Help needed on CIA port usage

I'm trying to hook up Darlington drivers to the ports of CIA # 1, in process of
making a software-controlled relay sequencer out of a C64 computer. I obviously
have the keyboard circuitry removed.

Please download the quick 20KB picture:

From this circuit, I set the DDR to read PA0 as input and the rest (PA1 - PA7,
PB0 - PB7) as outputs, the simply poke the port with bits to enable the drivers
?

Please advice. Thanks.
Marcel
