Yes.  1,5,2 userland.  1.5ZA kernel.

(Well to be honest this particular time I didn't see the prompt but I 
could feel it.  I forgot to shutdown X separate to shuting down the 
machine and that left me with a forth prompt that wasn't visible. 
Fortunatly the forth command ``shut-down'' still worked fine :-)
