The CAM is the memory in the MEMC chip which is used to look up logical->
physical memory mappings.  Either RISC OS 3.1 is very buggy or you have
a faulty MEMC.  The CAM being corrupt means that the machine is unusable
when that part of memory has been accessed since the memory access will
be mapped to the wrong place.

Is the error happening only when you have a lot of tasks running?
