/*  The Timex TS2068 and TC2068 joysticks are attached to port A of the AY-3-8912 sound chip.
	Reading port A of the sound chip is handled in the AyForTc2068 class.

	The bits read from port A have the following meaning:

		bit 0:		0 = up
		bit 1:		0 = down
		bit 2:		0 = left
		bit 3:		0 = right
		bit 4:		0 = fire		i believe this was WOS and seems to be wrong
		bits 5-7:	111				SAMS says bit 7 is fire which seems to be true
