Andrew,
I looked at peeron.com and the educational kit 9797-1 contains 3 NXT to 
RCX connectors(part # x1676).  Combining these with 2 NXT motors and the 
NXT brick will let you snap between motor number 3 and motor number 4 on 
the field.  If you do not have these search for a seller at brickmaster.com.
