Video tells itself.

Artifacts (random black lines) happen when CF is reading.

Your comments will be highly appreciated

Could be a power/noise issue. Check if your Indivision has had the fix applied (you can see extra components soldered on top of the existing components inside the socket). If it was bought within the last few years, it should have this fix. Even with these fixes however, my Indivision still had this kind of noise when the floppy drive was accessed, but I fixed it 99% by routing the VGA cable differrently inside the machine so it looked like a noise issue.
Inside my A600, the 5V line was only around 4.75V-4.8V due to loss in the PSU cable/connector and I think this could have made the problem worse.

you are right, i think its a power issue. Because if i disable ACA1233, artifacts are bearly seen. I will also measure the voltage on 5V rail.
