  • To answer your questions, I'd have to read the Wiki documentation to you. Since we're not face to face where I can do that, I'd have to copy&paste the documentation here. Please understand that I'm taking the short route and point you to the documentation. It has worked for hundreds of other customers.

  • Nevermind.

    Im not a technical person in matter of screen resolutions and how it works :)

    My strength is network in terms of user and group policies on modern computers.


    Seems like I now have 1024x768 70hz without icon flickering but have no clue how I managed to get it (Pure luck 8))

  • So I got a guide from EAB where I am bit stock atm. http://eab.abime.net/showthrea…hlight=indivision+aga+mk3


    Under creation of custom vga mode he write :


    - You will notice the frequency values will change by doing this. Use the Pixel clock slider until the Vertical Frequency changes back to 60Hz again, or closest possible.


    In that specific screen I don't have a Pixel Clock slider only F. Porch, Sync Len and B. Porch

    Which of those does he refer to ?


    My Samsung Suncmaster P2450 has in the Standard Signal Mode Tabel a Pixel Clock

    VESA, 1280 X 1024 63.981 60.020 108.000 +/+
    VESA, 1440 x 900 55.935 59.887 106.500 -/+
    VESA, 1600 x 1200 75.000 60.000 162.000 +/+
    VESA, 1680 x 1050 65.290 59.954 146.250 -/+
    VESA, 1920 x 1080 67.500 60.000 148.500 +/+


    Can't figure that one out


    Any suggestions ?

  • "that specific screen" is rather ehh unspecific? I guess you are looking at a window with the label "Select and Edit VGA mode"?

    There is only one slider on there. I think the others like F porch and sync are are referred to as "spin controls" at least that is what they are called in windows. Please look again the pixel clock slider is at the top of this window above all the other controls you named.

  • Still waiting for anyone to report back if the latest firmware fixes the audio problems. We can't possibly run all test cases for a feature that was never advertised, but now that we've spent time (=money) on it, it would be nice to hear back if we can start advertising it. After all, the price of Indivision AGA MK3 needs to go up next week (higher VAT rate, higher salaries by law in Germany).

  • I tested the new firmware 1.8 with some games like Turrican 1,2,3, Apydia, Rick Dangerous 1 and 2 WHDLoad versions and I get background music and sound effects. I think the audio problems are solved.


    Thank you Jens.

  • Hello there!


    This is my first post. I read through many pages of this thread, in search of answers as to why my Amiga constantly crashes after installing the Indi3. I have to power-cycle it multiple times, before I can get to the Workbench screen. Once I've reached the Workbench desktop, I can run the Enigma demo for a few minutes until the screen turns black. At that point it sometimes gives me a "Software Failure" screen or the screen just stays black indefinitely. Removing E123C and E125C have made the crashes worse and now, when the Amiga freezes during startup, it's sometimes showing a completely blue or a completely yellow screen instead of just a black screen.


    This may be a stupid question, but could my original 29 year old PSU be the issue? It's a "Power Supply A 300" with part number 391029-03.


    Hardware:

    Amiga 1200 rev. 1D.4

    Kickstart 3.1 ROM(s)

    Indivision ACA1221ec (default settings)

    Indivision AGA Mk3 (running latest firmware from the 1.9 disk)

    IDE-CF card interface (running a 4GB CF card) - this is of course moved away from the top of the Indie3, after replacing the EM shield


    Mods done (in the order they were done):

    1K resistor to fix the PCMCIA socket

    EM shield HDD tray cut out, to make room for the Indi3.

    E123C and E125C removed (attached before/after pictures)


    If I've left anything out, please tell me and I'll provide information as I'm able. It's getting late here (23:46 at the time of writing), so I'll most likely not reply before some time tomorrow.

    That may be the most obvious cause, yes, but you may also double-chek if your CF card adapter blocks air to circulate above the flicker fixer. Placing it right on top of the unit might give it more heat than it likes.

    Hello Jens. Thank you for your reply. I am already moving the CF card away from the Indi3, when assembling the Amiga again. I just fold it to the left. I started doing that, when troubleshooting these crashes, but it's made no difference.


    Is there any way to find out definitively, if the PSU is the cause? It's quite a high price to pay, if that's not the issue. I will of course buy the PSU off of you, if I decide to actually get one. (I read about the terrible PSUs bought elsewhere by other users on here.)


    I didn't clean the pins on the chip, I put the Indi3 on. Should I do that? I think it actually needs a good clean in general...


    I fix computers for a living - and have done so for decades here in Denmark - so I know my way around them. I had Commodore 64, back in the 80s but went straight for the PC in the early 90s and only got my first Amiga in the very early 2000s. It was an Amiga 600HD, which I quickly traded for this Amiga 1200.


    Sorry, I'll stop rambling. I just don't know anyone in real life, who's old/nerdy enough to have messed with the Amigas :x

  • Is there any way to find out definitively, if the PSU is the cause? It's quite a high price to pay, if that's not the issue.

    You do have a right of revocation: If you don't like the unit, you can always send it back within 14 days. That's EU law.

    It was more me wanting to avoid the hazzle of sending it back. Sending packages here in Denmark isn't cheap.


    But I'll order one, thank you :-)

  • For what it's worth I had a similar setup as you ShamblerDK albeit the ACA1233n55 and the original A1200 non-hd PSU.

    My CF adapter covered the Indivision and created too much heat. I changed to an angled IDE2CF adapter which improved the situation but machine was still unstable. I bought the CA-PSU and my issues where gone and the machine has been stable since.
