Mechanical Description
The 130XE computer console contains a single motherboard which houses all the chips of the
system and provides connectors for interfacing external modules to the console. It includes
the CPU, ANTIC, GTIA, POKEY, PIA, FREDDIE, RAM, ROM Operating System, and
includes all functions. The motherboard uses a common address bus, data bus and clock lines.
The sixteen-line address bus allows the microprocessor to directly address 64K of memory
locations. The eight-line data bus provides the communication and data path between the
functional modules. The various power requirements are routed from the power supply
throughout the console.
The keyboard is connected to the PC Board by a 24-conductor foil cable.
Figure 1-4 is a block diagram of the functional flow of the 130XE.
