Baffa-2 Clock
The clock is the heart of the computer. It is what determines the time for each instruction and synchronization between the computer's circuits. This card provides two clock channels to Baffa-2 Computer: The clock 1 generates main timefor the CPU and peripherals of the computer. The clock 2 generates a differente speed to control secondary peripherals.
