AY-3-8912

Circuit diagram

A generic interface for the AY-3-8910 - the same principle would be used to connect an AY-3-8912:

Inputs

The inputs to this interface are as follows:

	DATA BUS - 8-bit non-multiplexed data bus (in this case from a Z80)
	A0 - address line zero
	/60h SEL - I/O address range $60-$6F select (for Z80, combine this with /IORQ)
	/RESET - CPU reset
	CLK - CPU clock (divided in two by the 74LS191 to give 2MHz in this case)
