This forum is the best - I have no question about it. In few minutes kind people offer to help!
Do you think which chip could still be used?

We try very hard to make it a friendly place, I'm glad you're finding it so.

I'll need to solder a couple of legs onto it and test it but I suspect so yes.

Failing that I likely have a spare 65XE board that works.

That would be great big thanks! I will be buying rounds on 8th of October - no question about it!

@mgi I had to repair one leg and it boots now.

Looks great! If someone wanted ever to test in Sysinfo is the option to check for 'Bad GTIA'.

This is how it should look like:

This is how it looks on mine:

It gets worse :)
I was testing on this demo https://demozoo.org/productions/62247/? ... W8iffIYtxw

It should be like this:

And on my CRT looks like this:

I know this GTIA boots, not sure about anything other than that
