Number	TBRegisterNumber::$06
Readable	TBRegisterReadable::Yes
Writable	TBRegisterWritable::Yes
Short Description	[[ShortDesc::Enables Acceleration, Lightpen, DivMMC, Multiface, Mouse and AY audio.]]

Bit	Function
7	Enable turbo mode, 0 = disabled (0 after PoR or Hard-reset)
6	DAC chip mode (0 = I2S, 1 = JAP) (Only VTrucco board, 0 after PoR or Hard-reset)
5	Enable Lightpen (1 = enabled) (0 after PoR or Hard-reset)
4	DivMMC automatic paging (1 = enabled) (0 after PoR or Hard-reset)
3	Enable Multiface (1 = enabled) (0 after PoR or Hard-reset)
2	PS/2 mode (0 = keyboard, 1 = mouse), exchanges the keyboard/mouse pins on the PS/2 connector (0 after PoR or Hard-reset)
1-0	Audio chip mode (%00 = AY, %10 = YM, %10 = Disabled) (a typo in documentation, defining %10 twice, I guess YM is %01)
