  Because the VME board is otherwise full of unsupported hardware that I
have no hope of ever finding documentation for.

  The console port comes out to a connector on the board's endplate.

  I have several VME enclosures and backplanes.  My rtVAX-300-carrying
VME board even came in one, with a disk subsystem integrated into a
quad-height VME card (floppy and SCSI hard drive) next to it.  Thing is,
I don't see ever being able to figure out the CSR addresses or anything
else about that hardware.  Maybe I'll get lucky..
