 SAM Coupe Driver - Written By Lee Hammerton


	Sam Coupe Memory Map - Based around the current spectrum.c (for obvious reasons!!)

	CPU:
		0000-7fff Banked rom/ram
		8000-ffff Banked rom/ram


Interrupts:

Changes:

 V0.2	- Added FDC support. - Based on 1771 document. Coupe had a 1772... (any difference?)
		  	floppy supports only read sector single mode at present will add write sector
			in next version.
		  Fixed up palette - had red & green wrong way round.


 KT 26-Aug-2000 - Changed to use wd179x code. This is the same as the 1772.
                - Coupe supports the basic disk image format, but can be changed in
                  the future to support others
