	Systems supported by this driver:

	Oric 1,
	Oric Atmos,
	Oric Telestrat,
	Pravetz 8D

	Pravetz is a Bulgarian copy of the Oric Atmos and uses
	Apple 2 disc drives for storage.

	This driver originally by Paul Cook, rewritten by Kevin Thacker.

/*
	Explaination of memory regions:

	I have split the memory region &c000-&ffff in this way because:

	All roms (os, microdisc and jasmin) use the 6502 IRQ vectors at the end
	of memory &fff8-&ffff, but they are different sizes. The os is 16k, microdisc
	is 8k and jasmin is 2k.

	There is also 16k of ram at &c000-&ffff which is normally masked
	by the os rom, but when the microdisc or jasmin interfaces are used,
	this ram can be accessed. For the microdisc and jasmin, the ram not
	covered by the roms for these interfaces, can be accessed
	if it is enabled.

	MRA8_BANK1,MRA8_BANK2 and MRA8_BANK3 are used for a 16k rom.
	MRA8_BANK2 and MRA8_BANK3 are used for a 8k rom.
	MRA8_BANK3 is used for a 2k rom.

	0x0300-0x03ff is I/O access. It is not defined below because the
	memory is setup dynamically depending on hardware that has been selected (microdisc, jasmin, apple2) etc.
