The I/O bus is an integral part of the controller board; it in
cludes seven sockets that allow the user to connect the various
peripheral adapters and options to the bus. These adapters and
options all use a common style of housing, permitting flexibility
in configuring the hardware. The cabinet design is such that the
adapters/options are fully recessed into the rear of the cabinet
when installed. The adapters/options do not require any pre
paration and can be plugged directly into the bus by the user.
The peripheral adapters are used to connect industry standard
printers, modems, and terminals to the bus. The bus is also used
for the connection of the memory expansion modules and other
special purpose modules.
Different versions of a “switcher” type power supply are used
depending on the power requirements of the different models of
the NCR DECISION MATE V. The power supply also provides
logical voltages to the bus for use by the peripheral adapters and
options.
