}Yes, it should only cost you $100.  But be aware that putting an 8-bit
}card into the same double-segment (B000->CFFF) as a 16-bit card will cause
}the 16-bit card to be accessed 8 bits at a time.  In other words, your
}16-bit VGA will act like an 8-bit VGA.

You've got it backwards.  Any 16-bit card in a double segment forces all
cards into 16-bit accesses.  This means that you will have to set your
VGA to 8-bit operation in order to be able to use the mono board (unless you
can find a 16-bit mono adapter--let me know if you do!).  If you leave
your VGA in 16-bit mode, you'll get some interesting effects as all the
attribute bytes written to the mono board get sent to bit heaven....
