDX in the interface and plugged in 4.49 in the SIDE2 cartridge.  I am using the docs for bios 1.7.  I am following the same steps that I did when flashed to 1.6.  It loads the first ATR perfectly (no return to SDX).

  11. OK, back on it...  (It was a long errand) ;-) 


    The procedure works great for Side A (the bootable side), using L Load Executable.  But after the program tells me to "Flip the disk and hit RETURN," I can find no way to mount/access Side B.  Since it is a data disk side, it just has to be there and then the program goes back to the correct position in the already loaded program. 


    Reading further into the manual, it looks like I need to update the firmware to 1.7? (Currently at 1.6 -- there are several 1.7 versions, aren't there?)  Which one should I choose, if this is likely the issue?  BTW, it boots really fast!  I believe it at least as fast as using the Black Box. 

  12. "Format" -- I had forgotten about "Build Directory"  Got it, now.


    Another question... Does the SDFS partition need to be bootable?  I suspect not, but still good to ask you. On the CF card I'm using, the main bootable partition is a MyDos partition, and D2: is SDFS. 


    Where does the ATR need to be located in order to get copied? If it is mounted (say in APE), then the header is invisible, isn't it?  So I'm presuming that the ATR can't be already mounted.  If I use COPY D5:*.ATR, D2:, then I get File Not Found.  In your example where is GAME?.ATR located?  Sorry about the basic questions, but I use SDX maybe once a year.

  13. Have not gotten that done yet. Maybe I'll get it done today?  I was hung up on the SDX formatter, but watched a Nir Dary video that helped.  But since you've asked, when the ATRs are copied to the partition, is it just a regular file copy? That means that the ATR  header is not copied.

  14. About the 800 not closing... BITD, I used a corn dog stick. Perfect thickness!


    Now a question about the screen shots.  I noticed that the SAGA "Adventureland" is shown, and appears twice on each screen. Were these versions patched so that images didn't need swapping (maybe an XEX file?) or is there a non-destructive way to load the second side?
