It is supposedly intended to allow users to develop their own boards to interface to the CPU. Has anyone out there tried to do this? In particular, have they tried to build a DMA interface to the bus? I'd be interested to hear of anyone's experiences (e.g. difficulty of getting things to work, speeds achieved, etc.) Thanks in advance, Bruce Davie Bell Communications Research Morristown, NJ bsd@bellcore.com
