C.1.10.3 Microphone
A SunMicrophone II mono microphone is included with each system unit.
C.1.11 Standard System Facilities
In addition to the previously listed features, the system unit or server provides the
following:
TOD/NVRAM for clock and identification functions
Flash PROM for operating system initialization. The flash PROM is
re-programmable through UNIX and OBP utilities.
Single LED for status. If LED is lighted, the system unit has power and some
functional intelligence through OBP.
C.1.12 Frequency Operation
The system unit or server provides three frequencies of interest: processor frequency,
system frequency, and SBus frequency. Processor frequency, system frequency, and
SBus frequency are:
Processor frequency, 167 MHz or 200 MHz
System frequency, 83.5 MHz or 100 MHz
SBus frequency, 25 MHz
