The 9V and 1.5V batteries are optional. They may be helpful to switch the TV to RGB mode automatically, without needing to activate it via buttons on the remote control. Instead of the batteries, you may also extract the voltages from elsewhere (like the CPC supply), valid are Pin8 = 9.5V - 12V (9V is actually a bit too low), and Pin16 = 1V - 3V.
