Ricoh G104 - Board Structure

OVERVIEW
G104 6-4 SM
6.1.4 BOARD STRUCTURE
The EGB (Engine Board) controls all of the machine functions and the handshake
with the CTL (Controller). The IOB (In/Out Board) controls input/output, drivers and
input/output -connections. The IOB is a part of the EGB expansion board.
Only two of the optional interface boards (IEEE1284, IEEE1394, IEEE802.11b, and
Bluetooth) can be installed.
The controller connects to the EGB through the PCI Bus (Peripheral Component
Interconnect Bus).
