    notes
  • does not support DMA to its 32 bit RAM - DMAfix solves this
  • after a reboot, DMA into Zorro II memory larger than 512 bytes causes the machine to hang - DMAfix helps here too
  • 68000 fallback mode - the software can switch from 68030 to 68000 but cannot switch back, the machine has to be switched off
  • memory is not available in fallback mode
