WDC1772 FDC Emulation

7 November 2004

Changed the indirect line signal system to a direct call back system since there are not many output lines and certain operations are dependant on how the host behaves at any time of receiving the signal. This also eliminates the need to find out later what line has been changed by the FDC emulation code.

There are call-backs for DRQ set, DRQ clear, IRQ set and IRQ clear states.
