In some cases, you may see conventions such as 'X-MP4/28' or 'Y-MP8/4128'.
In these examples, the '4' in 'X-MP4/28' means the total number of cpu's that
the system can hold, and the '28' means that the system has '2' cpu's installed
along with '8' mega-words of on-board memory.
The same is true for the Y-MP.
