That's right, you don't want it... then 8237DMA controller is on the PC main
board and though the CPU is tri-stated, it controls read/writes from/to
IO/MEM.... if the concept is to have a PC card plug into the C64, then
someone has to be awake to make the transfer else a DMA controller will be
needed between the two.
