This card needs Super Buster 11 when operating with DMA cards but obviously it isn't your issue here.
Hardware wise, i would look closely to every solder joints because this card can bend a bit in the computer and there might be microcracks somewhere.
If you can, check the card in another computer, and in another zorro slot.
Software wise, you could also try the latest P96 as something new in your current setup might conflict with the old Picasso96 from Aminet.
I am gonna try in another 3/4000 when I can get access to one.
I have checked as closely as I can and I can't see anything obviously off. Though, the solder joints are so small it's really hard to see without a microscope or a very good magnifying glass, the one I have isn't very good at all.
The only new thing in my setup i that the 060 replaced my old 040 on my CS MkII. Though, these problems started before I did that so I don't think it's related. Tried a number of different 68060 libraries as well and no real change, except for that one bad image that was a one time event so more like a fluke, which only suggests that this is not the issue either. As I've said, the computer is rock solid a long as I don't try to activate the card.
Two days ago I asked hese on amibay if he thought it was something repairable and he replied that it depends on what the issue is. There are two faults that makes it impossible to repair so I can only hope. But I'm still gonna try the card in another computer before just to make sure. I can't rule out that there's something else wrong that only affects this card so before sending it away I need to do that check.
Even if I may end up buying a ZZ9000 I still would like to get this card working. Nice thing to have for some other setup in the future.
