Looks like its workable Kip, but on that controller, the board should be 
extended on the sides in order to engage the grounding ears.  Soldering 
another small piece of double sided pcb material to the now grey areas 
beside the connector pattern, extending it out to engage the clips beside 
the coco's connector (or the MPI's as the case may be) using a strip of 
copper pcb tape to do the bridging.  Otherwise there is only one ground 
connection to the controller through the 40 pinner, and that is not enough 
to result in dead reliable data throughput, as anyone who has ever tried to 
use a Y connector knows well).  Then, just to enhance the connection, 
Creswell sells a silver plating kit that could do a hundred or more plating 
jobs.  Tarnished silver is still a decent connection.  Many times better 
than the lead oxide on those ears now.
