CPU card
A which is installed in CPU card slot A . In CPU card slot B , a
terminator card is installed in place of an optional second CPU card

Symmetrical Multi-Processing
Symmetrical Multi-Processing SMP enables all CPUs in the system
simultaneously to service interrupts, access system memory, and perform I/
O operations. If your operating system does not support SMP, the system
adjusts the processing mode to Asymmetrical, meaning only the first CPU
accepts I/O interrupts, while the successive CPUs accept only
interprocessor interrupts.
Voltage Regulator Module
Each CPU must have a dedicated voltage regulator module (VRM) which
adjusts the voltage supplied to the CPU.
Floppy Drive Controller
The floppy drive controller can support up to two devices of 1.44-MB or
2.88-MB format.
