Data acknowledge output of the parallel MPU interface, active LOW,
otherwise high impedance.
If pin 68 (SEL_MPU) is HIGH, this is the read/write signal of the parallel MPU
interface. Otherwise it is the I
If pin 68 (SEL_MPU) is HIGH, this is the address signal of the parallel MPU
interface. Otherwise it is the I
If pin 68 (SEL_MPU) is HIGH, this is the chip select signal of the parallel

LOW slave address = 88H, when HIGH slave address = 8CH.
digital ground 7
Lower 4 bits of the data port; if pin 68 (SEL_MPU) is HIGH, the data bus of
the parallel MPU interface is used. If pin 68 is LOW, then the UV lines of the
video port are used.
