We have discovered that the Ironics VMEbus 512K dynamic RAM card raises DTACK on the bus before it is really done with the data; this causes serious problems in high speed applications, especially if 32-bit transfers are involved. When the bus master is a M680x0, everything seems to work fine, but very fast DMA devices encounter problems. John Nagle Ford Aerospace and Communications Corporation
