Indivision aga 1200

[kickstart]

After make all fixes to my a1200 1D4 motherboard, 1024x768 still gliching, sand the indivision connector its enought important for it?

Whats the last estable update for indivision? Any new nice resolutions for indivision? Maybe too much questions but im lost with the indivision at this times.

Thank you!

My indivision was having the same problem.I sold it on ebay as is with full disclosure of the issues I had. The buyer desoldered the esiting Indivision socket and resoldered a newer socket and that fixed the problem. He had experience with surface mounted IC's and desoldering so it was easyfor him. I hope they fix this in the next batch.

Using a bench grinding wheel, can't you just "grind" or trim that socket down to make a better connection? I remember reading where people have done this with great success. You grind down the socket until you just begin to get to the pins... BE CAREFUL not to overdo it!   :laughing:

[Crom00]

I over dit it....why should I have to take a $140 thingy that's supposed to fix the flicker to a grinder...?

I thought Germans made good stuff.

Totally my falult I wound up bending a pin, I placed a wire over the bent pin and that actually made it work but the display would still dsiplay some strange behavior now and then. Enough to sell it as is.

iv said this in another thread,the only *true* fix is to change the chip on the motherboard or the socket on the Indivision this is what iv done.

you can sand down the connector and it will work for some time, but after a while it stops working,i think this is down to small movment on the motherboard around the chip/socket when the A1200 is move or subjected to vibration.

"Colours of RGB $FFFFFF can produce problems with the built-in EMC noise suppression circuits, leading to colour flickering and, after a while, crashes."

It's possible your problem isn't with the Indivision, but with your colour palette. Try this patch and see if it helps: http://aminet.net/package/util/misc/BitmapShades

@Cammy

My palette is the original of os3.1

If the problem is the crapy connector, why only fails at 1024x768?

can be reproduced in all other 35ns pixelclock screenmodes
try the ugly 1280x512 pal-superhires-interlace for a while
or sometimes it happens with super72 at 800x600, too.

its a bug on the a1k2-mainboard, havent heard from any equal problems from a a4k owner

[Cammy]

There's your problem then...

Try that patch.

Post #27 from novacoder resumes all.

yes


jens told me, that it could be possible the next batch of indivisions might come with a workaround for that hw-bug.

But this link speak how to solve it... or its just a joke?

Yes I burnt my fingers when I fixed mine......but it was worth it!

Looking at your signature seems like destroys the amiga too, heh

Seriously, this fix allow this resolitions without flickerings and glitches?
