 We had a similar problem  as Klaus had with EXPRESS. 
 
 
 We use a SUN 3/110 as the host system to our
 transputer network. It has a B011 board with 
 one t800 and a c004 on it. We have a number of
 transputer boards in an Inmos item box. 
 
 As we set up the configuration for the root 
 transputer  only, every thing works fine. When
 we connect the external transputers to the root
 and configure accordingly, the external transputers
 are not reached even if we proggrammed the cross-bar
 switch properly. 
 
 
 The only solution with the latest release of the EXPRESS
 is to take the  c004 switch out and hardwire an 84-pin header
 instead, for a fixed configuration. Then things starts
 moving. However, it is not the most desired solution, since
 we can not have the flexibilty of a crossbar switch, any more.
