The frame buffer boards for mono and color are different; one is 8
bits/pixel, and the
other is one bit/pixel; the addressing is different.  It is more than
just additional
VRAM.

You are welcome to connect a mono monitor to a "color" pmax, and get a
grey-scale machine.
If you order off the menu, rather than one of the stock configurations, you
can configure a machine this way.  It may take a bit longer to be
shipped, as the
standard configurations are set up for immediate shipment (which is why
they are "stock" configurations); manufacturing doesn't have to think about
the order to ship it...
