by the way, Retina Z2 doesn't have picasso96 or cybergraphx drivers, so you have to stick with its RetinaRTG drivers which kind of sucks. That's why it's considerably less valuable than other boards. Picasso II is gold, cause it's one of the best graphic cards that work on Z2. A lot of people hunt that one. Retina Z3, while having picasso 96 drivers (unlike Z2) not very desirable because it lacks pass through port. And itdoesn't work on Z2. Cybervision 64 is the best budget Z3 graphics board. I consider Picasso IV in its own class entirely, which is great value considering the AGA scandoubler it has and Z2/Z3 compatibility.
