  1. what version is that?

    crashing should never occur.

    try RI see if the box appears then DTR and see if the check box appears... (just to see if it's in there somewhere)

    I had mine set at 300 so 250 sounds about right.

    DTR control is normally used to switch devices between SIO 2 PC computer vs SIO 2 PC drive modes

    If this is the latest version with the build crashing, you will need to contact JoSch on discord because that's bad and I haven't seen that since AspeQT days.

    I am using Windows as of late so indicate to the team on discord all the normal information/ Linux build ver etc.

  2. Tools

    Options

    Serial port backend

    make sure the correct flow control handshake is selected for your specific cable

    a check box exists for edge timing (normal or falling edge) slight

    at the bottom is further timing in uS for timeouts etc.

     

    there are further adjustments for SIO divisor rates as well, greyed out until boxes are ticked.

    these appear and disappear based on selections already made that pertain to the functions.

  3. So I should have said traffic cops, someone is taking too long getting the message in or out on the radio/walkie talkie and the stop signs on either end of the single lane are not being turned in sync. So you will have a head on or no cars at all for a bit. Unless there is a glitch in the instruction being executed that is. Anyway faster saves might have been helpful keeping waiting data from occurring or timing out.

  4. No, using a ramdisk on a MIO or in the Atari side since the data is going to the device residing on the Atari Side, Remember the 1090 was to have a hard disk card as well. So I'd figure a quick test would be to see that it's flow control and buffer perhaps within the I/O window.

    The faster save at he higher rate might have meant less buffer overflow or less I'm not ready/I am ready toggles.

    Saving to a fast SD storage etc.

  5. Defective Design and implementation, I'd say all these need to be returned to the manufacturer. That's the fix, there is no other unless you make your own guts and use a center pilot/pivot hole and pin.

  6. Sparta DOS, SDX, MyDOS, DOS XE, OSS A+, DOS XL, DOS 2.5, LITE DOS, xBIOS, DOS 4 (Antic), DOS 4.x

     

    we use them all, but the first half or so on the list is used most by the world.

     

    I could have kept going because we use them all for the most part. Each has their uses.

  7. that also depends on the disk set up.

    in any event, almost everything was configurable to a degree on these old machines, so when you say there was no standard for this or that, well that's true for almost anything, but there were ranges of addresses settable via dip switches and jumpers that sort of became 'settled' over time.

     

    as to memory, 256k and 1 MG boards were commonly in use, and easily purchased both static and dynamic from multiple sources here in the states as well as a number of video cards and specialty cards. Like every other machine, how you decided to implement things were up to you but there were still ranges to stay within if you wanted everything to work.

    endless sites like the above all with different cards etc to peruse for the best choices to make a multi-function card or remake of a great old card

     

    for a chuckle, everyone has the most...

  8. Good stuff,

    If people were not such butt heads about things, you're fun would not be diminished and better things would happen.

     

    I send Heaven/TQA Greetinx, and chaplin Fu*kinx.

     

    Thank you for sharing your happiness with us, I was pleasantly surprised.
