- 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?
