u can add any ZorroII card, but ALL zorroII a1200 busboards DO NOT have DMA on them... so if the card in question needs DMA, then it won't work... rtg don't need dma, mainly ide/scsi cards need it... some might work but slower
also I heared that the DCE Cybervision 64/3D has a jumper to enalbe a special faster mode that is supported on the upper zorro slot of the zorroIV busboard... dunno if it works though...
