I think the 520 has Quadra-like intvid if I remember right.

The bottom line on PDS cards is that they act like a NuBus card in NuBus
slot $E. There aren't too many video cards for PDS slots but I think the
few that there are aught to work. Though, with a built-in monitor I'd think
having a video card on a LC520 would be a bit unweildy. :)
