CacheDoubler was for performance given the limits of the 603e 
processor.  Umax included the module for the later C600 models (I 
have the 240) and that 1 MB cache made the machine scream compared to 
the other Performa 6400 clones.  Indeed, I could approach native G3 
processor benchmarks.  That said, everything behind the 
processor/cache significantly bottled things up.  The bus was not 
well engineered and the PCI slots were not fully compliant with the 
PCI specs.  It was, for lack of a better word, a cheaply built box. 
It is, however, a great box to fool around with and tinker and learn. 
But it is a limited box which you will quickly find out.
