Technically possible: Yes.


  • Good luck finding new hardware which is modern enough to have a 64 bit CPU yet still has ISA slots. Or replacements for them when they die.
  • ISA is limited to 16 MB address space. Thus the driver for the device will need to use bounce buffers. That will limit performance.
  • Finding the X64 drivers for the device can be interesting.
