Motorola MVME2400 用户手册

B-1

The following table lists the general specifications for the MVME240x 
VME processor module. The subsequent sections detail cooling 
requirements and EMC regulatory compliance.

A complete functional description of the MVME240x boards appears in 
Chapter 3. Specifications for the optional PMCs can be found in the 
documentation for those modules.
