Indivision AGA 1200 small glitches
« on: October 29, 2009, 07:54:50 PM »
Hello

I have a indivision AGA 1200, i am very happy with it. But i have a little problem. When i turn on the machine, i get small graphical glitches in highgfx mode. They disappear after 5min when the machine gets warm. This only happen in 1024x768 highgfx mode. Im positive that the indivison is fitted firmly enough.

I have a amiga inc. a1200 2b motherboard. The indivision is a late batch, sanded and has 1.5firmware.

Some pictures:

One for Jens, perhaps?

I would have thought that any glitching would be more likely to happen when the machine warms up, rather than before it does.

Perhaps one of the pins isn't making the best contact and only improves once thermal expansion has kicked in?

Use a lower screen mode, see if it happens then.

Hence I asked him to change to a lower screen mode. If it is heat then it will glitch on higher resolutions.

@follet

Thats right but this resolution seems like a PAL one.

@mr byte

Are you using some application like blazewcp or fblit? Try to boot without startup-sequence.

Ok, i tried every screenmode i could find, and everyone works ok, but not highgfx mode. When i turn on my miggy it works fine for 10sec and then i get the glitches and after 5-10min its gone...very strange.

I dont have fblit installed, but i installed blazewcp today. But the glitches have lasted since i got the indivision 4 weeks ago.

I will try to boot without startup-sequence. I just need to wait for the machine to cool down :)

When i try to boot without startup-sequence everything is okay, but thats because highgfx mode is not loaded.

This isnt really a big problem for me. I can use my miggy many hour in row without no problem. Its just the first minuts when i turn my miggy on. But i like to have everyting in order.

Can it be the powersupply? I use a old a500 one, maybe it need some time to work properly?

I dont care about power supply :-(

My indivision runs good but im not try the highgfx mode (my a1200 is totally disassembly at the moment).

Yes im using the 1.5 firmware. But im lying to you guys, its not only in highgfx mode, but also in multiscan mode. So its seems glitches come when i use demanding screensmodes when the machine is cold :roflmao:

It does sound like something that might be caused by slight movement during thermal expansion.

I have already tried twice. I really dont like to take it in and out too many times. Im afraid the indivision will be broken. I pressed it really hard Both times (i heard the click noise). No change, same problem.

What do you propose? Try to take it off and install the indivision again?
