1.4.2  Control Electronics Unit (CEU) 
The Control Electronics Unit (CEU) provides systems voltages, 
stabilization circuits, servo systems, and video processing.  The system 
computer, which is housed in the CEU, is based on the industry PC/104 
standard.  Use of this format for the system computer ensures the ability 
to upgrade as computer technology progresses.  All system input-output 
(IO) communications are routed through the CEU.  The CEU is equipped 
with an hourly time meter that registers the cumulative operating time of 
the CEU.  The characteristics for the CEU are listed in Table 1-7.
