In the end we wrote our our version of the configurer that will load a set of identical processes on to any array of transputers, and a 3L C multiplexor program to connect this to the host. 3L are very helpful, and have a technical note on configuration. From there it's just a matter of looking at some files generated by the configurer to understand the commands that the 3l loader (gloader.b4) uses, and to generate your own.
