Brad,
      
     I have run into trouble with my newly finished FRANCES memory 
expansion board.  The system boots fine with the LUCAS/FRANCES 
combination installed, but there is an addressing problem when accessing 
the FRANCES memory.  After doing a modeload, I use the Aztec DB debugger 
to check out the memory.  The data I enter is fine, but storing a byte at 
say $400000 causes the same byte to appear at $400000, $400040, $400080, 
and $4000c0.  By my figures this should mean something is wrong on A6 and 
A7 or with MQ1.  I can find no shorts or the like.  Using a logic probe 
shows activity on all of these lines.  I'm baffled.  Anything you can add 
would help.  Thanks.  Robert Taylor
