CV64/3D is ZII/III autosensing + the scandoubler (no flickerfixer!) only works in an A4000 video slot. (it won't work even if you modify the A2000 video slot to take it)
The PIV is a nicer card, but don't waste it in an A2000! Stick it in an A4000. Please. Zorro II is just so slow when you're running the card at modern resolutions - screen flipping takes several seconds when the entire bitmap chugs through the 3.5MB/s bus.
I have a CV64 in my A4000 and a CV64/3D in my A2000, guess which one is nice to use and which one is agonisingly slow?-) Both machines are 060/50. :-)
