A couple of those have worked fine for me too, but every A1200 motherboard is different. Most of the time the older hardware is fine, but I've noticed small little faults on a couple of different A1200's (and so have others).
Actually some A1200's have sound problems and video tearing issues, but the problems don't show up on all motherboards even version numbers seem to be not a guide either to determine if fixes will be needed or not.
Some 1200's work fine with the ACA cards even though it's stated that timing fixes are needed.
It appears to be luck of the draw.
There are long technical posts about this issue on EAB and Amibay which explain it better than me.
040/060 cards have a tendency to show the timing faults more often than 030 cards, especially when clocking the 060 at 80MHz +
Just need to do a google and find a lot of people having timing issues.
The best advice is to get the card you want, try it and if the amiga shows faults then get the timing fixes.
TBH I find the ACA card's to be faster than the Bliz 030. Must be the faster more modern RAM that they come with. The ACA 1231 is a very good card.
