Find a copy of the Z8530 SCC data sheet plus chapter 5 of the Apple
IIGS Firmware Reference where it describes the Hardware Control calls
(in particular GetSCC and SetSCC calls) and chapter 7 of the Apple IIGS
Hardware Reference where the hardware addresses allocated to the SCC
are listed (but not much else).
