Put it in a container along with all those elderly 68020's from the Sun-3 
days. 8-)

THE CPU out of the IPX is a completely different one to the CPU in a 
4/280, so if they were the same, then yes, you probably could swap them. 
This is not taking into account the physical differences...

The only machine(s) it could be used in are others with the Sun-4c kernel 
architectures. I don't know if there would be any problems besides the 
CPU clock speed issue to resolve, but there probably would be since a 
machine like an SS2 (whichis a Sun4c box) uses a different cache design 
to other Sun4c boxes.

Craig.
