What is the better Paula sound hack ?

do you use fblit or no ?

hi jens what do we need to do to fix the gfx curruption im using a 1d4 mob0

with fan on indy and a heatsync on alice i still get it if i go over 16col on highgfx:super high res laced

thanks john

Well i just made a test on another board that i have, it's exactly the same as my 1200 it's a 1D4 NTSC board and for my surprise the icons started to get corrupted but when i change it back to my 1200 the problem disapear so i guess that this is a random problem, not caused by any specific board revision but like Jens said it's a chipset problem.

Does anyone made the fix told here by Jens? Both on Indi and on the board?
It would be nice to have pictures.

darksun9210 · 29 May 2012, 10:14

on a related note, the bvision and indivision mk2 boards kinda fit in the same space, just can't fit the dvi ribbon cable onto the end of the indivision as there isn't enough space.

anyone got any ideas?

cheers,

cheers,

You can solder cables there or you can solder pins to a pcb board (sanded a little to give more pressure to the connection) up and down, that you "plug" to the Indi. Just an idea.

Could someone tell me where to put the 1K resistor on the cck signal on the motherboard ?? I can do it but as I do not know what and where is the cck line ..... And i do not want to do soldering on the mk2, for warranty and if a day I want to sell it...
Thanks

Best place on the A1200 motherboard is the top left corner of the unused FPU socket. There's a via with the CCK signal and a via with VCC very close together. You should ideally use a resistor of 1206 size, so the distance is bridged easier, and it should also be easier to solder.

Other places would be on Paula or on the underside of the board on E127R, but this one allows the mod without having to remove the board from it's shield.

I've marked the place for you to see better.

I used Jens picture

for comparing

I haven't done any conclusion. I just try to understand wich fix is adapted for my case. It is clear that it was not my intention to use fblit to patch the "issue".

Here is a video of the issue : [ Show youtube player ]
The Amiga is cold. It is the 1st boot of the day.
Then when I launch Fblit, I don't have any glitches anymore

Now I have soldered a 1K resistor like in the pic above, I have more glitches than before !

Ratte,
removing protective comonents is NOT RECOMMENDED. Use of a cable without the clamping diodes might lead to damage of the DVI encoder chip. Your cable is not complete without the clamping diodes.

Gibs,
Your video title is misleading. What you see is a Blitter glitch, not an Indivision AGA MK2 glitch. Just like the old version of Indivision AGA, this new one takes the AGA chipset to it's limits, and on some, you see that timing errors of the chipset have not been corrected properly on all boards. If you remove Indivision AGA MK2 and display that video mode on a monitor that can handle these frequencies, you will see that the glitches are still there.

You may have to do more tweaks to your mainboard. This looks like a wrong blitter call, where your accelerator's timing does not match the mainboard's timing. I'm assuming that this is the cause for the Blitter doing funny things in your computer.

Your photo shows two arrows and "0.5k" - if that means that the resistance between these spots is 0.5k, then the falling edge of the CCK signal gets too flat, probably making matters worse. Check E127R (might have to be replaced with a ferrite) and E127C (might have to be removed), but also the usual suspects E123C and E125C that may have to be removed for proper accelerator operation.

Jens

gibs · 30 May 2012, 15:00

Thanks Jens.
Ok I understood. This video was just to show the issue.
I will modify the title & the content if I decide to keep it if it can help the community.

Yes I have 0,5Kohms at these spots.
I will check E127R and E127C ASAP.

BTW what kind of ferrite do I need to put ?
Thanks

Hello,

A little video in highgfx 1024*768 , 256 colors would be welcome please

.

Thanks.

gibs · 30 May 2012, 19:50

Mine is 1024x768

attila06 · 30 May 2012, 19:58

Gibs,

Very nice backdrop, how many colors ?

your workbench is very reactive.

Hi guys!

I receive my Indivision AGA Mk-2 (A4000D version). I did make a little test with my PC monitor and the result was this:

What you thinking about this?

Thank you!
Best Regards!

gibs · 30 May 2012, 20:57

I have removed E123R & E123C
I have removed E127C

ATM I let E127R (because I don't know wich ferrite to put instead)

The result is worst

Attila06, my backdrop is in 16 colours (and it's one of my shot)
