The models 311 and 313 are 5-slot baseplates, and the model 323 is a 10-slot
baseplate. Since they do not require a plug-in CPU module, all numbered
slots, including Slot 1, can be used for I/O or Option modules.
The memory back-up battery is located in the Power Supply module; so if
the Power Supply is unplugged from the baseplate, the battery will be
disconnected from the memory circuits, which are located on the backplane
circuit board. However, the backplane circuit board contains a high value
capacitor, called a ”super capacitor,” that can store enough charge to
maintain the memory circuits for a short period of time if the Power Supply
is removed or its battery is disconnected. See the section “Super Capacitor
Memory Backup” in Chapter 6.
