It would be interesting to know which Apple part numbers go with those chips.  Caboose, for example, sounds like an earlier version of the CUDA chip (341S0788, IIRC).  I've seen a version of it labeled 341S0060 (again, IIRC) on a 68040 logic board which transplanted just fine into a PCI Power Mac which would normally have the 0788 part.  Makes me wonder if the 0060 is Caboose and 0788 CUDA.
