Subject: Re: Using MicroSphere Color Graphics Board w/ Advent host adapter

Bridger:
I didn't think that software would be a problem, since as far as I can tell,
one uses Z80 port i/o to talk to the uSphere Color Board.  Of course, this
could still be a problem if it and Advent's Ram disk happen to use the same
port addresses.  I'd probably better look into that, too.  

What I was originally concerned about was that Color Board uses the rear-most
SIO chip (socket on a ribbon cable plugs in underneath the SIO), and that
since the Advent Host Adapter comes up right next to this chip, it would be
physically impossible to install it.
