True and lets you stay away from PD0 and PD1 which set High/Low on A0 and A1 on 74HC154.
I just don't understand how my simple little program that is setting 4 pins High/Low does not work, but when I load a Peggy Sketch through TTL using FTDI cable it runs fine - complicated programs: LEDs running patterns, shades of grey, etc.
Was hoping there was something wrong with my code....
