Front Adapter PCB
The Front Adapter PCB connects the CPU 68000 to the front panel. The front panels provides the control
and display elements.
The Front Adapter PCB reduces the 16-bit data bus to 8 bits, generates control signals for the front panel,
and controls the LC display (VIDEO RAM and LCD controller) or the EL display.
The power supply and the analog signals are led from the Motherboard PCB to the front panel through the
Front Adapter PCB.
