2010-09-10	Added stubs for putting the emulated screen into a TIOS-drawn window.	Duncan Smith

2010-09-07	IO port framework now works	Duncan Smith
	A68k is defaulting all my address moves to word size, rather than long. I don't know whether I've expunged all this nonsense yet, but I'm trying. This version executes an infinite loop which writes 'A' to port 00h. I've patched in a write-to-console function on port 00h, so this can be used as a sort of debug monitor.
2010-09-06	Fixes to actually run code	Duncan Smith
	This is the version to run the first (trivial) infinite loop correctly. I hacked up the loader slightly to replace one of the (nonexistent) pages with a static byte array. z80 code executed: $4000: JP $4000 4000 c3 40 00 4003 This version also draws the opcode executed on the screen, to aid in debugging the emulator: move.b d0,$4c00+32*(128/8) Also, it turns out that I was mixing up the emulated SP (a4) and emulated PC (a6). That has been fixed. Further, it seems that movea defaults to a word operation in a68k. This led to pointer corruption, which has been fixed.
