Introduction 4.1
The CPU/3 is a BSMS/2 subsystem. It plays a central role in the overall operation of
the BSMS/2. First, it relates all messages from the computer or BSMS keyboard to
the corresponding board (i.e., it serves as the master of the VMEbus). Second, it ma-
nages all functions in which more than one board are involved (i. e., autoshim,…).
The CPU is always located in the left-most slot 1 of the BSMS front rack as shown
in Figure 13.
