Yes, that's right. This page has more info: https://nerdlypleasures.blogspot.com/2021/10/apple-ii-compos... The PAL color circuit was initially an expansion card for the Apple II+ in 1979. The same circuit was built-in to the later Apple IIe and IIc models. A novel part of the design is that the TCA650 is actually a PAL decoder chip that is meant to split a composite video signal into YPbPr components. The Apple II drives the TCA650 in reverse to generate the composite signal. |
