Figure 50 - CPU_TA Board Circuit
The function of the circuit is to extend the TA signal, to ensure the CPU correctly registers it. Resistor R2 must be
fitted to ensure correct operation of the TA input to the processor. It is recommended that the logic is fitted close to
the ZL50110/11/12/14 and that the clock to the 74LCX74 is derived from the same clock source as that input to the
ZL50110/11/12/14.
