A99 Motherboard
The A99 Motherboard assembly provides a common point of contact for voltage and
signal distribution. The Motherboard also buffers the external monitor signals and
routes the buffered signals to the EXT MONITOR connector. See ''A99
Motherboard'' in chapter 9 for a list of all signals that are distributed via the
Motherboard assembly.
A100 Disk Drive
The internal A100 Disk Drive assembly stores and retrieves information from 3.5-inch
flexible disks. This assembly is controlled by the A7 CPU assembly. See the
description of the Disk Controller in ''A7 CPU'' (earlier in this chapter) for additional
information.
A101 Display
The A101 Display assembly shows processed data sent by the A7 CPU assembly. See
the description of the Display Controller for the ''A7 CPU'' (earlier in this chapter) for
further details.
A102 DC-DC Converter
The A102 DC-DC Converter assembly generates the driver supply voltages for the
A101 Display assembly and routes the display data from the A7 CPU assembly to the
Display assembly.
